Skin allergy tests identify allergens causing allergic reactions by exposing the skin to potential allergens and observing the reaction.
Common types include patch tests, prick tests, and intradermal tests, each used to detect different types of allergic reactions.
Small amounts of allergens are applied to adhesive patches placed on the skin. Patches are worn for 48 hours to detect delayed reactions.
Allergens are applied to the skin's surface using a small needle to prick through the allergen drops. Reactions are observed within 15-20 minutes.
Allergens are injected just under the skin’s surface. This test is more sensitive and is often used for testing suspected environmental allergens.
Avoid antihistamines and certain medications before testing, as they can interfere with results. Consult your doctor for specific preparation instructions.
Always consult an allergist or dermatologist for accurate testing and interpretation. They provide professional guidance on managing allergies based on test results.
Regular follow-ups with your healthcare provider may be necessary to adjust treatment plans or test for additional allergens if symptoms persist.
