Unlike IgE food allergy tests that detect immediate allergic reactions, this IgG panel identifies delayed food sensitivities that can cause symptoms hours or days after eating. The panel tests IgG antibodies against 96 of the most commonly consumed foods including dairy, grains, fruits, vegetables, meats, seafood, nuts, and spices. Elevated IgG responses may be associated with chronic symptoms like bloating, gas, fatigue, brain fog, joint pain, headaches, and skin conditions such as eczema. Results can guide an elimination diet to identify trigger foods. This is the same type of comprehensive food sensitivity testing offered by companies like Everlywell and Viome, performed at a clinical laboratory.
