Abstract
The radioallergosorbent test (RAST) is one of useful method in detecting specific IgE antibodies in serum. It is an objective, in vitro test with the advantage of low risk. It was widely used as a routine check in the allergic patients now.
In order to prove the existance of the specific IgE antibody in nasal tissue, 8 cases of nasal polyp and 6 cases of nasal mucosa were checked with tissue RAST (t-RAST) in our studies.
The result of t-RAST was discussed and compared with nasal smear, skin test and serum RAST. In cases of polyps, t-RAST showed the same or somewhat higher level than the serum RAST. In 2 cases of nasal polyp which were negative in serum RAST, we proved positive results in t-RAST of polyp. T-RAST and serum RAST revealed the same score in 5 cases of nasal mucosa with allergic rhinitis. Conclusively, tissue RAST is one of the useful methods in diagnosis of nasal allergy.
