Precipitating antibodies against pigeon bloom antigens as a specific and sensitive measure of pigeon exposure.
Precipitating antibodies against pigeon bloom antigen and pigeon serum were evaluated as a measure of pigeon exposure in 62 male pigeon breeders compared with 40 unexposed control subjects. We found a combination of highly antigenic bloom extract and a sensitive counter current immunoelectrophoresis suitable for clinical estimation of pigeon exposure. The sensitivity of the test was 86% in never-smokers and 73% in smokers at the 98% specificity level. Smoking significantly reduced the humoral immune response to both antigens.
