Wells PE Score

Wells PE Score: calculated with the published clinical method, with result interpretation. A reference tool that does not replace a doctor's advice.

ℹ Reference calculation based on the published method. It does not replace a clinical examination or a doctor's decision.

Wells PE Score

Clinical signs of DVT (1 = yes)
PE is the most likely diagnosis (1 = yes)
Heart rate >100 bpm (1 = yes)
Immobilization ≥3 days or surgery in the past 4 weeks (1 = yes)
Prior DVT or PE (1 = yes)
Hemoptysis (1 = yes)
Malignancy (treated within 6 months or palliative) (1 = yes)

What it calculates

The “Wells PE Score” calculator computes Wells score for PE, points from 7 parameters: clinical signs of dvt (1 = yes), pe is the most likely diagnosis (1 = yes), heart rate >100 bpm (1 = yes), immobilization ≥3 days or surgery in the past 4 weeks (1 = yes), prior dvt or pe (1 = yes), hemoptysis (1 = yes), malignancy (treated within 6 months or palliative) (1 = yes).

Used by professionals and patients to assess health metrics, dosages, and risks.

Example calculation

With parameters Clinical signs of DVT (1 = yes) = 0, PE is the most likely diagnosis (1 = yes) = 0, Heart rate >100 bpm (1 = yes) = 1, Immobilization ≥3 days or surgery in the past 4 weeks (1 = yes) = 0, Prior DVT or PE (1 = yes) = 1, Hemoptysis (1 = yes) = 0, Malignancy (treated within 6 months or palliative) (1 = yes) = 0 the result is 3 (If PE is unlikely, use D-dimer to rule it out).

How to use

  1. Enter clinical signs of dvt (1 = yes), pe is the most likely diagnosis (1 = yes), heart rate >100 bpm (1 = yes), immobilization ≥3 days or surgery in the past 4 weeks (1 = yes), prior dvt or pe (1 = yes), hemoptysis (1 = yes) and malignancy (treated within 6 months or palliative) (1 = yes) — each field above is adjustable with a slider.

FAQ

How is BMI calculated?
BMI = weight (kg) / height (m)². Example: 70 kg / (1.75 m)² = 22.9. The WHO normal range is 18.5–24.9; below that is underweight, 25–29.9 is overweight, and 30+ is obese.
Is BMI accurate for everyone?
No. BMI does not distinguish muscle from fat, so athletes may show a high BMI with low body fat. It is also less reliable for teenagers, pregnant people, older adults, and very tall or short individuals.
What are the BMI categories?
Underweight: below 18.5. Normal: 18.5–24.9. Overweight: 25–29.9. Obese class I: 30–34.9; class II: 35–39.9; class III: 40+.
What is a better measure than BMI?
Body fat percentage, waist-to-height ratio (aim for under 0.5), and waist circumference give a clearer picture of health than BMI alone.
