Cedar- and cypress-pollen specific IgE antibody was measured by AIaSTAT, CAP-BAST, and MAST in 30 patients with pollenosis and 16 patients with bronchial asthma. The usefulness of each test was evaluated on the basis of the correlation of test results with clinical symptoms. The coefficient of correlation among all tests was 0.75 for cedar specific IgE antibody, and the relative correlation of test results and clinical symptoms was CAP-RAST ‹AIaSTAT › MAST. For cypress specific IgE antibody, the coefficient of correlation between the first two tests was 0.74, and the relative coincidence was ‹AIaSTAT › CAP-RAST. The antibody titer determined by AIaSTAT showed seasonal variations with a rise during the pollen season and a tendency to decrease thereafter.
