About Centor Score

The Centor Score is a validated clinical decision tool designed to estimate the probability of Group A Streptococcal (GAS) pharyngitis, commonly known as strep throat, in patients presenting with acute pharyngitis symptoms. Primarily utilized by healthcare professionals, this score integrates specific clinical findings—such as tonsillar exudates, swollen tender anterior cervical nodes, absence of cough, and a history of fever—to stratify a patient's risk. Its primary value lies in guiding appropriate diagnostic testing strategies, including rapid strep antigen detection tests or throat cultures, and promoting judicious antibiotic prescribing. By optimizing patient management and reducing unnecessary antibiotic use, the Centor Score plays a crucial role in combating antibiotic resistance.
