Correlation of RAST and provocation tests for diagnosing allergic asthma and rhinitis
Abstract
252 bronchial (BPT) and 346 nasal (NPT) provocation tests were done. A positive RAST coincided with a positive BPT in 81% and a positive NPT in 82% of the cases. When RAST was negative the BPT's were positive in 33% and NPT's in 54% of trials. Contrary to the NPT's the RAST and the BPT's agreed well in different allergen groups, excepting mold provocation.
