Black Pepper (f280) IgG4 details
What Black Pepper (f280) IgG4 shows
This test measures IgG4 antibodies to black pepper, a spice found in many everyday dishes. IgG4 is a subclass of IgG antibodies that the immune system commonly makes to foods you eat regularly, so food IgG4 testing is used by some practitioners to look at your immune response to foods in your diet. A higher result generally means you have been exposed to black pepper, often through regular eating, while a low result may reflect little recent intake. Food IgG4 reflects exposure and tolerance rather than allergy, its link to symptoms is debated, and it is not a test for a true food allergy, which is assessed with IgE.
