The Allergy Skin Test Procedure
Before you get an allergy skin test, it’s good to know what happens. This test helps find out what allergens cause reactions. We’ll explain how to prepare, the test itself, and what happens next.
Preparation Guidelines
Some medicines and things can affect the test results. Antihistamines, for example, can hide the skin’s reaction. Talk to your doctor about your medicines to make sure you’re ready.
Also, tell your doctor about any allergies or conditions you have. This helps make the test more accurate for you.
The Testing Process
The test puts a small amount of allergen on your skin. It’s done by applying a drop and then pricking the skin with a lancet. This lets the allergen get into your skin and cause a reaction if you’re allergic.
The test is quick and simple. You can test many allergens at once by using different drops and pricks.
The 15-20 Minute Observation Period
After the test, you’ll wait 15-20 minutes to see how your skin reacts. A wheal and flare response means you’re allergic. The size of the wheal tells how severe the allergy is.
