'''Scoring:'''
'''Scoring:'''
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

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

  • Entire leg swollen - 1pt
  • Unilateral calf swelling >3cm below tibial tuberosity - 1pt
  • Unilateral pitting edema - 1pt
