Revised Geneva Score Calculator for PE
Estimate the pre-test probability of pulmonary embolism (PE) with the revised Geneva score — a fully objective clinical prediction rule that, unlike the Wells score, needs no judgement about whether PE is the most likely diagnosis. Tick the risk factors and clinical signs and pick the heart-rate band to get the score, the three-tier probability (low / intermediate / high) and the two-tier (PE unlikely / likely) result.
About the revised Geneva score
The revised Geneva score estimates the pre-test probability of pulmonary embolism from eight fully objective items, avoiding the subjective element of the Wells rule.

Frequently asked questions
How is the revised Geneva score calculated?
The revised Geneva score adds the points for each item: age over 65 (1); a previous DVT or PE (3); surgery under general anaesthesia or a lower-limb fracture in the past month (2); active malignancy, solid or blood, treated within the last year or ongoing (2); unilateral lower-limb pain (3); haemoptysis (2); heart rate 75–94 (3) or 95 and above (5); and pain on deep-vein palpation of the leg with unilateral oedema (4). The total runs from 0 to 22. Age over 65 is the only item worth a single point, while the highest heart-rate band and the combination of calf tenderness with unilateral oedema carry the most weight. None of the items depends on the assessor’s overall impression, which is what makes the score reproducible between clinicians.
What do the score bands mean?
In the three-tier revised Geneva scheme, 0–3 points is low probability (about 8% of patients have PE), 4–10 is intermediate (about 28%) and 11 or more is high (about 74%). A simpler two-tier version splits at 6: a score of 0–5 makes PE unlikely and 6 or more makes it likely. These bands guide whether to use D-dimer testing or move straight to CT pulmonary angiography.
How does the Geneva score differ from the Wells score?
Both estimate the pre-test probability of PE, but the revised Geneva score uses only objective items — age, history, heart rate and examination findings — whereas the Wells score includes the subjective judgement “PE is the most likely diagnosis”, worth three points. Removing that subjective element makes Geneva more reproducible between clinicians, at the cost of a little more data entry. The two scores perform similarly overall.
What should I do after getting the score?
A low or PE-unlikely revised Geneva result usually leads to a D-dimer: if that is normal, PE can often be excluded without imaging. An intermediate result also typically prompts a D-dimer. A high or PE-likely result usually means proceeding to CT pulmonary angiography rather than relying on D-dimer. The score supports, but does not replace, clinical assessment.
Is there a simplified version?
A simplified revised Geneva score does exist: it gives one point to each item and two points only to the highest heart-rate band, which is easier to remember and performs comparably. This calculator uses the original revised (weighted) version published by Le Gal and colleagues in 2006, which is the one most widely cited and validated. Either way, treat the result as a reference, not medical advice.
This is a reference tool, not a diagnosis or medical advice. Results depend on the laboratory, assay and clinical context, and reference intervals vary between labs and by age and sex — always read your result against the range printed on your own report and discuss it with a qualified healthcare professional.
