Intended Use

System reagent for the quantitative determination of D-Dimer in human plasma on OLYMPUS analyzers.

Aid in detecting the presence and degree of intravascular coagulation and fibrinolysis, and in monitoring therapy for disseminated intravascular coagulation.

Device Description

In this Olympus procedure, the decrease in light intensity transmitted (increase in absorbance) through particles suspended in solution is as a result of complexes formed during the immunological reaction between the D-Dimer of the patient serum and the anti-human D-Dimer antibodies coated on the latex particles

2. Sample Size and Data Provenance for Test Set

The document does not explicitly state the sample size for the test set used in performance evaluations (e.g., precision, method comparison, interfering substances). It refers generically to "samples" for precision and provides a "Range" for method comparison without indicating the number of individual patient samples.
The data provenance (country of origin, retrospective/prospective) is not specified.

3. Number and Qualifications of Experts for Ground Truth

Not applicable. This device is an in vitro diagnostic (IVD) for quantitative measurement, and its performance is assessed against established analytical methods and reference standards, not against expert human interpretation of images or other diagnostic findings.

4. Adjudication Method for Test Set

Not applicable. Clinical test performance is determined by a quantitative measurement against a comparative method.

5. Multi Reader Multi Case (MRMC) Comparative Effectiveness Study

Not applicable. This is an in vitro diagnostic device for quantitative chemical analysis, not a medical imaging or diagnostic aid that involves human reader interpretation.

6. Standalone (Algorithm Only) Performance

Yes, the performance characteristics (Precision, Assay Range, Analytical Sensitivity, Method Comparison, Interfering Substances, Stability) represent the standalone performance of the Olympus D-Dimer Test System, as measured on Olympus analyzers, without human intervention in the result generation beyond operating the instrument.

7. Type of Ground Truth Used

The ground truth for evaluating the Olympus D-Dimer Test System implicitly relies on:

  • A commercially available assay (predicate device, Roche Tina-Quant® D-Dimer) for method comparison. This assay itself would have been validated against a traceable standard.
  • In-house Master Calibrator: The Olympus D-Dimer Test System is traceable to an in-house Master Calibrator.
  • Defined concentrations/levels: For precision studies, specific "samples" (likely control materials or spiked plasma) are used with known D-Dimer concentrations. For interfering substances, known concentrations of bilirubin, hemoglobin, rheumatoid factor, heparin, and lipids are added to samples.

8. Sample Size for the Training Set

Not applicable. This is an analytical immunoassay, not a machine learning model that requires a "training set" in the conventional sense of AI/ML algorithms. The development and optimization of the reagent and assay would involve various experimental and testing phases, but these are not referred to as training sets.

9. How the Ground Truth for the Training Set Was Established

Not applicable, as there is no "training set" in the context of an AI/ML algorithm. The calibration of the device is performed using a 6-point calibration curve, which is described as being traceable to an in-house Master Calibrator and aligned with another commercially available test system. This establishes the analytical accuracy of the measurements.

Dear Ms. Schwartz:

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, listing 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.

If you desire specific information about the application of labeling requirements to your device, or questions on the promotion and advertising of your device, please contact the Office of In Vitro Diagnostic Device Evaluation and Safety at (240) 276-0450.

§ 864.7320 Fibrinogen/fibrin degradation products assay.

(a)
Identification. A fibrinogen/fibrin degradation products assay is a device used to detect and measure fibrinogen degradation products and fibrin degradation products (protein fragments produced by the enzymatic action of plasmin on fibrinogen and fibrin) as an aid in detecting the presence and degree of intravascular coagulation and fibrinolysis (the dissolution of the fibrin in a blood clot) and in monitoring therapy for disseminated intravascular coagulation (nonlocalized clotting in the blood vessels).(b)
Classification. Class II (performance standards).
