Revised Geneva Score Calculator

The revised Geneva score is a clinical prediction rule that estimates the pre-test probability of pulmonary embolism (PE) in patients with suspected PE. It was published by Le Gal and colleagues in 2006 and is fully standardized, meaning every item comes from the patient's history, physical exam, or vital signs. That makes it reproducible between clinicians, unlike rules that rely on a subjective gestalt.

You add weighted points for eight items: age over 65 (1 point), a previous DVT or PE (3), surgery under general anesthesia or a lower-limb fracture within 1 month (2), active malignancy (2), unilateral lower-limb pain (3), hemoptysis (2), a heart rate of 75 to 94 beats per minute (3) or 95 or higher (5), and pain on deep-vein palpation together with unilateral edema (4). The heart-rate bands do not stack, so a fast pulse adds at most 5 points. The total ranges from 0 to 22.

The score sorts patients into three tiers of clinical probability. A score of 0 to 3 is low probability, with roughly 8% of patients having PE in the original cohort; 4 to 10 is intermediate, around 28%; and 11 or more is high, around 74%. These percentages come from the Le Gal 2006 study and describe the group, not your individual patient.

Both rules estimate the pre-test probability of pulmonary embolism so you can decide on D-dimer testing or imaging. The main difference is that the revised Geneva score uses only objective items, while the Wells score includes the subjective judgment that PE is the most likely diagnosis. They perform similarly in validation studies, so use whichever your local protocol specifies and apply it consistently.

For low or intermediate probability, a negative high-sensitivity D-dimer, often age-adjusted, can safely rule out PE without imaging, while a positive D-dimer points toward CT pulmonary angiography. For high probability, D-dimer is not reliable enough to exclude PE, so imaging is usually the next step. This is decision support only, and the final plan depends on the full clinical picture.

No. This tool is for education only and is not a substitute for professional medical advice, diagnosis, or treatment. The revised Geneva score is one input into the workup of suspected pulmonary embolism and never replaces clinical judgment, D-dimer testing, imaging, or local protocols. Always confirm decisions with a qualified clinician.
