KELLOGG Clinical Microbiology Laboratory, York Hospital, York, Pennsylvania 17405 INTRODUCTION There have been numerous conflicting reports concerning the most efficient culture methods for detection of group A streptococci. Significant variables in this procedure have included the selection of inhibitory versus noninhibitory agar media and the atmosphere (, with 5 to 10% C02, or an) and duration (1 day versus 2) of incubation. This review documents studies that have addressed these variables, compares their methods and interpretations, and, in light of these comparisons, makes recommendations for the selection of suitable throat culture reference methods for optimal detection of group A streptococci and for precise evaluations of new rapid antigen detection kits. NEED FOR AN ACCURATE CULTURE METHOD The proper evaluation of any new diagnostic test requires that the investigator
