VIDAS® D-Dimer Exclusion™ II

Safe exclusion of Venous Thromboembolism

VIDAS® D-Dimer Exclusion™ II is a highly-sensitive automated D-Dimer assay. In conjunction with assessment of clinical pretest probability, it allows safe exclusion of deep vein thrombosis (DVT) and pulmonary embolism (PE) in both low and intermediate suspected outpatient risk groups in just 20 minutes.

  • Over 99% sensitivity and negative predictive value (NPV)
  • First automated assay to obtain FDA clearance for safe VTE exclusion
  • Most tested and referenced D-Dimer assay available

Do you need more information

VIDAS® D-Dimer Exclusion™ II is an automated test for the immunoenzymatic determination of fibrin degradation products in human plasma. Combined with pretest probability (PTP) scores, it can safely be used to exclude both PE and DVT in suspected patients attending the emergency department (ED) with common symptoms such as chest pain and dyspnea1. Due to its high sensitivity and negative predictive value, VIDAS® D-Dimer Exclusion™ II enables safe exclusion of up to 50% of outpatients, leading to a significant reduction in the global cost of diagnosis2.

Testing strategy

According to international guidelines*, there are two essential steps for cost-efficient and safe exclusion of VTE:

  1. Clinical Assessment: use of validated pre-test probability (PTP) scores to classify patients into low, intermediate or high risk for VTE
  2. Use of a high-sensitivity D-Dimer assay to enable safe exclusion of VTE in patients in low and intermediate risk groups.

Test benefits

1. Compliant with CLSI guidelines*:

  • High sensitivity and NPV**, enabling safe VTE exclusion of both low and intermediate risk patients corresponding to approximately 50% of outpatient population presenting with symptoms
  • Results: reduced imaging, cost savings and rapid turn-around of emergency patients


2. Rapid 20 minutes test result fitting into emergency time requirements and rapid patient triage

3. Streamlined laboratory workflow and cost control

  • Calibration only once a month
  • No test warm-up period
  • Easy-to-perform reconstitution of the calibrators and controls using distilled water

Extensive clinical validation

  • Included in 7 prospective outcome studies / over 8,000 patients enrolled (suspected PE)3
  • 3-month follow-up in 2,166 patients with low/intermediate PTP and normal D-dimer3
  • Failure rate: 0.14% (NPV 99.9%)3
  • Currently used in several major outcome studies (REVERSE5 & ADJUST)

VIDAS® Emergency range

VIDAS® D-DIMER Exclusion™ II is a key component of the VIDAS Emergency range, which also includes markers of cardiac necrosis, heart failure and severe bacterial infections.

The VIDAS solution allowing 24/7 on-demand testing is particularly adapted to emergency conditions and rapid patient triage.
