Eosinophilic Test Local

Eosinophil tests are a series of allergy tests that include skin reaction, blood immunoglobulins, and other tests. One of the most common is the local Eosinophic test. This is a skin test that uses an antigen that causes an allergic reaction. This test is used to diagnose allergies to various substances such as foods, medications and even cosmetics.

A skin reaction to a topical Eosinophil test usually manifests itself as redness of the skin or blistering. It can be local, but can spread over a large area of ​​skin. The test uses an antigen in the form of a liquid or cream that is applied to the skin. Then a special dye is applied to the application site. After some time, the dye appears in color from white to bright red. If allergic reactions appear on the skin after the test, this indicates the presence of an allergy.

Eosinophils are cells of the immune system that are responsible for protecting against infections and allergies. In allergy tests, eosinophils may cause skin reactions. Immunoglobulin E is one of the most common markers of allergies and can increase antibody levels to various allergens.
