Bell Pepper IgG4 details
What Bell Pepper IgG4 shows
Bell pepper is a sweet pepper eaten raw and cooked in many dishes. This test measures IgG4, a subclass of IgG antibodies, to bell pepper proteins in your blood. Unlike IgE, which drives classic food allergy, IgG4 to foods is common in healthy people and tends to rise with regular eating, so it mainly reflects exposure. A higher result usually means you eat bell pepper often. Whether food IgG4 explains symptoms such as bloating or headaches is debated, and major allergy organizations do not recommend it for diagnosing food intolerance. It does not show a food allergy.
