An allergietest is a medical procedure used to identify substances, known as allergens, to which a person's immune system reacts abnormally. These reactions can manifest as a variety of symptoms, including skin rashes, respiratory problems, digestive issues, and in severe cases, anaphylaxis. Allergy testing helps pinpoint the specific triggers for these allergic responses, allowing for appropriate management and avoidance strategies.

There are several common types of allergy tests. Skin prick testing, also known as puncture or scratch testing, involves introducing small amounts of common allergens to the surface of the skin, typically on the forearm or back. If an allergic reaction occurs, a small, itchy bump will appear at the site of the allergen. Blood tests, such as the IgE antibody test (RAST or ImmunoCAP), measure the level of specific antibodies in the blood that are produced in response to particular allergens. Patch testing is used to diagnose contact dermatitis and involves applying suspected allergens to the skin under a patch for 48 hours, with the reaction assessed afterward.

The results of an allergietest are interpreted by a healthcare professional, often an allergist or immunologist. Based on the findings, they can recommend treatments such as allergen avoidance, medications like antihistamines or corticosteroids, and in some cases, immunotherapy (allergy shots) to desensitize the immune system to specific allergens. Accurate diagnosis through allergy testing is crucial for improving the quality of life for individuals suffering from allergic diseases.
