Are the Centor criteria accurate in diagnosing streptococcal pharyngitis?

They are not diagnostic but may be considered to guide further management. The Centor criteria can be used to estimate the probability of streptococcal pharyngitis and are best used in a high prevalence setting (SOR: A, meta-analysis).

Is Group C strep pharyngitis treated?

Non–group A beta-hemolytic streptococci (groups C and G) also can cause acute pharyngitis; these strains are usually treated with antibiotics, although good clinical trials are lacking.

What is a positive Centor score?

In adults, the positive predictive value of the Centor criteria for predicting GAS pharyngitis is around 40% if 3 criteria are met, and about 50% if 4 criteria are met. These criteria along with other clinical features should be used to guide treatment for pharyngitis in adults.

How accurate is Centor criteria?

As a decision rule for considering antibiotic prescribing (score ≥ 3), the Centor score has reasonable specificity (0.82, 95% CI 0.72 to 0.88) and a post-test probability of 12% to 40% based on a prior prevalence of 5% to 20%.
