## Indications for Use

The Triage D-Dimer Calibration Verification Controls are to be used with the Triage D-Dimer Test and Triage MeterPlus to verify the calibration of the Triage D-Dimer Test throughout the measurable range. The Triage D-Dimer Controls are assayed materials to be used with the Triage D-Dimer Test and Triage MeterPlus to assist the laboratory in monitoring test performance.

## Device Story

Triage D-Dimer Calibration Verification Controls and Triage D-Dimer Controls are liquid quality control materials; composed of EDTA human plasma with preservatives and D-dimer; used with Triage D-Dimer Test and Triage MeterPlus. Calibration verification controls supplied in five levels (A-E); Triage D-Dimer Controls supplied in two levels (1-2). Laboratory personnel use these assayed materials to monitor test performance and verify calibration throughout the measurable range. Product stability maintained at -20 °C or colder.

## Clinical Evidence

No clinical data. Bench testing only.

## Technological Characteristics

Liquid control material; EDTA human plasma base with preservatives and D-dimer; stored at -20 °C. Designed for use with Triage MeterPlus. No electronic or software components; purely chemical/biological control material.

## Regulatory Identification

A multipurpose system for in vitro coagulation studies is a device consisting of one automated or semiautomated instrument and its associated reagents and controls. The system is used to perform a series of coagulation studies and coagulation factor assays.

## Special Controls

*Classification.* Class II (special controls). A control intended for use with a multipurpose system for in vitro coagulation studies is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 864.9.

## Predicate Devices

- Bio-Rad Liquichek™ D-dimer Control Levels 1, 2 and 3 (k032017)

points using the Triage D-Dimer Controls. The % CV for the Level 1 control is 8.6% and the Level 2 control is 8.2%.

b. Linearity/assay reportable range:

Not applicable

c. Traceability, Stability, Expected values (controls, calibrators, or methods):

An open vial stability study was conducted to determine the stability of the control material once removed from frozen storage. Samples were thawed on a bench top with an ambient room temperature of 22 °C. Samples were tested on the same lot of randomized Triage devices at 10, 15, 20, 30, 60, 90 and 120 minutes. Samples were tested on 6 devices at each time point. Acceptance criterion for the study was defined as D-dimer values being within the expected range ± 2 standard deviations. Acceptable performance was obtained when the controls were thawed between 10-120 minutes with 30 minutes being the recommended time point for a thawed vial.

Closed-vial stability studies are continual and are used to determine product expiration dating. The Triage D-Dimer Calibration Verification Controls and the Triage D-Dimer Controls were stored at -20 °C and data generated over the initial 9 months indicated that D-dimer present in the Triage D-Dimer Calibration Verification Controls and the Triage D-Dimer Controls are stable for at least 9 months at -20 °C.
