title: Group A Streptococcus detection: office versus reference laboratory.
abstract: Clinical differentiation between a virus and beta-hemolytic streptococci as a cause of pharyngitis remains difficult. In the physician's laboratory, more rapid procedures using immunologic methods have replaced culture methods, traditionally requiring 2 to 3 days for identification of beta-hemolytic streptococci. Attention to the diagnostic sensitivity and specificity of these procedures will guide appropriate use.
