Are you using the right D-Dimer test to
SAFELY EXCLUDE outpatients with suspected VTE*?
Due to the relatively low disease prevalence in outpatients (20% or less),
D-Dimer testing plays a major role in rapid triage resulting in safe exclusion of up to
50% of patients with suspected VTE presenting to the emergency department. 1,2
Accurate, early diagnosis of VTE (DVT/PE*) is critical to prevent complications and risk of death.
2 ESSENTIAL STEPS FOR COST-EFFICIENT AND SAFE EXCLUSION OF VTE
1,2
n STEP 1: CLINICAL ASSESSMENT: use of validated pre-test probability (PTP) scores - e.g. the Revised Geneva score (PE) or
the Wells scores (DVT/PE) - to classify patients as having low, intermediate or high risk for VTE. 3,4,5
n S TEP 2: D-DIMER TESTING: use of a high-sensitivity assay to enable safe exclusion of VTE in Low & Intermediate patient
risk groups, thereby avoiding an unacceptable rate of missed diagnoses. 6
