Types of allergy tests

To identify what kind of allergy an individual is suffering from, a health professional conducts an allergy test. Allergy tests can be various types depending upon the purpose they are serving:

Patch Test: This test cause contact dermatitis, a type of skin reaction that can cause itchy, inflamed skin. During this test, small amounts of potential allergens are carefully applied to patches. These patches are then placed on the skin. These are then checked at intervals of time like in 48, 72, and 96 hours. This should be enough time for the reaction from the allergen to occur.

Skin Prick Test: This test is prevalent to diagnose allergies from pollen, mold, dust mites, etc and is usually the first step to diagnosis of several allergies. In this test, a small amount of allergen, like environmental allergens, pet allergens, or food allergens are applied and pricked to the skin of the forearm or back. This is done to let allergens enter the skin’s surface and see if there is some reaction. If present, the reaction typically manifests as a small, raised bump similar to a mosquito bite, indicating an immune response to the allergen in question.

Blood Test to check for IgG: Blood is drawn to check the presence of antibodies to some specific allergens. It is useful for people with skin problems as skin prick tests or patch tests can not be performed on them.
