What is the Centor criteria for strep throat?
What is the Centor criteria for strep throat?
The four components of the Centor Criteria are: fever, tonsillar exudate, anterior cervical lymphadenopathy, and absence of cough.
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.
When do you use Centor criteria?
The Centor criteria are used to determine the likelihood of GAS in adults. One point is given for each criterion; the likelihood of GAS pharyngitis increases as total points rise. We generally test for GAS in patients with ≥3 Centor criteria; patients with Centor criteria <3.
Why is it called Centor criteria?
Mnemonic using criteria name A mnemonic to remember Centor is: C – Cough absent, or the incorrect but memorable “Can’t Cough” E – Exudate. N – Nodes.
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%.
Can you use Centor criteria in children?
Symptoms suggestive of viral or GAS The Centor criteria are only validated for adult patients in primary care and are not validated for children under the age of 3 due to the different clinical presentation of GAS in the first years of life.
How accurate is the Centor score?
What modified Centor criteria?
The Modified Centor Score (also known as the McIssac Score or the McIssac Modification of the Centor Score) helps predict the probability of streptococcal pharyngitis by taking into consideration risk factors such as patient’s age, symptoms, and physical exam.

How reliable is the Centor score?
Are the Centor criteria accurate in diagnosing streptococcal pharyngitis?
EVIDENCE-BASED ANSWER. 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).
