Four of six patients with negative RADT results received an antibiotic. The clinic practice was to send throat swabs from patients with negative RADTs to a commercial laboratory for back-up culture, but it is unknown whether the clinic obtained any GAS-positive throat cultures from RADT-negative patients.All patients who were administered an antibiotic received a cephalosporin, clindamycin, or amoxicillin-clavulanate rather than penicillin or amoxicillin as the initial antibiotic therapy.Three patients were prescribed a second course of an antibiotic
because of symptoms persisting >48 hours after the start of initial therapy; data provided did not indicate whether they were retested for GAS.
