Grapefruit (f209) IgE details
What Grapefruit (f209) IgE shows
Grapefruit is a citrus fruit eaten fresh and as juice, and its peel and extracts are used in flavorings. This test measures IgE antibodies specific to grapefruit proteins to check for allergic sensitization to this fruit. A positive result can help explain symptoms such as mouth itching, hives, swelling or digestive upset after eating grapefruit. Sensitization to one citrus fruit can overlap with others, such as orange or lemon. A positive result shows sensitization, not necessarily allergy, so it needs to be read against your symptoms and history. This test is unrelated to grapefruit's well-known interactions with some medicines.
