The T-Tek Thrombin Time Reagent contains a lyophilized thrombin reagent, for use in the quantitative determination of thrombin time in citrated plasma. The thrombin time test is a one-stage quantitative test performed on diluted plasma samples in the general patient population. The thrombin time test is used to detect disorders of fibrinogen. The T-Tek, Thrombin Time Reagent should only be used in an appropriate clinical laboratory by qualified laboratory professionals.

The T-Tek Thrombin Time Reagent contains a lyophilized thrombin reagent, for use in the quantitative determination of thrombin time in citrated human plasma. The thrombin time test is a one-stage quantitative clotting test performed on citrated plasma samples in the general patient population. The thrombin time test is used to detect disorders of fibrinogen. The T-Tek, Thrombin Time Reagent should only be used in an appropriate clinical laboratory by qualified laboratory professionals. The test may be performed manually, or using semi-automated and automated coagulation analyzers.

Here's an analysis of the acceptance criteria and study proving device performance for the R2 Diagnostics T-Tek, based on the provided 510(k) premarket notification:

Note: This submission is for a medical reagent (thrombin time test) which typically focuses on chemical and functional equivalence to a predicate device, rather than the complex clinical performance metrics often seen with imaging AI devices. Therefore, some of the requested categories (e.g., MRMC studies, ground truth for training) are not directly applicable or explicitly detailed in this type of submission.
