Calculator
How it works and when to use it
The score adds points for signs of DVT (3), PE as the most likely diagnosis (3), heart rate over 100 (1.5), immobilisation or recent surgery (1.5), previous DVT or PE (1.5), haemoptysis (1) and malignancy (1).
Three tiers: under 2 low, 2 to 6 moderate, over 6 high probability, and two tiers: over 4 PE likely, 4 or less PE unlikely, usually followed by a D-dimer.

Frequently asked questions
Why use the score when CT is available?
It sets the probability before testing, and with a low probability a negative D-dimer may rule PE out without imaging.
Can it be used in pregnancy?
It was not designed for pregnancy, and adapted diagnostic pathways for pregnant women are for the doctor to choose.
