Rapid Antigen Detection Test Algorithm for Acute Pharyngitis[1]

Category Testing and Treatment
Clinical features strongly suggesting viral etiology (eg. cough, rhinorrhea, hoarseness, oral ulcers)
  • None
<3 years old
  • None because immature immune system not mature enough to develop anti-streptolysin O (ASO) antibodies and acute rheumatic fever[2].
    • Unless they have a special risk factor (e.g. older sibling with GAS infection)
CENTOR = 1
  • None
None of the above with CENTOR ≥2
  • Send rapid antigen detection test
    • Positive = treat
    • Negative
      • Children and adolescents
        • Send back up throat culture (treat later, if positive)
      • Adults
        • None (no need for back up throat culture)

Diagnostic testing or empiric treatment of asymptomatic household contacts of patients with acute streptococcal pharyngitis is not routinely recommended
