érzékenységvizsgálatot

Érzékenységvizsgálat, also known as allergy testing or skin prick test, is a medical procedure used to diagnose allergies. It involves introducing small amounts of potential allergens under the skin and observing the reaction. The most common method is the skin prick test, where a small amount of the allergen is placed on the skin using a lancet or needle. If the person is allergic to the substance, a raised, red, itchy bump will appear within 15-20 minutes. The results are typically read by a healthcare professional and can help in identifying specific allergens.

Another method is the intradermal test, which is similar but uses a larger amount of allergen and is more sensitive. Blood tests, such as the RAST (Radioallergosorbent Test) or ImmunoCAP, can also be used to detect specific IgE antibodies in the blood, indicating an allergy. These tests are often used in conjunction with skin tests to confirm or rule out allergies.

Érzékenységvizsgálat is commonly used to diagnose allergies to common substances like pollen, dust mites, and pet dander. It can also be used to identify allergies to medications, foods, and other environmental factors. The procedure is generally safe and well-tolerated, but it may cause minor reactions such as redness, itching, or swelling at the test site. In some cases, a local anesthetic may be used to minimize discomfort.

The results of an érzékenységvizsgálat can guide treatment and help in avoiding triggers. However, it is important to note that the test may not detect all allergies, and false positives or negatives can occur. Therefore, it is often used as part of a comprehensive evaluation by an allergist or immunologist.
