What This Test Measures
- Total IgG reactivity to a broad menu of common foods, spices, and additives
- Serum sample (~1 mL) collected in-office by our phlebotomist
- Turnaround time of approximately 3 business days with a clear, color-coded report
- Technology: multiplex ELISA with nano-bead methodology to reduce cross-reactivity and improve analytical precision
- Performed in CLIA-certified, CAP-accredited laboratory facilities
These specifications come directly from the lab’s test overview.
Why People Choose foodANALYZER Here
- You want a structured starting point for an elimination diet instead of trial and error
- You struggle with bloating, brain fog, headaches, skin flares, energy swings, or IBS-like symptoms and want data to guide a plan
- You’ve “cleaned up” your diet and still feel off, and you want to pair results with coaching rather than a generic list of foods to avoid
We use your results to build a plan that fits your goals, training schedule, family meals, and social life. Access’s clinical content emphasizes IgG testing for delayed reactions that may contribute to ongoing digestive complaints, which is exactly where a targeted elimination makes sense.
What This Test Is Not
This is not an allergy test and does not diagnose IgE-mediated food allergy or anaphylaxis. Leading allergy societies advise against using IgG panels to diagnose allergy. We agree and use results in context with your history and, when needed, standard allergy evaluation.
How We Turn Results Into Daily Wins
- In-office blood draw at Peak by MD
- Result review and mapping of high, moderate, and low IgG foods with your symptoms and food log
- Targeted elimination of highest-reactive items for 3 to 6 weeks with a complete swap list and sample menus
- Gut support if indicated, based on your picture and, when appropriate, GI-MAP, micronutrient, or DUTCH data
- Guided reintroduction to confirm true triggers and liberalize your diet without unnecessary restrictions
- Long-term plan that balances performance, body composition, skin, and digestion
What You Receive
- A clear, color-coded report showing IgG reactivity to 200+ foods
- A 90-day blueprint that translates lab data into meals, grocery lists, and a simple schedule for elimination and reintroduction
- Optional integration with your PNOĒ RMR/VO₂, Styku 3D scan, hormone, and microbiome testing so nutrition aligns with metabolism, training zones, and recovery
Access provides extended food menus and example reports so you understand exactly how items are grouped and scored.
Who Is a Good Fit
- Persistent GI symptoms that have not responded to general diet changes
- Skin concerns such as acne, eczema, and hives that seem food-linked
- Headaches or fatigue patterns you suspect are diet-related
- Athletes or busy professionals who want a data-driven, time-efficient plan
Who Should Not Use This as Standalone
- Anyone with a history of anaphylaxis or immediate reactions to foods.
- Those needing evaluation for celiac disease, lactose intolerance, or histamine intolerance.
These conditions require different diagnostics and care pathways.
Frequently Asked Questions
The panel includes 200+ foods. Some versions approach ~286 antigens. We confirm your exact panel at the time of draw.
The assay is analytically robust and performed in a CLIA/CAP lab. Clinically, IgG is not diagnostic for allergy and is used to prioritize elimination trials alongside your history.
Typical turnaround is about 3 business days once the sample reaches the lab.
Coverage varies and is often limited for IgG panels. We are transparent about pricing and can provide a superbill upon request.
