Are There Other Tests to Discover the Cause of Allergies?

26.03.2008 от M.V

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.
