Description
IgG + IgE Combined Food & Allergy Panel
This combined panel simultaneously measures both IgG-mediated delayed food reactions and IgE-mediated immediate allergic reactions in a single blood draw — providing the most complete picture of food immune reactivity available. Many patients have both IgE and IgG reactions to the same or different foods, and understanding both is essential for a comprehensive elimination and reintroduction protocol.
What Is Tested:
- IgG Food Reactivity (200+ foods): Delayed-type immune reactions causing chronic symptoms 2–72 hours after consumption — the primary driver of food-related inflammation, gut symptoms, skin conditions, and mood disturbances
- IgE Food & Environmental Allergies (150+ allergens): Immediate-type allergic reactions — anaphylaxis, urticaria, asthma, rhinitis, and eczema triggers — appearing within minutes to 2 hours
Why Order Both Together:
- Patients with IgE allergies often also have IgG sensitivities to other foods not identified by allergy testing alone
- Foods that are IgE-negative may still drive chronic inflammation via IgG
- Eliminates the need for two separate blood draws
- Most cost-effective way to get both reaction types assessed comprehensively
Sample Type:
