Allergy Testing in Greenville and Dallas TX

Allergy testing is a medical procedure used to determine if a person is allergic to a particular substance. Allergy testing can be performed using a skin prick test, blood test, or challenge test. Skin prick testing is the most common type of allergy test.

It involves placing a small amount of the allergen on the skin and then pricking the skin with a needle. If the person is allergic to the allergen, they will develop a raised, itchy bump on the skin. Blood tests and challenge tests are less commonly used and are usually only performed when skin prick testing is not possible or does not provide enough information.

Why do healthcare providers perform allergy tests?

Healthcare providers use allergy tests to identify substances that may trigger an allergic reaction in a person. Allergy tests may be performed using a skin prick test or a blood test. Skin prick tests are typically used to test for allergies to airborne substances, such as pollen or dust mites. Blood tests may be used to test for food allergies or allergies to substances that cannot be tested using a skin prick test, such as latex.
