Abstract

A coagglutination test for detection of group A streptococci in throat samples was evaluated in a multicentre study and found to be about 95 % sensitive when applied to swabs taken from symptomatic patients which yielded more than 100 colonies per plate on culture. The sensitivity of the test dropped significantly when it was applied to swabs giving fewer than 100 colonies on culture. The specificity of the test was high regardless of colony count on conventional media.
