Prunus persica Ab.IgE

This test detects IgE antibodies against peach (Prunus persica) proteins in your blood. A positive result suggests your immune system reacts to peaches. Peach allergies often occur as part of oral allergy syndrome, particularly in people with birch or grass pollen allergies, causing itching or swelling of the mouth when eating raw peaches. Cooking usually eliminates the reaction. This test distinguishes true peach allergy from pollen-related cross-reactivity and guides fruit consumption choices.
