Quick antigen testing with immediate results.

Allergy and food sensitivity testing measures your immune system's response to specific substances. IgE-mediated allergy tests detect true allergies — immediate immune reactions that can cause hives, swelling, breathing difficulty, or anaphylaxis. IgG food sensitivity tests measure delayed immune responses that may contribute to chronic symptoms like bloating, fatigue, headaches, or skin issues hours to days after eating trigger foods. While IgE allergy testing is well-established in clinical medicine, IgG food sensitivity testing is a growing area that many functional and integrative practitioners use as a guide for elimination diets. These tests can help identify triggers that are difficult to pinpoint through observation alone.
