Intended Use

The intended use of the Sysmex® CA-6000 is as a fully automated, computerized blood plasma coagulation analyzer for in vitro diagnostic use in clinical laboratories.

Device Story

Sysmex CA-6000 is a fully automated, computerized coagulation analyzer for clinical laboratory use. It processes citrated human plasma samples to perform clotting and chromogenic assays. The device measures coagulation parameters (e.g., PT, APTT, Fibrinogen, Factor assays) and calculates derived values (e.g., INR, activity percentages). Laboratory technicians operate the system to analyze patient samples. Results are provided to clinicians to assist in diagnosing and monitoring coagulation disorders. The device automates sample handling and measurement, reducing manual labor and improving consistency in coagulation testing compared to manual methods.

Clinical Evidence

Bench testing only. Method comparison studies evaluated 92 samples for Factor VIII and 128 samples for α2-Antiplasmin, showing strong correlation with the predicate device. Precision studies (n=40 per assay) demonstrated total %CV ranging from 2.3% to 7.9% across various control levels.

Technological Characteristics

Automated coagulation analyzer; utilizes citrated human plasma; performs clotting and chromogenic analysis; computerized data processing; intended for clinical laboratory environment.

Indications for Use

Indicated for in vitro diagnostic use in clinical laboratories to perform coagulation and chromogenic analysis on citrated human plasma samples. Parameters include PT, APTT, Fibrinogen (Clauss), Thrombin Time, Extrinsic/Intrinsic Factors, Batroxobin, Protein C, Antithrombin III, Plasminogen, and Factor VIII, along with various calculated ratios and activity percentages.

Regulatory Classification

Identification

A coagulation instrument is an automated or semiautomated device used to determine the onset of clot formation for in vitro coagulation studies.

Special Controls

*Classification.* Class II (special controls). A fibrometer or coagulation timer intended for use with a coagulation instrument 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

• Behring Coagulation Timer (BCT) (K955278)

As demonstrated by in-house correlation studies, the performance claims of the proposed device are similar to the predicate device. During those studies, specimens were evaluated from apparently healthy individuals and from patients with different pathological conditions which are expected to affect the results for a particular assay. The following summary shows the results of the comparison studies between the proposed and the predicate devices.
