Triage® D-Dimer Test: Product Info
Aids in the assessment and evaluation of patients suspected of having disseminated intravascular coagulation (DIC) and thromboembolic events including pulmonary embolism (PE) and deep venous thrombosis (DVT).
- Uses highly sensitive, quantitative immunoassay technology.1
- Utilizes the 3B6 D-dimer antibody, which has demonstrated high clinical specificity for PE and DVT.2,3
- Correlates with ELISA and other immunoassay methods.1,5
- Delivers quantitative results in approximately 15 minutes in the lab or at the point-of-care.
- Performed on the Triage Meters; the Triage System is widely adopted by over 3,500 hospitals worldwide.
The Immunoassay Technology Advantage
The Triage D-Dimer Test is a fluorescence immunoassay that quickly provides accurate, quantitative D-dimer results.
- D-dimer assays are known to have varied sensitivity for detecting D-dimer.2,3
- Enzyme-linked immunosorbent assays (ELISA) are known for their high sensitivity in patients with suspected PE and DVT.4
- ELISA assays are distinguishable from latex agglutination tests due to the presence of capture and detection antibodies, forming a sandwich immunoassay, yielding higher sensitivity.3
- The Triage D-Dimer Test uses highly sensitive sandwich immunoassay technology to capture and detect D-dimer.1
- The Triage D-Dimer Test, a fluorescent immunoassay (FIA), directly measures the fluorescent signal that is proportionate to the analyte present in the sample.1
Lateral Flow Sandwich Immunoassay
3B6 Antibody
Measurement of D-dimer is useful in evaluating patients suspected of PE, DVT and DIC, yet not all D-dimer tests are able to detect D-dimer the same way.
- Antibody specificity plays a significant role in distinguishing D-dimer from other Fibrin Degradation Products (FDPs).2
- The Triage D-Dimer Test utilizes the 3B6 monoclonal antibody that is highly specific to cross-linked D-dimer.1,2,3
The ability to distinguish D-dimer from other FDPs, is achieved with the 3B6 antibody, which detects the cross-linked epitope of D-dimer.

Plasmin derived FDPs may be detected in addition to D-dimer, resulting in an erroneously elevated result |
The 3B6 antibody detects only cross-linked FDPs (D-dimer) for accurate measurement of the sample |
The Performance You Expect
The Triage D-Dimer Test has a correlation coefficient of 0.92 (r value) to the Stratus CS® D-dimer method (Passing-Bablok regression).1.
