- Culture on selective media.
- If MRSA grows, confirmatory ID and susceptibility testing follow.
Colonization vs. Infection
- Asymptomatic carriage: Many people harbor throat MRSA without illness.
- Symptomatic infection: Can cause tonsillitis, pharyngitis, or deep neck infections.
Importance
Prompt identification and treatment prevent complications. Discuss results with your provider.
