Onion (f48) IgE details
What Onion (f48) IgE shows
This test measures IgE antibodies directed at proteins in onion, a vegetable used raw and cooked in many dishes. It is used to check for allergic sensitization when you have had symptoms such as itching, hives, swelling or stomach upset after eating or handling onion. A positive result shows that your immune system has made IgE to onion, and higher levels make a true allergy more likely. Onion is related to garlic, leek and chives, and handling raw onion can also irritate the skin and eyes without any allergy. A positive result shows sensitization, not necessarily allergy, so it needs to be read against your symptoms and history.
