- Are There Other Tests to Discover the Cause of Allergies?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: Though my yearly allergies are very annoying, I just can't bring
- myself to those tests which involve all those needles being stuck into you.
- Are there any other tests that can help discover the cause of my problems, and
- perhaps lead to some treatments that can help?
-

- ANSWER: You can't escape getting stuck entirely, but one way of getting
- tested is more comfortable than another. The many injections or skin
- scratches used in traditional allergy testing can be replaced by one stick to
- draw a blood sample. One blood sample is all that is needed for RAST
- (radioallergosorbent test) to measure the body's response to allergens. RAST
- is a test conducted outside the body, or "in vitro" (it comes from the words
- for "glass," because of the methods that used test tubes for investigations
- and experiments).
- The traditional method of allergy testing involves injecting the skin,
- using a skin scratch technique, usually on the back, using many different
- allergens, and watching the body's reaction to each of them. This method,
- because it takes place in the body, is known as "in vivo" testing.
- RAST is more expensive than the customary scratch testing, but it is also
- more convenient, less time-consuming, and can tell us more precisely if a
- certain allergen is the cause of your allergy problem. You are lucky,
- however, as recent developments in new medications which are quite effective
- in controlling some of the annoying symptoms of summer allergies may be
- enough to help bring you the relief you are seeking.
