Food Sensitivity Testing in Spring, TX
Bloating after meals. Persistent brain fog. Chronic fatigue even though you’re eating clean. Skin flare-ups with no obvious trigger. You’ve tried elimination diets, gone gluten-free, ditched dairy — and you still can’t figure out what’s behind your symptoms. Meanwhile, generic dietary advice burns through months of your time while inflammatory reactions keep hammering your gut health.
Food sensitivity testing analyzes your blood for IgG antibody responses to specific foods, uncovering delayed inflammatory reactions that conventional allergy panels flat-out miss (NIH). Our panel shows exactly which foods trigger your immune system — a clear roadmap instead of endless guesswork.

Are Hidden Food Sensitivities Causing Your Unexplained Symptoms?
You’re doing everything right — organic produce, lean proteins, whole grains — and you still deal with bloating hours after meals, afternoon energy crashes, brain fog that won’t lift, and skin issues that flare without warning. Conventional doctors run standard allergy panels. They come back negative. And you’re left with zero answers.
Here’s the thing: the problem isn’t that you’re eating unhealthy foods. It’s that your immune system has developed sensitivities to foods you eat regularly. These delayed inflammatory responses create chronic symptoms that stick around because you keep consuming trigger foods without realizing it. Our food sensitivity testing pinpoints your specific triggers through IgG antibody analysis, giving you the clarity to make dietary changes that actually matter.
What Is Food Sensitivity Testing and How Does It Work?
Food sensitivity testing is a blood-based analysis that measures IgG antibody levels against specific foods to reveal delayed immune responses contributing to chronic inflammation and symptoms (NIH). Unlike immediate allergic reactions — the kind that happen within minutes — food sensitivities trigger inflammatory responses hours or even days after you eat (NIH). That delay makes them nearly impossible to identify without testing.
When you eat a food your immune system has developed sensitivity to, your body produces IgG antibodies as part of an inflammatory response (NIH). Those antibodies bind to food proteins, forming immune complexes that circulate through your bloodstream and activate inflammation across various tissues (NIH). The result? Digestive issues, fatigue, brain fog, skin problems — sometimes all at once.
Our testing analyzes your blood sample for elevated IgG antibody levels against a panel of over 90 common foods spanning all major categories: dairy, grains, proteins, vegetables, fruits, nuts, seeds, and common additives (NIH). Higher antibody levels point to stronger immune reactions. We rank severity — mild, moderate, or severe — so we can prioritize which foods to pull first.
We’ve simplified the process as much as possible. At our Spring location, we perform a quick blood draw that takes under 10 minutes. You’ll get your full results within 7–10 business days, followed by a detailed consultation where we walk through your findings and build your personalized elimination protocol.
What's the Difference Between Food Allergies, Intolerances, and Sensitivities?
Food allergies, intolerances, and sensitivities are three distinct responses — immune and digestive — that produce different symptoms through different mechanisms. Understanding these differences explains why standard allergy testing misses the chronic symptoms dragging you down.
True food allergies involve IgE antibodies and trigger immediate, potentially life-threatening reactions within minutes to two hours (NIH). Think histamine release: hives, throat swelling, breathing difficulty, anaphylaxis. Common culprits include peanuts, shellfish, and tree nuts.
Food sensitivities work through a completely different pathway. Your immune system produces IgG antibodies against specific food proteins, creating inflammatory immune complexes that circulate for hours or days before symptoms show up (NIH). By the time you notice the bloating or fatigue, you’ve already eaten dozens of other foods. That’s exactly why elimination diets alone rarely work — and why the inflammatory nature of IgG responses ties into so many chronic conditions.
Food intolerances? Different story entirely. These involve enzyme deficiencies, not immune responses. Lactose intolerance happens when your body doesn’t produce enough lactase to break down milk sugar. You get digestive symptoms, but there’s no antibody production or inflammatory cascade involved.
What Symptoms Are Associated with Food Sensitivities?
Food sensitivities are associated with chronic symptoms including persistent digestive issues, neurological symptoms like brain fog and headaches, unexplained fatigue, skin conditions, and systemic inflammation that hasn’t responded to conventional approaches.
Bloating that gets worse as the day goes on, alternating constipation and diarrhea, gas, abdominal discomfort, IBS-type presentations — these are classic. Trigger foods spark an inflammatory response that disrupts your intestinal lining and throws off normal digestive function.
The inflammatory cytokines produced by food sensitivity reactions also hit cognitive function hard. Difficulty concentrating, poor memory, mental fatigue, brain fog that just won’t clear. Chronic headaches and migraines correlate with food sensitivities too — particularly reactions to dairy, gluten, eggs, and certain preservatives.
And the fatigue? Ongoing immune activation from daily exposure to trigger foods drains your energy reserves. Your body redirects resources toward managing inflammation instead of cellular energy production. That’s why you feel wiped out despite sleeping eight hours — and why eliminating trigger foods often produces dramatic energy improvements within 2–4 weeks.
Eczema, acne, rashes, general skin inflammation — these frequently improve when underlying food sensitivities are addressed. Your skin functions as an elimination organ, and inflammatory immune complexes often show up as visible reactions there first.

How Do We Integrate Food Sensitivity Testing with Functional Medicine?
We integrate food sensitivity testing into a full functional medicine approach that addresses root causes, supports gut healing, and builds sustainable dietary changes. You don’t just get test results from us — you get a complete roadmap for reducing inflammation and improving your health.
Your results tell us which foods trigger inflammatory responses. But we take it further. We analyze those results alongside your complete health history, current symptoms, lifestyle factors, and nutritional needs. That context lets us build a personalized elimination protocol that removes trigger foods without leaving nutritional gaps.
Here’s something most people don’t realize: food sensitivities often develop because of underlying gut health issues — increased intestinal permeability, dysbiosis, chronic inflammation sensitizing your immune system. We address these root causes while you eliminate trigger foods, supporting your gut’s natural healing through targeted nutritional support and lifestyle changes. This is why many of our patients can eventually reintroduce foods after a healing period. The testing alone doesn’t get you there — the whole approach does.
How Should You Prepare for Your Food Sensitivity Test?
You should continue eating your normal diet before food sensitivity testing, including foods you suspect may be problematic — accurate IgG antibody detection requires recent exposure to trigger foods.
We get this question constantly: ‘Should I cut out the foods I think are causing problems before my test?’ No. If you’ve avoided a food for several weeks, your IgG antibody levels may have dropped enough to skew results. Keep eating your typical diet for at least two weeks before testing.
Your appointment at our Spring, TX location involves a simple blood draw — under 10 minutes, no fasting required. Bring a list of current medications and supplements, since some immune-modulating medications can affect results.
Results typically come back within 7–10 business days. Once they’re in, we schedule your follow-up consultation to review everything in detail and map out your personalized protocol.
What Happens After You Get Your Food Sensitivity Test Results?
After receiving your results, we guide you through a structured elimination protocol — removing trigger foods for 4–6 weeks, then systematically reintroducing them to determine your individual tolerance levels. This process allows gut healing while revealing which foods you can eventually bring back.
Results categorize foods by severity: mild, moderate, and severe based on IgG antibody concentrations. We tackle severe and moderate reactions first since those drive the most significant inflammation. Focusing on high-impact eliminations keeps the protocol manageable rather than overwhelming.
The elimination phase runs 4–6 weeks — enough time for inflammatory markers to drop and symptoms to improve. During this window, you completely avoid identified trigger foods while maintaining a nutritious, varied diet built around foods that tested negative.
Then comes systematic reintroduction. One food at a time, monitoring for symptom recurrence. This reveals whether you’ve developed tolerance after the healing period or whether certain foods need longer-term avoidance.
Our goal isn’t permanent food restriction. It’s a sustainable dietary pattern that minimizes inflammation while keeping variety and enjoyment intact. After reintroduction, you’ll know your individual tolerance levels and exactly which foods to avoid — permanently or temporarily.
Who Should Consider Food Sensitivity Testing?
Food sensitivity testing is most beneficial for people experiencing chronic unexplained symptoms despite conventional medical evaluation, those with digestive disorders like IBS, people with autoimmune conditions, and anyone whose symptoms haven’t budged with standard elimination diets.
If you’ve been diagnosed with IBS or deal with chronic digestive symptoms without a clear cause, food sensitivities may be a significant contributing factor. Research suggests that a substantial percentage of IBS patients show elevated IgG antibodies to multiple foods, and many experience symptom improvement when trigger foods are removed.
Patients with autoimmune conditions often benefit because ongoing exposure to trigger foods maintains systemic inflammation. Food sensitivity testing doesn’t address autoimmune disease directly, but reducing dietary inflammation supports overall immune regulation.
The most frustrated patients we see? People eating exceptionally healthy diets who still feel terrible. When you’re already avoiding processed foods, eating organic, and following nutritional best practices, food sensitivities become the most likely explanation. Testing provides the missing piece.

Frequently Asked Questions About Food Sensitivity Testing
You've got questions, we've got answers.
Don’t see what you’re looking for?
How accurate is IgG food sensitivity testing?
IgG food sensitivity testing measures antibody levels with high laboratory accuracy, though individual responses to elimination vary. Studies show that patients who eliminate high-reactivity foods based on IgG testing often experience significant symptom improvement, though results depend on compliance and underlying health factors.
Can I do food sensitivity testing at home with a mail-in kit?
While mail-in kits exist, clinical blood draws at our Spring, TX location provide proper sample handling and faster turnaround. In-office testing maintains sample integrity and lets us review your medical history during collection — context that genuinely improves how we interpret your results.
How long does it take to see results after eliminating trigger foods?
Most patients notice initial improvements within 2–3 weeks, with more significant changes by 4–6 weeks. Timeline varies based on reaction severity, how many foods you’re eliminating, and your body’s natural healing capacity.
Will I have to avoid my trigger foods forever?
Not necessarily. Many patients reintroduce foods successfully after a 4–6 week elimination period, especially when they’re simultaneously addressing underlying gut health. Some foods may require permanent avoidance; others can be consumed occasionally without triggering symptoms.
Does insurance cover food sensitivity testing?
Coverage for IgG food sensitivity testing varies by provider and plan. We recommend contacting your insurance company directly to verify. Our team can provide documentation and coding information to support your claim if your plan offers reimbursement.
