Abstract
Total immunoglobulin E (IgE) in the serum and nasal secretion was determined by the Paper disk radioimmunosorbent test (PRIST) in 26 patients with allergic rhintitis. In samples of nasal secretion collected without provocation, the mean value of IgE was 128±207IU/ml. The average value of the serum IgE was appoximately four times as high, but there was no significant correlation between serum and nasal secretion IgE. The amount of IgE in nasal secretion was larger than we had expected. If enough nasal secretion can be collected, RAST can be used to determine antigen more accurately.
