Revised Geneva Score Calculator (Pulmonary Embolism)
The revised Geneva score estimates the pre-test probability of pulmonary embolism from purely clinical variables — age, previous DVT/PE, recent surgery or fracture, active malignancy, unilateral limb pain, haemoptysis, heart rate, and leg-vein tenderness with oedema — without needing arterial blood gases or a chest X-ray.
Quick answer
The revised Geneva score adds points for age over 65 (1), previous DVT/PE (3), surgery or fracture within a month (2), active malignancy (2), unilateral leg pain (3), haemoptysis (2), heart rate (75–94 → 3, 95 or more → 5) and pain on leg-vein palpation with unilateral oedema (4). Totals of 0–3, 4–10 and 11 or more are low, intermediate and high probability of pulmonary embolism.
Revised Geneva factors
Heart rate
Low clinical probability (0–3)
The revised Geneva score is 0: low clinical probability (0–3). The bands are low (0–3), intermediate (4–10) and high (11 or more) clinical probability of pulmonary embolism.
This estimates pre-test probability to guide D-dimer testing or imaging — it does not diagnose or exclude a PE on its own. A clinician decides the next step.
How to use the Revised Geneva calculator
- 1Tick the clinical factors. Tick age over 65, previous DVT or PE, recent surgery or lower-limb fracture, active malignancy, unilateral leg pain, haemoptysis, and pain on leg-vein palpation with unilateral oedema, as they apply.
- 2Select the heart rate band. Choose the heart-rate band: under 75, 75–94, or 95 or more per minute.
- 3Read the probability band. The tool totals the points and shows the low (0–3), intermediate (4–10) or high (≥11) clinical probability of PE, to choose the next test with a clinician.

What is the advantage of the revised Geneva score?⌄
It uses only clinical variables — history, examination and heart rate — so it needs no arterial blood gas or chest X-ray and is fully standardised. This makes it reproducible between clinicians for estimating PE probability.
How does the revised Geneva score relate to D-dimer testing?⌄
A low or intermediate probability is usually combined with a D-dimer: a negative D-dimer can then exclude PE without imaging. A high probability generally proceeds straight to imaging such as CT pulmonary angiography. A clinician decides.
How does it compare with the Wells score for PE?⌄
Both estimate the pre-test probability of PE and perform similarly. The revised Geneva score avoids the more subjective Wells item "PE is the most likely diagnosis", which some clinicians prefer for standardisation.
