Centor/McIsaac
Strep Throat
For education. Check every result.
Anatium is a study resource, not medical advice. Nothing here is a diagnosis, a prescription or a substitute for a clinician who has seen the patient. Check every number against a current local protocol before it touches anyone, and never act on a result you cannot reproduce yourself.
How it is calculated
McIsaac-modified Centor: exudate, tender anterior nodes, fever, absence of cough, plus an age adjustment. Most sore throats are viral, and the score exists to reduce antibiotic use.
About
How likely a sore throat is streptococcal, and therefore who might benefit from testing or antibiotics.
