When Healthy Foods Make You Feel Terrible
Hidden Reactions, Real Symptoms
You eat what you think is a balanced diet, yet you still feel bloated, sluggish, and inflamed. Unlike immediate food allergies that cause obvious reactions, food sensitivities create a delayed immune response that can take hours or even days to manifest. This makes it nearly impossible to connect symptoms like chronic headaches, joint pain, brain fog, eczema, and digestive distress to specific foods through elimination alone. Many patients spend years cycling through restrictive diets without clear answers.
Food sensitivity testing eliminates the guesswork by measuring your body's specific IgG and IgA antibody responses to dozens of common foods. With a single blood draw at RegalMed Clinic in Fort Myers, Dr. Farag can map your unique inflammatory triggers and create a personalized elimination and reintroduction plan. Rather than blindly cutting food groups, you receive a science-backed roadmap that reduces inflammation, resolves chronic symptoms, and helps you build a diet that truly supports your health.
What Is Food Sensitivity Testing?
Antibody-Based Diagnostic Analysis
Food sensitivity testing is a comprehensive blood-based diagnostic that measures your immune system's IgG and IgA antibody reactions to a wide panel of foods. Unlike IgE-mediated food allergies that cause immediate anaphylactic responses, food sensitivities involve delayed immune reactions that can trigger chronic inflammation throughout the body. The test identifies elevated antibody levels against specific food proteins, revealing which foods are activating your immune system even when symptoms don't appear for 24-72 hours after consumption.
At RegalMed Clinic, Dr. Farag uses advanced multiplex immunoassay technology to analyze your blood sample against 96 to 200+ food antigens simultaneously. Each food receives a reactivity score ranging from normal to high, allowing Dr. Farag to prioritize which eliminations will have the greatest impact. The science behind this testing is rooted in the understanding that chronic low-grade immune activation from food sensitivities contributes to intestinal permeability, systemic inflammation, and downstream conditions including IBS, migraines, eczema, and autoimmune flares.

Who Should Get Food Sensitivity Testing?
Find Out If Testing Is Right for You
Food sensitivity testing is ideal for adults and adolescents experiencing chronic, unexplained symptoms that haven't responded to standard treatments or general dietary changes.
Ideal Candidates for Food Sensitivity Testing
- Adults with chronic bloating, gas, or IBS-like symptoms despite a balanced diet
- Patients with recurring migraines or headaches without a clear trigger
- Individuals with persistent skin conditions such as eczema, acne, or rashes
- Those experiencing brain fog, fatigue, or mood changes related to eating
- Patients with autoimmune conditions seeking to reduce inflammatory triggers
- Anyone who has tried elimination diets without consistent results
Who May Not Be a Candidate
- Individuals with known IgE-mediated food allergies requiring epinephrine (testing does not replace allergy testing)
- Patients currently on high-dose immunosuppressive therapy that may alter antibody levels
- Those seeking diagnosis of celiac disease (requires specific celiac antibody testing such as CICA)
Dr. Farag evaluates your complete medical history during consultation to determine whether food sensitivity testing is the most appropriate diagnostic step for your symptoms.
What Happens During Testing
Blood Draw
A trained phlebotomist at Regal Med Clinic collects a small blood sample, typically completed in under 15 minutes.
Laboratory Analysis
Your sample is analyzed using multiplex immunoassay technology, measuring IgG and IgA antibody responses to 96-200+ food antigens.
Results Review
Dr. Farag walks you through your reactivity report, explaining high, moderate, and normal responses for each food tested.
Action Plan
You receive a personalized elimination protocol with a structured timeline for removing and reintroducing reactive foods.
Side Effects & Considerations
What to Know
Food sensitivity testing via blood draw carries minimal risk. The most common side effects are mild bruising or soreness at the draw site, which resolves within 1-2 days. Some patients may feel lightheaded briefly after the blood draw.
During the elimination phase, some patients experience temporary adjustment symptoms as their body adapts to dietary changes. These may include mild fatigue, headaches, or changes in bowel habits during the first 3-5 days of elimination, commonly referred to as a detox response. These symptoms are typically mild and self-limiting.
It is important to note that food sensitivity testing measures IgG/IgA antibody responses and is not a substitute for IgE allergy testing. Patients with known severe food allergies should continue to avoid those allergens regardless of sensitivity test results. Dr. Farag ensures that your elimination plan is nutritionally balanced and medically appropriate for your individual needs.

Food Sensitivity Testing FAQ
Answers to Your Questions
01 What is the difference between a food allergy and a food sensitivity?
Food allergies involve IgE antibodies and cause immediate, potentially life-threatening reactions like anaphylaxis. Food sensitivities involve IgG/IgA antibodies and produce delayed reactions such as bloating, headaches, fatigue, and skin issues that may appear hours or days after eating the trigger food.
02 How long does the blood draw take?
The blood draw itself takes approximately 5-10 minutes. Your total visit, including paperwork and consultation, is typically 15-30 minutes at our Fort Myers office.
03 Do I need to fast before food sensitivity testing?
Fasting is generally not required for IgG/IgA food sensitivity panels. However, Dr. Farag may provide specific preparation instructions based on your individual testing protocol.
04 How soon will I feel better after eliminating reactive foods?
Most patients report noticeable improvement in bloating, energy, and mental clarity within 2-4 weeks of beginning their elimination protocol. Full benefits typically emerge over 4-6 weeks as systemic inflammation decreases.
05 Can food sensitivities change over time?
Yes. After a structured elimination and gut healing protocol, many patients can successfully reintroduce previously reactive foods. Dr. Farag recommends retesting after 6-12 months to track changes in your antibody responses.
06 Is food sensitivity testing covered by insurance?
Most standard insurance plans do not cover food sensitivity testing. Regal Med Clinic provides transparent pricing during your consultation. Contact us at (239) 395-2434 for current rates.
