Food & Allergy Testing in North Mississippi: The Complete Guide to Identifying Hidden Food Triggers Behind Bloating, Fatigue, and Inflammation

You have tried everything. You cut out gluten for a month. You went dairy-free. You tried that elimination diet your friend swore by. You bought the probiotics, the digestive enzymes, the apple cider vinegar gummies. Some weeks you feel a little better. Most weeks you still feel off — bloated by 3 p.m., foggy through your afternoon meetings, achy in your knuckles, breaking out on your jawline, exhausted after dinner even though you went to bed at a reasonable hour. Your labs come back “normal.” Your primary care doctor says you look healthy. And yet you know something is not right.

If that paragraph reads like a description of your own life, you are not alone, and you are not imagining it. Food can be a quiet, slow, persistent driver of inflammation in the body — and the symptoms it produces rarely look like the textbook image of a food allergy. They look like fatigue. They look like joint pain. They look like “just getting older.” They look like a stubborn five pounds you cannot shake. They look like skin that flares for no apparent reason. And the kicker is this: the standard food allergy test most people get does not catch any of it.

This guide is for the patient who suspects food is part of the problem but cannot pin down which food. It is the most thorough explanation we can give you of how modern food and allergy testing works, what the four immune pathways actually measure, what symptoms our 352-marker panel is designed to investigate, what a visit to one of our North Mississippi clinics looks like, and how to use your results to build an elimination and reintroduction plan that actually changes how you feel. We see patients from Oxford, Corinth, Olive Branch, and the surrounding communities every week who arrive frustrated and leave with a clear path forward. Our goal with this article is to give you that same clarity before you ever walk in the door.

If you would rather skip ahead and book a consult, you can book online here or call 877-665-6767. Otherwise, settle in. There is a lot to cover, and most of it is not information you will get at a typical office visit.

Why Traditional Allergy Testing Misses the Foods That Actually Make You Feel Bad

When most people hear the words “food allergy test,” they picture one of two things. They picture the skin-prick test in an allergist’s office, where a grid of small scratches is made on the forearm and tiny drops of food extract are placed on each one. Or they picture a basic blood test that returns a short list of foods marked positive or negative. Both of these tests have real value. Neither of them is designed to find the kinds of food reactions that make you feel chronically inflamed, bloated, foggy, or fatigued.

Here is why. The standard food allergy test — the kind your allergist runs, the kind your primary care office orders — measures only one immune pathway. It measures IgE, an antibody class that triggers immediate, classical allergic reactions. IgE is the antibody that causes hives within minutes of eating shrimp. It is the antibody that swells a child’s throat after a peanut. It is the antibody behind anaphylaxis. IgE reactions are dramatic, fast, and visible. They are also relatively rare in the adult population, and they account for only a small fraction of the food-related symptoms most patients experience.

Most chronic, food-driven symptoms — the slow-burn ones — are not IgE reactions at all. They are reactions in other immune pathways that the standard test does not measure. So a patient who is genuinely reactive to eggs in a delayed, inflammatory way will have a normal IgE test, be told they are not allergic to eggs, and go on eating eggs every morning while their body keeps producing low-grade inflammation week after week. They never connect the dots, because the test that was supposed to find the problem only looked in one of four places.

This is not a failure of allergists. It is a limitation of the tools traditional allergy testing was designed to use. Skin-prick and IgE blood panels exist to identify life-threatening allergies, and they are excellent at that job. They were never built to identify chronic, low-grade food reactivity. For that job you need a panel that measures more pathways. That is exactly what our 352-marker panel does.

The Difference Between a Food Allergy and a Food Sensitivity

One of the most common questions we hear is some version of “Wait, am I allergic to dairy or sensitive to dairy? Is there a difference?” There is a real difference, and it matters.

Food allergy: a fast, IgE-mediated reaction that typically shows up within minutes to two hours of eating a food. Symptoms can include hives, swelling of the lips or throat, wheezing, vomiting, and in severe cases anaphylaxis. These reactions are immune-system emergencies and require emergency planning, including epinephrine availability when appropriate.
Food sensitivity: a slower, often delayed reaction that can show up hours or even days after eating a food. Symptoms tend to be inflammatory and systemic — bloating, fatigue, brain fog, joint aches, headaches, mood shifts, skin flare-ups, sinus pressure, post-meal sleepiness. These reactions are not life-threatening, but they erode quality of life over months and years.

The standard IgE-only allergy test catches the first category and misses the second. Our 352-marker panel catches both.

The Four Immune Pathways Explained

To understand why our panel is built the way it is, you have to understand the four pathways it measures. Each pathway is a different way the immune system reacts to a food, and each pathway tells you a different piece of the story. Most labs only run one. We run all four for every food on the panel.

Pathway 1: IgE — The Classical, Immediate Allergic Response

IgE, short for immunoglobulin E, is the antibody class your immune system makes when it decides a food is a genuine threat that demands an immediate response. When you eat a food you are IgE-reactive to, IgE antibodies bound to mast cells in your tissues recognize the food protein, and the mast cells release a flood of histamine and other inflammatory chemicals within minutes. The result is the classic allergic picture: hives, itching, swelling around the lips and tongue, throat tightness, wheezing, vomiting, and in severe cases the cardiovascular collapse of anaphylaxis.

IgE reactions are fast, visible, and dangerous. They are also relatively easy to identify because the timing is so tight. Most patients with a true IgE allergy already know about it — they know shellfish puts them in the emergency room, they know peanuts swell their throat, they know strawberries give them hives within twenty minutes. What they may not know is the full scope of their IgE reactivity. Many people are mildly IgE-reactive to foods they have not realized are bothering them, and those mild reactions still drive low-grade inflammation, sinus congestion, and skin issues.

Our panel measures IgE for all 88 foods. If you have a clinically significant IgE reaction to a food, this part of the panel will flag it. But IgE alone is not the whole story, which is why most patients who feel chronically off do not have abnormal IgE results — their issue lives in the other three pathways. That is why our panel does not stop here.

One important note about IgE: if you already have a documented severe IgE allergy — a peanut allergy with prior anaphylaxis, for example — this panel is not the test you need. You need an emergency action plan, an epinephrine auto-injector, and a relationship with an allergist who can manage that diagnosis. Our food and allergy panel is a tool for chronic, unexplained symptoms, not for managing severe, known allergies.

Pathway 2: IgG — The Delayed, Slow-Burn Sensitivity Reaction

IgG, immunoglobulin G, is the antibody class behind most of what patients describe as “food sensitivity.” Unlike IgE, IgG reactions are not immediate. They unfold over hours and sometimes days. You eat the food on Monday morning. By Monday night you feel bloated. By Tuesday afternoon your knees ache and your sinuses feel full. By Wednesday you are foggy and exhausted, and you have no idea any of it is connected to Monday’s breakfast. This delayed timing is the single biggest reason food sensitivities are so hard to identify on your own. The cause-and-effect window is too wide for the human brain to track.

IgG sensitivity is also dose-dependent and cumulative in a way IgE is not. A single bite of a moderately reactive food may not cause noticeable symptoms. But that same food eaten daily, in regular portions, can create a steady drip of low-grade inflammation that becomes your new baseline. Patients often describe finally feeling “normal” after eliminating an IgG-reactive food and realize, in retrospect, that they had not felt normal in years. They had simply gotten used to feeling tired and bloated.

This is the pathway where most chronic-symptom triggers actually live. Bloating that flares two to twenty-four hours after meals. Brain fog you cannot explain. Joint stiffness that comes and goes without an injury. Skin that breaks out on the jawline or chest. Sinus pressure that never quite resolves. Fatigue that no amount of sleep fixes. Stubborn weight that resists every diet. Post-meal sleepiness so heavy it feels narcotic. These are IgG-driven patterns more often than not, and they are exactly what our panel is built to find.

IgG is not, by itself, proof that a food is hurting you. Some IgG response to commonly eaten foods is normal — your immune system meets foods every day and produces antibodies as part of normal recognition. What matters is the level of IgG response and how that response correlates with your symptoms and the other three pathways. Reading IgG in isolation is a common mistake. Reading IgG alongside IgG4 and C3d is what gives the panel its real diagnostic power.

Pathway 3: IgG4 — The Tolerance vs. Reactivity Differentiator

IgG4 is a subclass of IgG, and it does something subtle but extremely important. IgG4 antibodies are produced when the immune system has been exposed to a food repeatedly over time and has begun to develop a kind of tolerance to it. In simple terms, a high IgG4 response to a food often means your immune system has learned to coexist with that food rather than fight it. A high IgG response with a high IgG4 response can suggest acquired tolerance — the food shows up as “reactive” on a basic IgG-only panel, but in real life your body has adapted and the food is not actively driving inflammation.

Without IgG4, you cannot tell the difference between a food your body is genuinely fighting and a food your body has learned to tolerate. This is one of the biggest weaknesses of cheap, mail-order IgG-only kits. They flag dozens of foods as “reactive,” patients eliminate everything on the list, and many of those foods were never actually a problem in the first place. The patient ends up with an unnecessarily restrictive diet, social anxiety around eating, and minimal symptom improvement. Adding IgG4 to the panel solves that problem.

In our panel, IgG4 is read alongside IgG to help differentiate between true ongoing sensitivity and acquired tolerance. A food with elevated IgG and low IgG4 is more likely to be a real driver of symptoms. A food with elevated IgG and elevated IgG4 may be one your body has adapted to, and may not need to be eliminated as aggressively. This nuance is the difference between a food plan you can actually live with and one that quietly takes over your life.

IgG4 also helps explain why some patients can reintroduce a food successfully after a period of elimination while others cannot. The development of IgG4 tolerance is part of why the structured reintroduction protocol works — it lets the immune system reset its relationship with a food and, in some cases, build the very tolerance that IgG4 represents.

Pathway 4: C3d — The Active-Inflammation Signal

The fourth pathway is the one most patients have never heard of, and it is the one that often makes the biggest difference in interpreting results. C3d is a fragment of the complement protein C3, and it is produced when the complement system — a cascade of immune proteins that amplifies inflammatory responses — gets activated. When C3d shows up bound to a food protein, it is direct evidence that the immune system is mounting an active inflammatory attack on that food right now.

C3d takes IgG out of the realm of “antibody is present” and into the realm of “immune system is currently inflamed by this food.” A food with high IgG and high C3d is a food that is actively driving inflammation in your tissues today. A food with high IgG but low C3d is a food your body has produced antibodies to but is not currently mounting a strong inflammatory response against. The first food belongs at the top of your elimination list. The second food may be lower priority.

For patients whose primary symptoms are inflammatory — joint pain, skin flares, sinus issues, headaches, swelling, post-meal redness or warmth — C3d is often the most actionable pathway on the panel. It identifies the foods that are not just on the immune system’s radar but are pulling the trigger on inflammation in real time. Those are the foods most likely to produce a noticeable difference in how you feel within the first two to four weeks of elimination.

This is why our panel is a 4-pathway panel rather than a 1- or 2-pathway panel. IgE finds emergencies. IgG finds delayed sensitivities. IgG4 separates true sensitivity from acquired tolerance. C3d identifies which of those sensitivities are actively inflaming your body right now. Each pathway answers a different question, and you need all four answers to make a confident plan.

What the 352-Marker Panel Actually Measures

The math is straightforward. Eighty-eight common foods, each tested across the four immune pathways above, equals 352 individual immune markers per patient. That is the total surface area of information our specialty partner lab returns from a single in-clinic blood draw.

The 88 foods on the panel are not a random list. They are the foods that, in clinical practice, account for the overwhelming majority of food-related immune responses in the American diet. They cover every major food group, including the ones you eat almost every day without thinking about it. We will not list every single one — that level of detail comes with your results — but here is the shape of what the panel covers.

Food Categories Covered by the Panel

Dairy: cow milk, casein, whey, common cheeses, yogurt cultures, and related dairy proteins. Dairy is one of the most frequently flagged categories because of how often it appears in the modern diet.
Gluten and wheat: wheat itself plus the specific protein components of wheat, including gluten. This matters for patients who have already removed wheat and want to know whether the issue is wheat broadly or gluten specifically.
Eggs: both egg white and egg yolk, since they contain different proteins and people often react to one and not the other.
Meats: common animal proteins including beef, pork, chicken, and turkey.
Seafood: a range of fish and shellfish that account for most of the seafood-related reactions seen clinically.
Nuts and seeds: tree nuts and common seeds that show up in baking, snacks, and cooking oils.
Legumes: peanuts, soy, beans, and lentils — a category that is often missed in standard panels and frequently overlaps with patients who have unexplained gut symptoms.
Vegetables: nightshades, cruciferous vegetables, alliums, and other commonly consumed produce.
Fruits: citrus, berries, tropical fruits, and orchard fruits.
Grains beyond wheat: corn, rice, oats, and other grains that frequently replace wheat in modified diets.
Spices and additives: common culinary spices and a handful of food additives that show up across the modern processed-food supply.

The point of casting a wide net is not to find a long list of foods to take away from you. The point is to give you a complete map. Patients are routinely surprised by what shows up and what does not. The food they were sure was the problem turns out to be fine. The food they had no suspicion about turns out to be lit up across multiple pathways. Without measuring all four pathways across all 88 foods, you would never see the pattern.

Symptoms This Panel Is Designed to Investigate

The panel is not for everyone. It is specifically designed for the patient who is dealing with chronic, unexplained symptoms that they suspect — but cannot prove — are related to food. If you read the list below and recognize yourself in three or more items, this is exactly the patient population the panel was built for.

Bloating and abdominal distention: the kind that turns up after meals and stays for hours, that makes your waistband feel different in the evening than it did in the morning, that is not explained by anything obvious.
Gas and abdominal discomfort: recurring gas, cramping, or low-grade discomfort that flares with certain meals and quiets down on others without a clear pattern.
Eczema and chronic skin flare-ups: patches of dry, itchy, inflamed skin that come and go and are not fully controlled by topical creams. Eczema in adults is one of the most consistent patterns we see tied to delayed food sensitivities.
Hives and itching: particularly recurring or chronic hives that are not tied to a clear allergen and that often persist for weeks or months at a time.
Brain fog: the experience of feeling like your thoughts are moving through molasses, of struggling to find words, of needing to re-read sentences, of feeling mentally tired even when you are not physically tired.
Fatigue and post-meal sleepiness: persistent low energy, especially the kind that gets dramatically worse after meals — the post-lunch crash that feels narcotic and is not explained by what you actually ate.
Headaches and migraines: recurrent headaches that do not follow a clear trigger, particularly tension headaches and migraines that flare a few hours to a day after meals.
Joint pain and stiffness: inflammatory-feeling joint pain in fingers, knees, hips, or shoulders that is not explained by an injury or formal arthritis diagnosis.
Mood swings tied to meals: noticeable irritability, anxiety, or low mood that flares in the hours after eating and is not consistent with your underlying baseline.
Stubborn weight that will not move: the kind of weight plateau that holds even when calories are controlled, when sleep is reasonable, and when you have ruled out the obvious thyroid and hormone issues. Inflammation drives water retention and metabolic resistance, and food sensitivities are a quiet but real driver of both.
Skin breakouts on the face, chest, or back: particularly cystic, inflammatory acne in adults that does not respond to standard topical or oral treatment.
Sinus congestion and post-nasal drip: chronic sinus pressure, congestion, or drainage that has been written off as “allergies” but does not respond well to seasonal antihistamines.
IBS-like symptoms: alternating constipation and diarrhea, urgency, or unpredictable bowel habits that have been labeled “irritable bowel syndrome” without an underlying cause being identified.
Reflux and heartburn: chronic reflux that flares with meals and does not fully resolve with standard acid-blocking treatment.
Restless sleep and middle-of-the-night waking: particularly when paired with bloating or reflux at bedtime, which can be a downstream effect of food-driven inflammation.

This is not an exhaustive list, and the panel can investigate symptoms beyond the ones above. But these are the categories where we see the most consistent improvement when patients identify and remove the right foods. If your concerns extend into hormonal territory — energy, libido, body composition, weight that resists everything — it is also worth understanding how food sensitivity overlaps with our work in TRT, HRT, and medical weight loss. Inflammation does not exist in isolation. It interacts with every system in the body.

How a Visit Actually Works

One of the most reassuring things we can tell patients is that this is not a complicated process. There is no DIY mail kit. There is no finger-prick at-home test. There is no home-shipped saliva swab. You come into one of our clinics, our clinical team draws your blood, the sample goes to our specialty partner lab, and your results come back to your provider for review with you. Here is the full flow.

Step 1: Schedule a Consult

You start by booking a consult, either online at /book or by phone at 877-665-6767. The consult is a chance for your provider to take a careful history — what symptoms you have, how long you have had them, what you have already tried, what your diet currently looks like, what other conditions you are managing, and what your goals are. The consult is also when we confirm that this panel is the right test for what you are dealing with. For some patients, food and allergy testing is the right first step. For others, we may recommend running it alongside other lab work to get a fuller picture. Our how it works page walks through what to expect at the consult itself.

Step 2: Arrive at the Clinic for Your Draw

You can complete your draw at any of our North Mississippi locations — our Oxford clinic, our Corinth clinic, or our Olive Branch clinic. The full list of addresses, hours, and directions is on our locations page. The blood draw itself is done by our clinical team, in a clinical setting, with the same standards as any other in-office lab. You do not have to fast for this panel. You do not need to stop your usual medications unless your provider specifically tells you to. The draw takes about 15 minutes start to finish, including check-in.

Step 3: The Sample Goes to Our Specialty Partner Lab

After your draw, your sample is shipped to our specialty partner lab — a CLIA-certified laboratory that specializes in immune-mediated food reactions and runs the four-pathway panel as a standardized assay. We use a partner lab specifically because this is a specialized test that requires equipment and validated protocols you would not find in a standard hospital lab. The sample is processed against the full panel of 88 foods across the four immune pathways, and the lab returns a structured, color-coded report.

Step 4: Wait Two to Three Weeks for Results

Results typically return in 2 to 3 weeks. We know that is longer than a standard CBC, but the assays involved are more complex than the lab work most patients are used to. We will reach out as soon as your results are in.

Step 5: Provider Results Review

Once your report comes back, your provider sits down with you to review it in detail. This is not a quick “here is your number” phone call. It is a real, structured conversation about what the report says, which foods showed up in which pathways, what that pattern means for your symptoms, and what your elimination and reintroduction plan looks like in practical, day-to-day terms. Patients who live a drive away from any of our clinics frequently do this review by telehealth, which is one of the reasons our service area extends well beyond Oxford, Corinth, and Olive Branch.

Step 6: Follow Through on the Plan

The test by itself does not change how you feel. The plan does. The protocol you build with your provider — what to eliminate, in what order, for how long, and how to reintroduce — is what produces the actual symptom changes. We will walk through that protocol in detail later in this guide.

How to Read Your Color-Coded Report

The lab returns your results in a structured, color-coded format that lists every one of the 88 foods alongside its result in each of the four pathways. The color coding is straightforward and consistent across pathways.

Low or non-reactive (typically green or unmarked): the food shows little to no immune response in this pathway. There is no clinical reason to eliminate this food on the basis of this result alone.
Moderate reactivity (typically yellow): the food shows a measurable immune response that is meaningful but not dominant. These foods are usually candidates for reduced frequency rather than full elimination, depending on how the pathways line up.
High reactivity (typically red): the food shows a strong immune response in this pathway. High-reactivity foods, especially when they are high in more than one pathway, are the most likely candidates for full elimination during the protocol’s first phase.

The real diagnostic power comes from how the pathways stack on a given food. A handful of patterns are worth knowing.

High IgG, High C3d, Low IgG4

This is the most actionable pattern on the panel. The food is producing a delayed antibody response (IgG), the complement cascade is actively inflaming around it (C3d), and your immune system has not built tolerance to it (low IgG4). These are the foods most likely to produce a noticeable improvement when removed. They go to the top of the elimination list.

High IgG, High IgG4

This is a tolerance pattern. The food shows up as “reactive” on a basic IgG-only test, but the IgG4 result suggests your body has built tolerance to it. C3d behavior on the same food helps refine the picture — if C3d is also low, the food is unlikely to be a major active driver. These foods are not always the highest priority for elimination, and we factor that into your plan.

High IgE

This is the immediate-allergy pattern. If a food shows up high in IgE and you have any history of acute reactions to it, you and your provider will discuss appropriate emergency planning, including referral to an allergist where indicated. IgE flags are taken seriously regardless of how the other pathways look.

High C3d, Lower IgG

This is an active-inflammation signal even without the strongest delayed antibody response. It often points to foods that flare inflammation in the short term and are worth at least temporarily eliminating to see how you feel.

You will also see foods that are low across all four pathways. Those foods are good news — they are not driving any meaningful immune response, and they belong squarely in your “safe” column.

The Elimination and Reintroduction Protocol

The whole point of the test is to give you and your provider a target list. Once you have that list, the work happens at the dinner table. The protocol we use is built in three phases — elimination, observation, and structured reintroduction — and it usually unfolds over 8 to 16 weeks total, depending on your starting symptoms and how many foods came back high.

Phase 1: Elimination (Weeks 1 through 4 to 6)

The first phase is full elimination of your highest-reactivity foods. Typically that means the foods that lit up high in IgG, IgG4 (low), and C3d together, plus any IgE-flagged foods you are not already avoiding. Your provider will give you a personalized elimination list based on your specific report. We are deliberate about not making this list longer than it needs to be. A 12-food elimination is far more likely to be followed than a 30-food elimination, and the foods chosen are the ones most likely to actually move your symptoms.

What to expect in this phase:

Days 1 through 5: some patients feel slightly worse before they feel better. This is sometimes called a “withdrawal” phase, and it is most common with foods you were eating very frequently. Cravings, irritability, and mild fatigue are common and pass quickly.
Days 5 through 14: the first improvements typically show up here. Bloating drops, energy starts to lift, sleep deepens, skin starts to settle, and post-meal sleepiness eases. Not everyone notices changes in this window, but most do.
Weeks 2 through 4: deeper changes show up here — joint stiffness eases, brain fog lifts, sinuses clear, mood stabilizes, weight that had been stuck often starts to move.
Weeks 4 through 6: a more stable baseline. This is the new “floor” you are working from, and it is the floor we use as the reference point for reintroduction.

During Phase 1, we ask patients to keep a simple symptom journal. Nothing elaborate. A daily score on bloating, energy, mental clarity, joint comfort, skin, and sleep. The journal is what gives the reintroduction phase its diagnostic power, because without it you will not be able to tell whether a reintroduced food is actually causing a flare.

Phase 2: Stabilization (Weeks 4 to 6 through Week 8)

Once your symptoms have settled into a clear new baseline, you stay there for an additional two to four weeks. The point of this phase is to make sure the improvement is real and stable, not just a fluke. It also gives the immune system a chance to settle down — antibody levels do not change overnight, and even after the food is gone there is residual inflammation that takes time to resolve.

Many patients describe Phase 2 as the most powerful part of the protocol, even though nothing new is happening. They get used to feeling good. They start to recognize what their body actually feels like without low-grade inflammation. That clarity is what makes the next phase work.

Phase 3: Structured Reintroduction (Weeks 8 through 16)

This is where you start putting foods back, one at a time, in a structured way. Your provider will guide the order based on your report and your symptom priorities. The basic structure looks like this:

Day 1: reintroduce one food, in a moderate portion, in isolation. No new foods anywhere else in your diet that day.
Day 2: eat the same food again, in a similar portion, and watch your symptom journal carefully.
Day 3: rest day. No reintroduction. Continue tracking symptoms.
Day 4: if no symptoms have flared, the food is added back to your diet at moderate frequency. If symptoms did flare, the food is removed again and revisited later. Then you start the next food.

The reason we structure reintroduction this way — one food at a time, with a rest day, over 4-day blocks — is that delayed reactions can take 24 to 72 hours to show up. Reintroducing two foods at once is the single most common reason patients fail this phase. They reintroduce wheat and dairy in the same week, they flare, and they have no way to know which food was the culprit.

By the end of Phase 3, you have a personalized list of foods that are safe to eat freely, foods that are safe to eat in moderation, and foods that you and your body have agreed are not worth the cost of inflammation. That list is yours to use for the rest of your life, with periodic check-ins to see whether your tolerance has changed.

Who Is a Great Candidate, and Who Should Not Bother

We are direct with patients about who this panel is and is not for. There is no point spending $449 on a test that is not going to help you.

Great Candidates for the Panel

The patient who has tried elimination diets on their own and gotten partial results without ever pinning down the culprit.
The patient with chronic, unexplained symptoms — bloating, fatigue, brain fog, joint aches, skin issues, sinus pressure — who suspects food but cannot prove it.
The patient with stubborn weight or metabolic resistance whose other obvious workups have come back normal.
The patient with chronic eczema, hives, or adult acne that has not fully responded to topical and standard treatments.
The patient with IBS-style gut symptoms whose imaging and stool work have been unrevealing.
The patient who wants a more systematic, less guessing-game approach to figuring out what to eat.
The patient working on broader optimization — hormones, body composition, peptides, recovery — who wants food sensitivity off the list of confounders. This is why we frequently pair the panel with our work on TRT, HRT, semaglutide-based weight loss, peptide therapy, and NAD therapy.

Who Should Not Bother

The patient with a known severe IgE-mediated allergy that requires emergency planning. You do not need this panel — you need an allergist, an emergency action plan, and an epinephrine auto-injector. The panel is not a substitute for that care.
The patient who already knows exactly which foods bother them and is looking for confirmation. If you have a clear, repeatable, observable reaction pattern to a specific food and your goal is just to keep avoiding it, the test will likely tell you what you already know. Save the money.
The patient who is unwilling to do the elimination-and-reintroduction work after the test. The test alone does not change how you feel. The plan does.
The patient with active, untreated eating concerns. Restrictive food plans are not appropriate in that context, and we would much rather support you with appropriate care first.

If you are not sure which side of the line you fall on, that is exactly what the consult is for. We will tell you honestly whether this panel is the right test for you. Sometimes it is. Sometimes the right move is a different lab panel entirely — see our lab panels overview — and sometimes the right move is to start with a basic workup and revisit food testing later.

Cost, HSA/FSA, and Why We Do Not Run This Through Insurance

Our food and allergy panel is $449 all-inclusive. That price covers the in-clinic blood draw, the full 352-marker lab analysis at our specialty partner lab, and your provider results review. There are no add-on charges. There are no surprise bills. There is no “facility fee” on top. You pay $449, and that is the price.

HSA and FSA documentation is available on request, and the panel is generally an eligible expense under most HSA and FSA plans. We will provide an itemized receipt suitable for submission. Because the panel is medically ordered and tied to symptom evaluation, the documentation is straightforward.

We deliberately do not run this panel through insurance. There are a few reasons for that. The first is honesty about price. When you submit a specialty panel through insurance, the price you actually pay is determined by your deductible status, your plan’s contract with the lab, and a series of authorization and rejection steps that can produce a bill anywhere from $0 to several thousand dollars three months after the test was drawn. Patients hate that uncertainty, and we hate sending it. By offering the panel as a flat $449 service, you know exactly what you are paying before you walk in the door.

The second reason is access. Many insurance plans either do not cover the broader, multi-pathway food sensitivity testing or cover only a small fraction of it. Limiting the test to what insurance will pay for would force us back into IgE-only allergy testing — the very thing this guide is about going beyond. Our patients want the full picture, and the flat-rate model is how we deliver it without an insurance company gating which markers are run.

The third reason is privacy. Your immune-pathway food results are part of your private health record. Running the panel as a self-pay service means your insurance company is not building a profile from those results. For some patients that matters more than for others, but we want it to be your choice rather than something you stumble into.

North Mississippi Access

Our home is North Mississippi. We see patients every day from Oxford, Corinth, Olive Branch, and the surrounding communities. The full list of addresses and hours is on our locations page. Each of our clinics is staffed by a clinical team who can perform the in-office blood draw for this panel, and the consult and results review can be scheduled at the location most convenient to you.

For Patients in Oxford and the Lafayette County Area

Our Oxford clinic serves patients across Lafayette County and the broader Oxford metro area, including students, faculty, and staff at the University of Mississippi. The food and allergy panel is one of the most-requested services we run for our Oxford patient base, both for chronic-symptom investigation and as part of broader hormone and metabolic optimization workups.

For Patients in Corinth and Northeast Mississippi

Our Corinth clinic serves Alcorn County and the broader Northeast Mississippi region. Many of our Corinth patients commute in from Tippah, Tishomingo, and surrounding counties. The same panel, the same protocol, the same flat $449 price applies regardless of which clinic you use.

For Patients in Olive Branch and the DeSoto County Area

Our Olive Branch clinic serves DeSoto County and patients across the Memphis-area Mississippi suburbs. For patients who live just over the line in Memphis or Tennessee, the Olive Branch location is often the most accessible. The blood draw protocol is identical to our other clinics.

Telehealth for Consults and Results Review

The blood draw has to happen in person. Everything else does not. The consult and the results review can both be done by telehealth, which is how many of our patients who live a drive away handle the bookend appointments. You drive in once for the draw, and the rest of the protocol — the consult before, the results review after, the follow-up check-ins through reintroduction — can happen from your living room. This is part of why our service area effectively covers most of North Mississippi and the Memphis suburbs, not just the cities our clinics sit in.

Frequently Asked Questions

What is the difference between a food allergy and a food sensitivity?

A food allergy is a fast, IgE-mediated reaction that can include hives, swelling, throat tightness, and in severe cases anaphylaxis. It usually shows up within minutes to two hours of eating the food. A food sensitivity is a slower, often delayed inflammatory reaction driven primarily by other immune pathways — IgG, IgG4, and C3d — and can take hours or days to show up as bloating, fatigue, brain fog, joint pain, skin issues, and other systemic symptoms. Standard allergy testing only catches the first category. Our 352-marker panel catches both.

Can I keep eating something that comes back as “moderate”?

Often, yes — with a plan. Moderate-reactivity foods are usually managed by reducing frequency rather than full elimination, and the IgG4 and C3d behavior on the same food helps refine that. Your provider will give you a specific recommendation for each moderate food on your report. The goal is not to eliminate everything that shows any response. The goal is to remove the foods that are actively inflaming you and to reduce the foods that are on the edge.

How often should I retest?

For most patients, the right rhythm is to retest every 12 to 18 months, or sooner if symptoms shift significantly. Immune responses to foods can change over time, especially after a structured elimination and reintroduction protocol. A food that was high-reactive on your first panel may have moved to low-reactive after a year of strict avoidance. Retesting helps you decide whether previously eliminated foods can be safely reintroduced and whether new triggers have developed.

Does this replace skin-prick allergy testing?

No. The two tests answer different questions. Skin-prick testing is the gold standard for identifying immediate, IgE-mediated allergies — the kind that can cause anaphylaxis — and is best run by an allergist when severe allergy is on the table. Our panel includes IgE measurement across 88 foods and adds the three other pathways that drive chronic, delayed reactions. For patients with diagnosed severe allergies, skin-prick testing remains essential. For chronic, unexplained, food-related symptoms, our panel is designed for that exact use case.

Can pregnant women do this panel?

The blood draw itself is safe in pregnancy, but we generally recommend deferring elective food sensitivity testing during pregnancy. The reason is not the test — it is the elimination protocol that follows. Aggressive dietary restriction during pregnancy is rarely the right approach, and we would rather have you focused on consistent, high-quality nutrition for you and the baby. After pregnancy and once breastfeeding has stabilized, the panel is a great option. Talk with your provider about timing.

Does the panel cover gluten specifically?

Yes. The panel covers wheat as a whole food and gluten as a specific component, plus other grain proteins. This matters for patients who have already removed wheat and want to know whether their reactivity is to wheat broadly or to gluten specifically. It also matters for patients who suspect gluten but have had a normal celiac workup — IgG, IgG4, and C3d responses to gluten can flag delayed reactivity even when celiac disease itself has been ruled out. The panel does not diagnose celiac disease and is not a substitute for celiac testing where that is clinically indicated.

What if all my results come back red?

It happens, and it is usually less alarming than it looks. A panel that comes back broadly red typically tells us one of two things. Either there is a heavy load of dietary inflammation across many foods — common in patients with long-standing gut issues, chronic stress, or major recent illness — or there is a non-food driver of inflammation that is amplifying immune response generally. Your provider will help you interpret a broadly reactive panel and will not have you eliminate every red food at once. We pick the most reactive, highest-priority foods first, work on root drivers in parallel, and revisit the rest after the system has settled down.

Does insurance cover any of this?

We run the panel as a flat $449 self-pay service rather than billing through insurance. HSA and FSA dollars are typically eligible, and we provide itemized documentation for submission. We made this choice deliberately, for honesty about price, for access to the full multi-pathway panel, and for patient privacy. You will not get a surprise bill three months later.

Can I do this for my child?

Yes. Pediatric food sensitivity testing is a legitimate use of this panel, particularly for children with chronic eczema, recurrent stomach pain, behavioral changes tied to meals, or unexplained chronic congestion. Our clinical team performs pediatric draws, and we can talk through whether the panel is appropriate for your specific child during the consult. Pediatric protocols are gentler — we do not put children on aggressive multi-food eliminations, and the reintroduction phase is paced to the child’s situation. Mention that the patient is a child when you book so we can pair you with a provider who handles pediatric draws.

Do I need to fast before the draw?

No. Fasting is not required for this panel. The four immune pathways we measure are not affected by recent food intake in the way that glucose or triglycerides would be. You can eat normally on the day of your draw. If you are doing other lab work alongside the food panel — a comprehensive metabolic panel, a lipid panel, a hormone workup — your provider will tell you whether fasting is needed for the rest of the order. For the food and allergy panel alone, no fasting is required.

Does taking antihistamines affect my results?

Antihistamines do not meaningfully affect the antibody-based measurements on this panel. That is one of the practical advantages of an antibody-based blood test over a skin-prick test, where antihistamines can suppress the skin reaction and have to be stopped in advance. You can stay on your usual antihistamines through the draw. Steroids and certain immune-modulating medications are a different conversation, and your provider will review your medication list during the consult.

How soon will I feel different after the protocol starts?

Most patients notice the first changes — usually in bloating, energy, and sleep — within the first 5 to 14 days of elimination. More systemic improvements like joint comfort, brain fog, skin clarity, and sinus pressure tend to settle in over 2 to 6 weeks. By Week 6 to 8 of strict elimination of high-reactivity foods, most patients have a clear, stable new baseline, and they tell us the same thing: they did not realize how bad they had been feeling until they felt good. Your timeline depends on your starting load of inflammation, the specific foods involved, and how strictly you are able to follow the elimination phase.

Can I do this panel if I am already on a restricted diet?

Yes, and the panel can still be informative even if you have been avoiding common triggers like gluten or dairy for a while. Antibody levels do not vanish overnight, and the panel still picks up clinically meaningful reactivity for most patients on modified diets. That said, if you have been off a food for many years, the report on that specific food may understate your true reactivity. Mention any long-term avoidance during your consult so your provider can interpret the relevant markers in context.

Do I need to stop my supplements before the draw?

For most patients, no. Common supplements — multivitamins, fish oil, vitamin D, magnesium, probiotics — do not affect the antibody-based measurements on the panel. If you are taking a supplement that meaningfully suppresses immune function, your provider will discuss whether to pause it. As with medications, the safest move is to bring your full supplement list to the consult.

Closing: Stop Guessing, Start Measuring

If you have read this far, you are probably the exact patient this panel was built for. You have done the work. You have read the books, tried the diets, kept the food journals, switched the brands, googled at midnight. Some of it has helped. None of it has resolved the underlying problem. And the standard allergy test you got at your primary care office said you were fine.

You are not fine. You just need a tool that measures more than one immune pathway. Our 352-marker panel — 88 foods across IgE, IgG, IgG4, and C3d — is the most thorough, clinically actionable food and allergy test we offer, and it was designed for exactly the patient who has run out of guesses. The visit is a single 15-minute blood draw at our Oxford, Corinth, or Olive Branch clinic. The results come back in 2 to 3 weeks in a clear, color-coded report. The plan that comes out of those results is built specifically for your body, your symptoms, and your life.

The cost is $449, all in. HSA and FSA dollars are eligible. There are no surprise bills. The first step is a consult to make sure this is the right test for you. To schedule, call 877-665-6767, book online, or visit our food and allergy testing service page for more on the panel itself.

If you are not sure where to start, our contact page is the easiest way to reach us with questions, and our blog has more long-form guides on the related work we do — hormones, weight, peptides, body composition. Most patients eventually realize that food, hormones, sleep, and inflammation are all the same conversation. We are happy to start that conversation wherever it makes sense to start it. Ours is not a clinic that runs one panel and sends you on your way. We are here for the follow-through, the reintroduction, the next year of work, and the long arc of feeling better.

You do not have to keep guessing. You can measure. Start here.
