Wells Score for DVT
Assess clinical probability of deep vein thrombosis using Wells criteria.
Wells Criteria for DVT
Select all criteria that apply:
Wells Score for DVT
0
Low Risk
DVT Probability: 5%
Three-Tier Risk
Low Risk
Two-Tier Risk
DVT Unlikely
Recommended Action
Low probability. D-dimer testing recommended. If negative, DVT can be ruled out.
Three-Tier Model
- ≤0: Low risk (5% probability)
- 1-2: Moderate risk (17% probability)
- ≥3: High risk (53% probability)
Two-Tier Model
- < 2: DVT unlikely (6%) - D-dimer testing
- ≥2: DVT likely (28%) - Ultrasound
Clinical Note
Calf swelling should be measured 10 cm below tibial tuberosity. Consider proximal ultrasound for moderate/high risk patients.
