Allergy skin testing is a simple, painless way to learn if you are suffering from allergies. About 8 out of 10 people who have allergic rhinitis (nasal itching, stuffiness, or congestion) go undiagnosed and untreated. An allergy test can identify the cause(s) of your allergies and put you on a path to treatment and relief. An allergy skin test can be performed quickly in the comfort of your doctor’s office. This test does not hurt and does not use a needle. It involves placing a small drop of several different allergens on or just under the surface of your skin, and measuring your body’s responses.
