Carrot (f31) IgG4 details
What Carrot (f31) IgG4 shows
This test measures IgG4 antibodies to carrot, a common vegetable eaten raw and cooked. IgG4 is a subclass of IgG antibodies that the immune system often produces to foods you eat regularly, and some practitioners use food IgG4 panels to look at your immune response to your diet. A higher result generally means you have been exposed to carrot, 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.
