The American Academy of Pediatrics (AAP) recommends that negative RADT results in children be confirmed using throat culture unless physicians can guarantee that RADT sensitivity is similar to that of throat culture in their practice.13 False-negative RADT results may lead to misdiagnosis and GABHS spread and, very rarely, to increased suppurative and nonsuppurative complications.
