Wells Score for DVT
The Wells score estimates the pre-test probability of deep vein thrombosis.
Scoring Criteria
Each criterion scores +1 point, except "alternative diagnosis as likely" which scores -2.
Risk Categories
Patients with low probability and negative D-dimer can safely avoid imaging.
计算示例
A patient with active cancer, bedridden >3 days, and calf swelling.
- 01Active cancer = +1
- 02Bedridden >3 days = +1
- 03Calf >3 cm larger = +1
- 04Total = 3 (High probability)
常见问题
What is the Wells score?
The Wells score is a clinical decision tool that estimates the probability of DVT based on signs, symptoms, and risk factors. It was developed by Dr. Philip Wells.
What happens after calculating the Wells score?
Low-probability patients get a D-dimer blood test. If negative, DVT is ruled out. Moderate and high-probability patients typically get an ultrasound.
Can I use this to diagnose DVT myself?
No. The Wells score is a clinical tool for healthcare providers. If you suspect a blood clot, seek immediate medical attention. Symptoms include leg pain, swelling, warmth, and redness.
