The Wells score is a clinical prediction rule used to estimate the probability of deep vein thrombosis (DVT). This calculator assists clinicians in deciding the appropriate diagnostic pathway.

Clinical Interpretation:
The Wells Score is a clinical prediction rule used to determine the probability of Deep Vein Thrombosis (DVT).
Total Score = (Sum of Clinical Criteria) - (Alternative Diagnosis Adjustment)
Consider a patient with active cancer and calf swelling, which normally awards 2 points. However, if the clinician finds an alternative diagnosis to be at least as likely as DVT, 2 points are subtracted, resulting in a total score of 0.
What does a low score mean?
A low score indicates a low clinical probability, typically suggesting a D-dimer test to rule out DVT.
When is ultrasound needed?
Ultrasound is usually indicated for moderate or high scores.
Is this score definitive?
No, it is a screening tool to guide further diagnostic testing like imaging.
