Skin tests involve exposing the skin to different allergens to check for reactions. These examinations help identify substances that cause allergic symptoms when touched, inhaled, or ingested. They are quick, often taking 20 to 40 minutes.
Two Types of Skin Tests
There are two common skin test types that doctors use to diagnose allergies.
Prick or Scratch Test
During this procedure, small amounts of allergens are applied to your skin. A thin needle is then used to prick or scratch the surface, allowing the substance to enter the skin. Within 15 minutes, any reaction, such as redness or raised spots (wheals), will appear. This test mainly checks for airborne allergens, food allergies, or penicillin allergies. If a positive reaction occurs, the allergen responsible for the symptoms is identified.
Intradermal Test
This involves injecting some amount of an allergen just below the skin's surface using a fine needle. This test is often done when the prick test doesn't provide precise results or for specific allergies, such as reactions to insect venom or certain medications. After the injection, the area is observed for a reaction within 10-15 minutes. If no reaction occurs, a stronger dose of the allergen is injected for further testing. Though the test may take up to 90 minutes, it is relatively painless and provides more detailed results than a prick test.
Conclusion
Your healthcare provider will select the right test by finding out your skin type. Allergy tests can pinpoint triggers behind reactions, from mild to severe symptoms. Getting a health insurance plan can help cover treatments, ensuring your well-being.
