Answer

The appropriate bacteriologic confirmation of the tentative diagnosis of streptococcal pharyngitis is disputed. Fifteen years after their introduction into clinical practice, controversy persists regarding the relative merits of antigen detection systems for S pyogenes compared with traditional throat culture. Despite technologic improvements in rapid streptococcal testing, the throat culture remains the criterion standard for the diagnosis of streptococcal pharyngitis.
