Agreement between radioallergosorbent test and skin test.
A total of 4,260 RAST results were compared with the same number of prick and intracutaneous skin test results. Intracutaneous test was done only when the prick test was negative. The mean agreement between positive RAST and positive prick test was 81.3% for five grasses, 45.1% for seven weeds, 42.2% for two trees, 42.6% for two molds, and 45.8% for two environmental antigens. The mean agreement between positive RAST and positive intracutaneous test ranged from 0 to 4.9% for the same antigens.
