Wells Score Result
This calculator simplifies the process by allowing users to select relevant risk factors and instantly receive a total Wells score along with a risk category. It is especially useful for educational purposes, medical students, healthcare workers, and individuals trying to better understand pulmonary embolism risk factors.
In this guide, you will learn how the Wells Score Calculator works, how to use it properly, practical daily-life examples, key benefits, and frequently asked questions.
What Is the Wells Score?
The Wells Score is a clinical prediction rule developed to estimate the likelihood of pulmonary embolism. It assigns points to specific symptoms, medical conditions, and risk factors.
Based on the total score, patients are generally classified into:
- Low Risk
- Moderate Risk
- High Risk
The score helps healthcare providers decide whether additional tests such as D-dimer testing, CT pulmonary angiography, or ultrasound are needed.
Purpose of the Wells Score Calculator
The Wells Score Calculator helps users:
- Assess the probability of pulmonary embolism
- Understand important PE risk factors
- Quickly calculate total Wells points
- Identify whether risk is low, moderate, or high
- Support medical education and awareness
- Improve clinical decision-making efficiency
The calculator provides fast and organized results without manual scoring calculations.

Understanding Wells Score Risk Levels
Low Risk
A lower Wells score indicates a smaller likelihood of pulmonary embolism.
This often suggests that PE is less likely, though medical evaluation may still be needed depending on symptoms.
Moderate Risk
A moderate score suggests an intermediate probability of pulmonary embolism.
Additional testing is commonly recommended.
High Risk
A high Wells score indicates a strong possibility of pulmonary embolism and requires urgent medical attention and diagnostic testing.
Practical Example 1: Patient With Leg Swelling and Fast Heart Rate
Imagine a patient experiences:
- Leg swelling and tenderness
- Heart rate above 100 bpm
- Recent surgery
The selected conditions may total:
- DVT signs = +3
- Tachycardia = +1.5
- Recent surgery = +1.5
Total Wells Score:
6.0
Result:
Moderate Risk
This suggests that further medical testing may be necessary to confirm or rule out pulmonary embolism.
Practical Example 2: Patient With Cancer and Hemoptysis
Another patient has:
- Active cancer
- Coughing blood
- Pulmonary embolism considered the most likely diagnosis
Score Breakdown:
- PE most likely diagnosis = +3
- Hemoptysis = +1
- Active cancer = +1
Total Wells Score:
5.0
Result:
Moderate Risk
The physician may recommend imaging tests or blood tests for further evaluation.
