About Wells Score For DVT Calculator

Counts the nine one-point Wells criteria for deep vein thrombosis and subtracts two points when an alternative diagnosis is at least as likely.

Formula

Wells DVT

Score = number of one-point criteria - 2 if an alternative diagnosis is at least as likely; 2 or more means DVT likely

Frequently Asked Questions

Is the two-tier or three-tier version used?

Most pathways use the two-tier version, combining an unlikely score with a negative D-dimer to rule out DVT.

Does the score diagnose DVT?

No. It stratifies pre-test probability to decide whether D-dimer or ultrasound comes next.
