Which testing method is better?

Allergists consider skin tests more reliable, precise, convenient and less expensive than blood tests. Innovations in testing technology have made the old radioallergosorbent test (RAST) obsolete. The new methods provide accurate and precise measurements of allergy antibody levels in the blood, and seem particularly useful for identifying some types of food allergies. Both methods are available, and whether one is more appropriate than the other depends on the patient's specific circumstances.

                Allergy tests alone do not confirm or refute the presence of allergies. All test results, regardless of type, require a trained specialist to interpret the results in conjunction with the patient's medical history and examination.
