Skin allergy test

Skin Allergy Test

A Skin Allergy Test (pronunciation: /skɪn ˈælərdʒi tɛst/) is a method used by medical professionals to identify the specific allergens that trigger an individual's allergic reactions.

Etymology

The term "Skin Allergy Test" is derived from the English words "skin" (the outer layer of the body), "allergy" (a hypersensitivity disorder of the immune system), and "test" (a method of examination).

Procedure

A Skin Allergy Test typically involves applying small amounts of common allergens to the skin using a tiny needle that barely penetrates the skin's surface. This is often performed on the forearm or back. The skin is then observed for signs of an allergic reaction, such as redness or swelling.

Types of Skin Allergy Tests

There are three main types of Skin Allergy Tests: the Prick Test, the Intradermal Test, and the Patch Test. Each test has its own specific procedure and is used to diagnose different types of allergies.
