The Challenge
When Food Becomes the Problem You Cannot See
Understanding Hidden Immune Reactions
Many patients eat what they believe is a healthy diet yet continue to experience bloating, brain fog, joint pain, or chronic fatigue that no amount of dietary adjustment seems to resolve. Unlike immediate allergic reactions that produce hives or swelling within minutes, food sensitivities involve delayed immune responses that can manifest hours or even days after eating. This delay makes identifying the actual triggers nearly impossible through observation alone, leaving patients frustrated and cycling through ineffective elimination attempts without clinical guidance.
Cyrex food sensitivity testing measures both IgG and IgA antibody responses to up to 180 food antigens in raw, cooked, and processed forms, eliminating the guesswork from dietary protocols. Our staff analyzes your complete reactivity profile and creates a targeted elimination and reintroduction protocol that addresses the root causes of your symptoms. Rather than broad dietary restrictions, this precision approach removes only the foods your immune system is actively reacting to, preserving nutritional diversity while resolving chronic inflammation and restoring gut health and digestive function.
What Is Food Sensitivity Testing?
The Science of Immune Food Reactivity
Food sensitivity testing through Cyrex Laboratories uses enzyme-linked immunosorbent assay (ELISA) technology to measure IgG and IgA antibody responses to food proteins. Unlike standard allergy testing that measures only IgE-mediated immediate reactions, Cyrex panels detect delayed-type immune responses responsible for chronic inflammation and systemic symptoms that may not appear for 24 to 72 hours after consuming a reactive food.
How Food Sensitivity Testing Works
The Cyrex Array 10 panel screens up to 180 food antigens in raw, cooked, modified, and processed forms. This distinction matters because research by Vojdani (PMID: 19435515) demonstrated that antibodies against cooked food antigens were three to eight times higher than reactions to raw forms in 31% of patients studied. By testing both preparations, Cyrex reduces the possibility of missed sensitivities that occur when labs test only raw food antigens. The panel reports 97% sensitivity and 98% specificity for detecting food-specific immune reactivity, making it one of the most reliable tools available for functional medicine practitioners.
What Happens During Food Sensitivity Testing
The process begins with a venous blood draw at our Port Charlotte clinic, performed by our trained medical assistant Janette. Your sample is shipped directly to Cyrex Laboratories for comprehensive IgG and IgA analysis. Results typically return within two to three weeks, at which point our staff reviews your complete reactivity profile and designs a personalized nutrition counseling protocol.
Food Sensitivity Test Results and Duration
Most patients begin noticing improvements in digestive symptoms, energy levels, and inflammatory markers within four to six weeks of following their Cyrex-guided elimination protocol. The elimination phase typically lasts 90 days, after which our staff guides a structured reintroduction process to identify which foods can safely return to your diet and which require long-term avoidance.

Who Is a Good Candidate for Food Sensitivity Testing?
Finding Your Path to Dietary Clarity
Food sensitivity testing benefits individuals with chronic symptoms unresponsive to conventional treatment, especially when dietary triggers are suspected. Many patients with hormonal imbalance or persistent digestive complaints discover that food-driven inflammation has been disrupting their metabolic and immune function for years.
Ideal Candidates for Food Sensitivity Testing
- Adults with persistent bloating, gas, diarrhea, or constipation not explained by other diagnoses
- Patients with IBS symptoms who have not improved with standard dietary changes or medications
- Individuals experiencing unexplained fatigue, brain fog, or poor concentration despite adequate sleep
- Those with chronic joint pain, skin eruptions, migraines, or headaches with suspected dietary triggers
- Patients with autoimmune conditions seeking to identify food-driven immune activation
- Anyone committed to following a structured elimination and reintroduction protocol under clinical guidance
Who Should Wait or Avoid Food Sensitivity Testing
- Patients currently taking immunosuppressant medications or corticosteroids (must be clear for at least 60 days to avoid false-negative results)
- Individuals who have been on a strict elimination diet for an extended period (antibody levels may not reflect true reactivity)
- Children under the age of two (immune system still developing food tolerance)
- Patients with severe anemia or blood disorders that contraindicate venipuncture
Our staff evaluates each patient's medical history, current medications, and symptom profile during the initial consultation to determine whether Cyrex testing is the appropriate diagnostic step or whether a GI-MAP test may be a better starting point.

Risks and Side Effects
What to Know
Blood Draw Side Effects
The blood draw itself carries minimal risk. Patients may experience brief discomfort at the puncture site, minor bruising, or slight soreness that typically resolves within one to two days. Rare complications include dizziness or lightheadedness during the draw, which can be minimized by staying hydrated beforehand.
Elimination Phase Considerations
Some patients experience temporary adjustment symptoms during the first one to two weeks of their elimination protocol, including mild headaches, changes in energy levels, or digestive shifts as the body adapts to the dietary changes. These symptoms typically resolve within seven to 14 days and indicate the immune system is responding to the reduced antigenic load.
Safety and Clinical Oversight
Our staff monitors all patients throughout the elimination and reintroduction phases to ensure nutritional adequacy and address any concerns. The Cyrex Array 10 is a diagnostic laboratory test - not a treatment - so the primary safety considerations relate to proper interpretation and protocol implementation rather than the test itself. Patients on immunosuppressants should not discontinue medications without medical guidance.

Frequently Asked Questions About Food Sensitivity Testing
Your Questions Answered
01 What is the difference between a food allergy and a food sensitivity?
Food allergies involve IgE antibodies causing immediate reactions like hives, swelling, or anaphylaxis within minutes of exposure. Food sensitivities involve IgG and IgA antibodies that trigger delayed immune responses — symptoms such as bloating, fatigue, or joint pain may not appear for 24 to 72 hours, making them difficult to identify without laboratory testing.
02 How is the Cyrex test different from at-home food sensitivity kits?
Cyrex tests both IgG and IgA antibodies against raw and cooked food forms with 97% sensitivity and 98% specificity. Most at-home kits test only IgG against a limited number of raw food antigens, which can miss sensitivities that appear only when foods are cooked or processed. Cyrex also provides clinical-grade reporting that Dr. Korman uses to design a precise elimination protocol.
03 Do I need to fast before my blood draw?
No fasting is required. Continue eating your normal diet before testing so antibody levels accurately reflect your current food exposure and immune responses. Avoiding foods before the test could actually reduce detectable antibody levels and lead to missed sensitivities.
04 Will I have to avoid my reactive foods permanently?
Not necessarily. Dr. Korman designs a phased elimination and reintroduction protocol. After a 90-day elimination period, many foods can be carefully reintroduced while monitoring for symptom recurrence. Some high-reactivity foods may require longer avoidance, while moderate-reactivity foods often return to the diet successfully.
05 Can food sensitivity testing help with IBS symptoms?
Research supports IgG-guided elimination diets for IBS management. A randomized controlled trial (PMID: 15361495) demonstrated a 10-26% greater reduction in IBS symptom severity compared to sham diet. Dr. Korman often combines Cyrex testing with GI-MAP testing to address both food reactivity and gut microbiome imbalances in patients with IBS.
06 Can I combine food sensitivity testing with other services?
Yes. Dr. Korman frequently pairs Cyrex testing with GI-MAP testing to evaluate both food immune reactivity and gut microbiome health simultaneously. This combination provides the most comprehensive picture of digestive function and is especially valuable for patients with chronic gut health concerns or autoimmune conditions.
07 How long does it take to get results?
Results typically return from Cyrex Laboratories within two to three weeks after your blood draw. Dr. Korman then schedules a detailed results review appointment to walk you through your reactivity profile and begin designing your personalized elimination protocol.
08 Is food sensitivity testing covered by insurance?
Cyrex testing is not typically covered by standard health insurance plans. However, patients with health savings accounts (HSAs) or flexible spending accounts (FSAs) may be able to use those funds. Contact our office at (941) 629-6700 to discuss payment options and panel pricing.
