How is streptococcal pharyngitis diagnosed?
Clinicians need to use either a rapid antigen detection test (RADT) or throat culture to confirm group A strep pharyngitis. RADTs have high specificity for group A strep but varying sensitivities when compared to throat culture. Throat culture is the gold standard diagnostic test.
