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.

Fill in every field above, then select Calculate.

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.
