Allergological diagnostic test applying allergens to the patient's skin to test for allergies.
Diagnostic exam using small amounts of allergens applied to the skin to identify the responsible allergen for an allergic reaction.
The skin test (or prick-test) is the most common and cost-effective allergological test. Small amounts of allergen extracts are applied to the skin, then the skin is lightly pricked with a lancet to allow the allergen to penetrate. If the patient is allergic, a local reaction appears (redness and swelling) within a few minutes. The result is usually visible in 15 to 20 minutes. The test can quickly identify multiple allergies simultaneously, making it an efficient diagnostic tool. A positive reaction indicates IgE-mediated sensitization, although a positive result does not always guarantee a clinical allergy.
Diagnostic tool to identify responsible allergens causing immune reactions and guide avoidance measures.
Consult a qualified allergist to perform and interpret tests. Stop certain antihistamines 5 to 7 days before the test, as they may skew results. Keep a food diary to aid in interpreting results and identifying food reactions.
The skin test is a simple and reliable diagnostic method for precisely identifying responsible allergens.
