Walnut Food (Juglans spp.) IgG4 details
What Walnut Food (Juglans spp.) IgG4 shows
This test measures IgG4 antibodies to walnut nut proteins in your blood. IgG4 food tests are sometimes ordered to look at possible food sensitivities that are not immediate allergies. A higher result generally reflects exposure — your immune system has met walnut through your diet — and IgG4 is often associated with tolerance rather than an allergic reaction. A low result usually means little recent exposure. The link between food IgG4 levels and symptoms is debated, and this result does not diagnose a tree nut allergy, which can be serious and is assessed with IgE testing and your history.
