Wells PE

PE Probability

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

Wells score for PE. This tool bands by the original three-level split: low under 2, moderate 2-6, high above 6. The two-level version is now more widely used: 4 or less is "PE unlikely", which goes to a D-dimer, and above 4 is "PE likely", which goes to imaging. Check which one your local pathway is written around.

About

Pre-test probability of a pulmonary embolism, deciding who needs imaging and who can be ruled out with a D-dimer.
