Superior Technology
A combination of automated biochemistry and mass spectrometry technologies is utilized to provide a single comprehensive report.
These panels assess IgG, IgG4, and IgA reactions across varying numbers of common foods, allowing practitioners to scale food sensitivity evaluation based on clinical complexity and dietary exposure.
Assesses IgG, IgG4, and IgA reactions to 96 essential foods for food sensitivity evaluation and nutrition planning.
Assesses IgG, IgG4, and IgA reactions to 144 foods, offering broader food sensitivity evaluation and more comprehensive nutrition planning for complex cases.
Evaluates IgG, IgG4, and IgA responses to 240 foods, supporting in-depth food sensitivity analysis for patients with complex symptoms or diverse dietary exposures.
These panels assess IgG, IgG4, and IgA reactions to culturally specific foods, supporting accurate food sensitivity evaluation aligned with patients’ traditional dietary patterns.
Assesses IgG, IgG4, and IgA reactions to 96 commonly consumed Asian foods for culturally relevant food sensitivity evaluation and dietary planning.
Evaluates IgG, IgG4, and IgA responses to 96 Japanese food items to support precise food sensitivity assessment in patients following traditional Japanese diets.
Assesses IgG, IgG4, and IgA reactions to 96 Mexican foods, supporting food sensitivity evaluation tailored to traditional Mexican dietary patterns.
These panels assess IgG, IgG4, and IgA reactions to vegetarian foods, offering scalable food sensitivity testing for patients following plant-based diets.
Evaluates IgG, IgG4, and IgA responses to 96 vegetarian foods to support food sensitivity testing and nutrition planning in plant-based diets.
Assesses IgG, IgG4, and IgA reactions to 198 vegetarian foods, providing expanded coverage for comprehensive food sensitivity evaluation in vegetarian patients.
C3d is a stable marker of complement activation linked to IgG 1–3–mediated inflammatory food sensitivity reactions. When paired with IgG, IgG4, and IgA testing, it helps practitioners identify clinically relevant immune responses and prioritize dietary triggers.
C3d is a small protein made when the immune system activates the complement pathway to respond to foreign substances. It stays attached to immune complexes and helps signal when the immune system is reacting to something in the body.
C3d helps immune cells recognize and respond more strongly to substances the body sees as a threat. Because it shows active immune signaling, C3d is also used as a marker to identify inflammation and immune-driven conditions.
When the immune system reacts to a substance, C3 is broken down into smaller pieces, including C3d, which stays attached to that substance. This attachment helps activate immune cells and makes the immune response stronger and easier to detect.

US BioTek’s food sensitivity testing uses broad marker coverage to give practitioners a clearer view of food sensitivities. This reduces guesswork and supports more precise, personalized dietary decisions.
Turnaround time is important when working to find patients wellness success, at US BioTek we deliver test results in 7 business days.
Yes, all general and vegetarian food sensitivity panels come with Candida Albicans as an analyte marker. The 96 Asian and 96 Japanese panels do not include this marker.
No. We encourage all patients to consume their regular diet leading up to their food sensitivity and fasting prior to specimen collection is not required.
An elimination diet is a process of removing offending foods from your diet for a length of time to allow the body and immune system to heal. Following the elimination of the foods for the given period, foods with moderate sensitivity can be reintroduced on a 4-day rotation.
