The terms food allergy and food sensitivity are widely confused and often wrongfully used interchangeably. A true food allergy (type I hypersensitivity or immediate reaction) is usually mediated by an IgE-specific antibody. The Vibrant Food Sensitivity test measures IgG and IgA antibodies, which are more indicative of a food sensitivity (type 2, 3, or 4 hypersensitivities, or delayed reactions). For a full explanation on the difference between food immunoglobulins please see the Food Immunoglobulins handout.
Please note: Food Allergy (IgE) testing is available through Vibrant, but is separate from Vibrant's Food Sensitivity and Food Additives tests.
