Dietary Antigen Test (IgA & IgG)

Food Sensitivity Profile 1 - IgA and IgG

Vibrant Wellness Food Sensitivity test measures both IgA and IgG antibodies to 96 different food antigens (proteins).  Antigens are sourced from FDA-approved raw, organic foods. Vibrant Wellness reports IgA and IgG antibodies independently on our Food Sensitivity test.  Most other labs report these different antibodies as combined value.

The distinction between IgG vs. IgA antibodies is important. To look at both IgA and IgG antibodies to food antigens helps determine a food which may trigger an immune response through an IgG derived mechanism, while having absolutely no effect on IgA, or vice versa. See handout for more information
