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%.
What is the Centor criteria used for?

Centor criteria A score of 0, 1 or 2 is thought to be associated with a 3 to 17% likelihood of isolating streptococcus. A score of 3 or 4 is thought to be associated with a 32 to 56% likelihood of isolating streptococcus.
Does Centor criteria apply to children?
Our results confirm that, at least in children, Centor criteria are an unreliable tool to assess the probability of the presence of GABHS; thus, its use should be discouraged. The strength of this study is the large number of children included.
How many Centor criteria do you need?
The Centor Criteria is a four-point scoring system used to assist with risk stratification for GAS pharyngitis and clinical decision making. The four components of the Centor Criteria are: fever, tonsillar exudate, anterior cervical lymphadenopathy, and absence of cough.
How do you remove tonsillar exudate?
Patients may attempt to dislodge and remove tonsillar exudate with soft, non-dangerous tools, such as Q-tips. However, this is usually futile, as the exudate frequently recurs. Gargling with warm, salt water or antiseptic mouthwashes is acceptable, but again the relief is usually short lived.
How are Centor criteria used to diagnose children?
Prevalence (%) of all four Centor criteria in children with a group A β haemolytic Streptococcus (GABHS)-positive and GABHS-negative throat swab culture, respectively. Likelihood ratios (LR) for both age groups are shown in tables 2 and 3.
Is the Journal of Pediatrics a peer reviewed journal?
The Journal of Pediatrics is an international peer-reviewed journal that advances pediatric research and serves as a practical guide for pediatricians who manage health and diagnose and treat disorders in infants, children, and adolescents.
How are Centor criteria used in the emergency department?
To evaluate the correlation between Centor criteria and presence of GABHS in children with sore throat admitted to our emergency department, in order to evaluate the value of this prediction rule. Results confirm the ineffectiveness of Centor criteria as a predicting factor for finding GABHS in a throat swab culture in children.
What are the four components of the Centor criteria?
The Centor Criteria is a four-point scoring system used to assist with risk stratification for GAS pharyngitis and clinical decision making. The four components of the Centor Criteria are: fever, tonsillar exudate, anterior cervical lymphadenopathy, and absence of cough.
