COBAS C111 ANALYZER PDF

Methods: Twenty-five frequently ordered analytes were evaluated relative to the published specifications of the cobas c Additionally correlation studies, using patient serum samples, were used to determine inter-instrument comparability between 2 cobas c instruments and accuracy relative to the standardized assays at LabCorp. Results: Precision, linearity, method comparison to another large Roche system, inter-instrument comparability, potential carryover, and time to result studies met or exceeded expectations. Additionally, sigma metrics analyses graded the overall performance of this analyzer as world class. Conclusions: The analytical performance, compact size, intuitive operation along with the expected low maintenance and reliability make the cobas c a good fit for the intended small laboratory niche environment at LabCorp. The cobas c is a bench-top system with a small footprint suitable for low volume laboratories with limited floor space.

Methods: Twenty-five frequently ordered analytes were evaluated relative to the published specifications of the cobas c Additionally correlation studies, using patient serum samples, were used to determine inter-instrument comparability between 2 cobas c instruments and accuracy relative to the standardized assays at LabCorp.

Results: Precision, linearity, method comparison to another large Roche system, inter-instrument comparability, potential carryover, and time to result studies met or exceeded expectations. Additionally, sigma metrics analyses graded the overall performance of this analyzer as world class.

Conclusions: The analytical performance, compact size, intuitive operation along with the expected low maintenance and reliability make the cobas c a good fit for the intended small laboratory niche environment at LabCorp.

The cobas c is a bench-top system with a small footprint suitable for low volume laboratories with limited floor space. The comprehensive test menu and easy integration of stat samples support testing of specialized assays, selected clinical panels, and rapid turnaround critical care markers. The intuitive user interface, barcode reader for samples, reagents and applications, and host connectivity option make the system very attractive in situations where operators may have minimal supervision and moderate skill sets.

Additionally, the cobas c uses the same bulk reagents as larger Roche systems currently used by LabCorp. This allows standardization of results across the LabCorp network or any other vertically integrated health care system that also selects the larger Roche platforms in their core laboratories.

The objective is to provide consistent patient results with the same reference ranges throughout the network regardless of the point of service. They are available as a liquid; 5—6 bottle sets from Maine Standards. Systems: The cobas c bench-top system is part of the cobas family of analyzers from Roche Diagnostics.

The system uses the same calibrators, controls, and reagents available on the larger Roche platforms and performance met or exceeded comparative expectations. Initial inspection of the precision data shows some between run coefficients of variation CVs that are unexpectedly less than the within run CV.

Inter-assay precision was performed by running each control level twice per day over 5 days and included 2 to 3 calibrations per analyte. Also included is a base matrix 0. Each level was analyzed in triplicate, and the mean value was compared to the expected value using regression analyses.

Analyte-specific sample sets were picked to challenge the measuring range. Both CA and CL show the effects of correlation data generated from specimens from a narrow distribution of values relatively to the expected 0 intercept. The CA slope of 1. Likewise the CL slope of 0. The DBIL slope of 0. Interference from bilirubin, lipids, or hemolysis was not evaluated as part of this study. The cobas c has the same optics as Integra, and the reagents, calibrators, and controls are largely the same across all Roche chemistry platforms, which is an important characteristic for vertically integrated organizations seeking standardization of testing throughout testing locations.
