ALLERGY TESTING

. Posted in ALLERGIES

The next part of the exam will involve allergy testing to determine what allergies you may have, including ones you may not be aware of. This testing can be performed via various methods. An allergist typically uses the scratch or prick test as a primary tool for allergy testing. The intradermal skin endpoint titration test is believed by some to be more accurate. And more recently, technology has brought about blood testing called the radioallergosorbent test (RAST). Each of these tests has their strengths and weaknesses, and you should speak with your physician to decide which he or she feels is best for you.

Occasionally, a person is acutely aware of his or her allergies, but the testing is negative. This result is called a false negative. Most physicians will choose to continue to treat with allergy medicine, using the medication itself as a test. You may be asked to take the prescribed antihistamine for a time, then stop, and start again if symptoms get worse after stopping. If the antihistamine provides relief, then there is a good chance that you suffer from allergies even though your test was negative.
