What Are the Different Types of Allergy Testing?
Allergy testing is usually done by testing the skin or the blood for the presence of a reaction to an allergen. There are three principal types of allergy testing used in modern medicine: skin testing, elimination testing, and radioallergosorbent testing (RAST). Tests done on the skin are more common than lab work on blood, because skin testing is less costly and somewhat more reliable than a blood test. Other testing methods besides those above exist as well, such as the astonishingly simple, yet effective methods used by naturopathic physicians.
