Overview
Testing for pharyngitis usually is not recommended for children or adults with acute pharyngitis with clinical and epidemiological features that strongly suggest a viral etiology (eg, cough, rhinorrhea, hoarseness, and oral ulcers).[1] Diagnostic studies for GAS are not indicated for children <3 years old because acute rheumatic fever is rare in children <3 years old and the incidence of streptococcal pharyngitis and the classic presentation of streptococcal pharyngitis are uncommon in this age group. Selected children <3 years old who have other risk factors, such as an older sibling with GAS infection, may be considered for testing.[1]
Laboratory Findings
Viral Etiology
Bacterial Etiology
Group A streptococcus: No single element in the history or physical examination is sensitive or specific enough to exclude or diagnose strep throat.[2]
Diphtheria: The diagnosis, which may be strongly suspected on epidemiologic and clinical grounds, should be confirmed by culture of the pseudomembrane in Loeffler’s or tellurite selective medium.[3]
Neisseria gonorrhoeae: The diagnosis should be confirmed by culture on Thayer–Martin medium.[3]
