About the Wells Score for DVT
The Wells Score for DVT is a clinical prediction rule that sums features associated with deep vein thrombosis into a single score. It can support standardized assessment and help guide testing pathways when paired with local protocols.
Common Interpretation (Educational)
- ≤0: Low probability
- 1–2: Moderate probability
- ≥3: High probability
