Revised Geneva Score Calculator — Pulmonary Embolism Pre-test Probability
The Revised Geneva Score stratifies patients into low, intermediate, or high pre-test probability for pulmonary embolism using eight objective, bedside-measurable clinical variables — no arterial blood gas or d-dimer required for scoring.
Age > 65 years (+1)
Previous DVT or PE (+3)
Surgery or fracture within 1 month (+2)
Active malignancy (+2)
Unilateral lower limb pain (+3)
Hemoptysis (+2)
Heart rate
Lower limb deep vein palpation pain + unilateral edema (+4)
Range 0–22: Low (0–3), Intermediate (4–10), High (≥ 11)

How does this calculator work?
Sum eight clinical variables (age >65, prior DVT/PE, recent surgery/fracture, malignancy, limb pain, hemoptysis, heart rate, DVT palpation/edema) into a score of 0–22. Score 0–3 = low PE probability (~8%); 4–10 = intermediate (~28%); ≥11 = high (~74%). No physician-judgment items — all variables are objectively measured.
Formula
How this is calculated
The Revised Geneva Score (Klok et al. 2008) is a validated, fully standardised clinical decision rule for estimating the pre-test probability of pulmonary embolism. Unlike the Wells PE score, it contains no physician-judgment item — every variable is objectively measurable at the bedside. The eight criteria are summed: scores 0–3 correspond to low probability (~8% PE prevalence), 4–10 to intermediate probability (~28%), and ≥11 to high probability (~74%).
The score is best used in conjunction with d-dimer testing under PERC/YEARS algorithms or directly to guide imaging decisions. In low-probability patients with a negative sensitive d-dimer, PE can often be excluded without CT pulmonary angiography. The score does not replace clinical judgment or account for hemodynamic instability; patients with suspected massive PE should proceed to imaging regardless of score.
Limitations: validated primarily in emergency department populations with suspected PE; accuracy may differ in inpatients or atypical presentations. Prevalence probabilities cited (~8%, ~28%, ~74%) are approximate values from the original validation cohort.
Frequently asked questions
The Wells PE score includes a subjective "PE more likely than alternative diagnosis" item worth 3 points, making it examiner-dependent. The Revised Geneva Score uses only objective, standardised variables, reducing inter-observer variability and making it easier to apply consistently across clinicians.
A low score (0–3) reduces PE probability to ~8% but does not rule it out alone. Combined with a negative high-sensitivity d-dimer (or a negative PERC rule in suitable patients), PE can generally be excluded without CT imaging. Always apply within your clinical context and local pathway.
A score ≥11 places the patient in high pre-test probability. Guidelines recommend proceeding directly to CT pulmonary angiography (CTPA) rather than waiting for d-dimer, as a negative d-dimer alone is not sufficient to exclude PE in high-probability patients. Anticoagulation should be considered while imaging is arranged if clinical suspicion is strong.
