Wells Score for Deep Vein Thrombosis (DVT)
LOW RISK
Wells PS et al. Evaluation of D-dimer in the diagnosis of suspected deep-vein thrombosis. N Engl J Med 2003;349:1227-1235; CHEST 2021 Guidelines for Antithrombotic Therapy for VTE (2003)
Wells Score for Deep Vein Thrombosis (DVT)
Applicable Population: Adult outpatients (>= 18 years) with suspected lower extremity DVT
Calculated Score:
0
points
Clinical Interpretation
Low Probability / DVT Unlikely (0 points)
Guideline-Directed Recommendation
DVT Unlikely (~ 5% probability). High-sensitivity D-dimer test indicated. If D-dimer negative (below age-adjusted cutoff), DVT safely ruled out without ultrasound.
Clinical Alerts & Safety Warnings
- In pregnant patients or recurrent DVT, Wells score has reduced specificity; specialized obstetric/thrombosis pathways apply.
