Diagnostic Testing for Sore Throat

Answer:

Rapid Antigen Detection Test (RADT): Used for GAS pharyngitis; high

specificity, variable sensitivity; throat culture: Gold standard, used if RADT is

negative but suspicion remains; Monospot test: For suspected

mononucleosis; CBC with differential: May show lymphocytosis in viral

infections, atypical lymphocytes in EBV.

Pharmacologic Management of Pharyngitis

GAS pharyngitis: Penicillin V or Amoxicillin = first-line; alternatives: Azithromycin, Clarithromycin, or Clindamycin for penicillin-allergic patients; viral pharyngitis: supportive (analgesics, antipyretics, hydration); adjuncts: NSAIDs for pain, throat lozenges.
