The Triage® D-Dimer Test is a fluorescence immunoassay to be used with the Triage® Meter Plus for the quantitative determination of crosslinked fibrin degradation products containing D-dimer in EDTA whole blood and plasma specimens. The test is used as an aid in the assessment and evaluation of patients suspected of having disseminated intravascular coagulation or thromboembolic events including pulmonary embolism.
The Triage® D-Dimer Test is a fluorescence immunoassay to be used with the Triage® Meter Plus for the quantitative determination of cross-linked fibrin degradation products containing D-dimer in EDTA whole blood and plasma specimens.
The provided document describes the Triage® D-Dimer Test, a fluorescence immunoassay for quantitative determination of D-dimer in blood and plasma. The K042890 submission establishes its substantial equivalence to a predicate device, the Triage® Profiler S.O.B. Panel (K040437).
1. Table of Acceptance Criteria and Reported Device Performance
The document does not explicitly state "acceptance criteria" in terms of specific performance thresholds for sensitivity, specificity, accuracy, etc. Instead, it describes a method comparison study to demonstrate "substantial equivalence" to a predicate device, which implies that its performance should be comparable to the established predicate.
| Performance Metric | Acceptance Criteria (Implied by Substantial Equivalence) | Reported Device Performance |
|---|---|---|
| Method Comparison (Correlation to Predicate) | Performance characteristics equivalent to predicate methods | Slope of 0.999, Intercept of -85.89, Correlation Coefficient of 0.92 |
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size for Test Set: 180 specimens.
- Data Provenance: Not specified in the provided document. It does not mention the country of origin or whether the data was retrospective or prospective.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
Not applicable. This device is an in-vitro diagnostic test. The "ground truth" for the method comparison was based on the results from the predicate device, not on expert consensus or adjudication. The document does not mention any human readers or experts used to establish a ground truth for the device's performance in this context.
4. Adjudication Method for the Test Set
Not applicable. As described above, the ground truth was based on a predicate device's results, not on interpretation by experts requiring adjudication.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
No, an MRMC comparative effectiveness study was not conducted. The study performed was a method comparison study between the new device and a predicate device.
6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done
Yes, the study described is a standalone performance assessment of the Triage D-Dimer Test. It directly compares the quantitative results of the Triage D-Dimer Test to a predicate method, without involving human interpretation or a human-in-the-loop component for the device being evaluated.
7. The Type of Ground Truth Used
The ground truth for the method comparison study was established by the results obtained from the predicate device. The underlying "ground truth" for D-dimer measurements in general would be the actual concentration of D-dimer in the specimens, as measured by a validated method.
8. The Sample Size for the Training Set
The document does not provide information about a training set. The study described is an analytical performance study (method comparison) using 180 specimens. It is possible that the device underwent internal development and validation with other data, but this is not detailed in the 510(k) summary.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as no training set details are provided in the document.

். Predicate Devices

D. Device Description and Intended Use
The Triage® D-Dimer Test is a fluorescence immunoassay to be used with the Triage® Meter Plus for the quantitative determination of cross-linked fibrin degradation products containing D-dimer in EDTA whole blood and plasma specimens. The test is used as an aid in the assessment and evaluation of patients suspected of having disseminated intravascular coagulation or thromboembolic events including pulmonary embolism.
D-dimer is a protein arising directly from the body's natural mechanism to break down blood clots. Elevated levels of D-dimer in a patient's blood are indicative of abnormal rates of increased clot burden. Published studies suggest that D-dimer can be useful in the evaluation of suspected pulmonary embolism (PE).
{1}------------------------------------------------
Summary of Comparison Data ட்
A method comparison of D-dimer results was performed using 180 specimens throughout the measurable range of the test. A Passing-Bablok regression analysis of the results yielded a linear relationship with a slope of 0.999, an intercept of -85.89 and a correlation coefficient of 0.92. The analytical performance characteristics of the assay were equivalent to predicate methods.
ட் Conclusion
In conclusion, these studies demonstrate the substantial equivalence of the Triage D-Dimer Test to existing products already marketed for detecting the presence and degree of intravascular coagulation and fibrinolysis. They further demonstrated the suitability of the product for laboratory and professional use. Such studies are a critical element in establishing the fundamental safety and effectiveness of the product and its appropriateness for commercial distribution.

Trade/Device Name: Triage D-Dimer Test Regulation Number: 21 CFR 864.7320 Regulation Name: Fibrinogen/fibrin degradation product assay Regulatory Class: Class II Product Code: GHH, DAP Dated: November 19, 2004 Received: November 22, 2004
Dear Mr. Dahlen:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration. Ilsting of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820). This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
