Understanding Allergy Tests: Skin and Blood Testing Explained
Allergy tests aim to identify specific allergens causing reactions. Two common types are skin tests and blood tests.
1. Skin Tests:
– Skin Prick Test: Small amounts of allergens are applied to the skin with a tiny needle. Pricking or scratching the skin allows the allergen to enter. If allergic, a small raised bump may appear. It’s not usually painful, but mild discomfort or itching may be felt.
– Intradermal Test: More sensitive than the skin prick test, this involves injecting a small amount of allergen just beneath the skin’s surface.
2. Blood Tests:
– RAST (Radioallergosorbent) Test: Measures specific IgE antibodies in response to allergens. A blood sample is sent to a lab for analysis. It’s less immediate than skin tests and is used when skin testing may not be suitable.
– Specific IgE Blood Test: Similar to RAST, this measures specific IgE antibodies in the blood in response to particular allergens.
Discussing concerns with your healthcare provider beforehand is crucial for addressing specific questions and understanding what to expect.
