Primary Outcome Measures:
  • To demonstrate the ability of STA Liatest DDi combined with a clinical pretest probability (PTP) to safely exclude pulmonary embolism or deep venous thrombosis in a 3 month follow-up [ Time Frame: at 3 months ] [ Designated as safety issue: Yes ]
    Occurence of pulmonary embolism or deep venous thrombosis during the 3 month follow-up after negative diagnosis (i.e. patients with PTP low/moderate and negative STA Liatest D-Di test)

Secondary Outcome Measures:
  • 1. To analyse results homogeneity (inter-centers) in the group "positive D-dimer result and negative diagnosis" (descriptive statistics only). 2. To determine prevalence of VTE in PTP high patients based on imaging results [ Time Frame: at 3 months ] [ Designated as safety issue: Yes ]
    1. Prevalence of VTE in PTP high patients based on imaging results.

Biospecimen Retention:   Samples Without DNA
plasma samples (at least 1 aliquot 0.5 ml) will be collected at the initial visit of patients with low or moderate PTP

Estimated Enrollment: 2612
Study Start Date: November 2011
Estimated Study Completion Date: December 2016
Estimated Primary Completion Date: November 2016 (Final data collection date for primary outcome measure)
Detailed Description:

The study population will be selected from prospective, consecutive ambulatory outpatients suspected of having venous thromboembolism.

These patients will first be evaluated using the Wells score:

  • patients with low or moderate pretest probability will be considered for D-dimer testing, those with D-dimer positive will be considered for an imaging procedure,
  • patients with high pretest probability will be considered for an imaging procedure.

Patients with "low or moderate" pretest probability and a negative D-Dimer result will be followed for 3 months to evaluate potential development of deep venous thrombosis and/or pulmonary embolism.

These patients will be contacted by phone 3 month after their first visit.


Ages Eligible for Study:   up to 80 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
The study population will be recruited from prospective, consecutive, ambulatory outpatients (presenting at the emergency unit or outpatient clinic) suspected of having venous thromboembolism


  1. Patient is < 80 years old.
  2. Patient presenting at least one of these symptoms indicative of proximal DVT or PE:

    • symptoms for proximal DVT: leg pain, tenderness (discomfort through palpation), leg swelling, and /or edema,
    • symptoms for PE: hemoptysis, lung related chest pain, dyspnea.
  3. Patient provides written informed consent to participate in the study (or verbal no-opposition, as allowed by local regulations)
  4. Patient is willing to comply with specified follow-up evaluation at 3 months and can be contacted by telephone


  1. Patient presenting with a condition that may be associated with increased D-dimer levels, even in the absence of VTE, such as:

    • Fibrinolytic therapy within the previous seven (7) days,
    • Bone fracture or surgery (with general anesthesia longer than thirty (30) minutes) within the previous one (1) month,
    • Deep hematoma diagnosed by imaging techniques within the previous one (1) month,
    • Disseminated malignancies and active cancer (active cancer defined as: cancer for which therapeutic or palliative treatment is either ongoing at the time of enrolment or has stopped less than six (6) months before enrolment),
    • Sepsis, severe infections, pneumonia within the previous 1 month,
    • Known liver cirrhosis,
    • Pregnancy or post-partum within the previous 1 month,
    • Atherosclerotic vascular disease thrombosis within the previous 1month (e.g. myocardial infarction, stroke, coronary syndrome, peripheral artery disease stage III or IV),
    • Sickle cell disease,
  2. Patients presenting with a suspect thrombotic event related to catheter implantation
  3. Ongoing therapeutic anticoagulants (curative and preventive treatment) starting twenty four (24) hours or more before the D-dimer is measured
  4. Previous anticoagulant therapy stopped less than three (3) months before the D-dimer is measured
  5. Patients with previous DVT/PE occurred less than three (3) months from screening.
  6. Suspect thrombotic events in other locations at screening, including distal to the knee and upper extremity DVT (based on standard of care examinations)
  7. Patients with known tissue plasminogen activator (tPA) deficiency
  8. Patient participating or who has participated within one month of enrollment in another investigational study
  9. Major co-morbid condition(s) or other reasons that could limit the patient's ability to participate in the study or to comply with follow-up requirements, or impact the scientific integrity of the study
