Can be applied for patients whose clinical presentation is concerning for a DVT in order to risk stratify.

Active cancer (<6 mo) - 1pt
Paralysis, paresis, or immob of extremity - 1pt
Bedridden >3 d b/c of symptoms (within 4 wk) - 1pt
TTP along deep venous system - 1pt
Entire leg swollen - 1pt
Unilateral calf swelling >3cm below tibial tuberosity - 1pt
Unilateral pitting edema - 1pt
Collateral superficial veins (not varicose) - 1pt
Previously documented DVT - 1pt
Alternative diagnosis as likely or more likely than DVT - (-)2pts

Scoring:

A score of 0 or lower → minimal risk - DVT prevalence of 5%. D-dimer testing is safe in this group - negative d-dimer decreases the probability of disease to <1% allowing an ultrasound to be deferred.
A score of 1-2 → moderate risk - DVT prevalence of 17%. D-dimer testing still effective and a negative test decreases post-test probability disease to <1%
A score of 3 or higher → high risk - DVT prevalence of 17-53% → patients should receive an ultrasound^[1]

-A '''score of 0 or lower''' is associated with [[DVT]]unlikely with a prevalence of [[DVT]]of 5%. D-dimer testing is safe in this group and will decrease the probability of disease to <1 % allowing an [[DVT ultrasound|ultrasound]] to be deferred. '''A score of 1-2''' is considered moderate risk (17%) for [[DVT]]but can still proceed with testing using a high sensitivity D-dimer to decrease the post test probability of a [[DVT]] to <1% if negative but require [[DVT ultrasound|ultrasound]] if positive.  '''A score of 3 or higher''' suggests [[DVT]]is likely (17-53%) and patients should receive an [[DVT ultrasound|ultrasound]] but also send a [[d-dimer]] because if the [[D-dimer]] is positive and the ultrasound is negative, the patient should receive a followup ultrasound in 2 weeks.<ref>Del Rios M et al.
