Device Description
The COBAS INTEGRA HDL-D reagent cassette is intended for use with the COBAS INTEGRA Analyzer. The COBAS INTEGRA Analyzer and COBAS INTEGRA Reagent cassettes together provide an integrated system for in vitro diagnostic testing. The COBAS INTEGRA Analyzer utilizes three measuring principles, i.e., absorbance, fluorescence polarization and ion-selective electrodes. The analyzer has a throughput of up to 600 tests per hour with STAT samples prioritized and tested immediately. Random sample access, robotics and a user interface optimize time management and streamline workflow. The COBAS INTEGRA can store up to 68 COBAS INTEGRA Reagent Cassettes on board, 24 hours a day at 2-8°C. The COBAS INTEGRA Reagent Cassettes are compact and preparation-free with the added convenience of long term on-board stability. Barcode readers are used to identify newly loaded reagent cassettes, samples for patient identification, and rack inserts and to read calibration and control data from the cassette label. COBAS INTEGRA tests include chemistry, drugs of abuse, immunology, ion selective electrodes, therapeutic drug monitoring, and hematology reagents.
The principle of the COBAS INTEGRA HDL-D reagent cassette is based on the absorption of synthetic polyanions to the surface of lipoproteins. LDL, VLDL, and chylomicrons are transformed into a detergent-resistant form. whereas HDL is not. Combined action of polyanions and detergent solubilizes cholesterol from HDL, but not from LDL, VLDL, and chylomicrons. Solubilized cholesterol is oxidized by the sequential enzymatic action of cholesterol esterase and cholesterol oxidase. The hydrogen peroxide produced in this reaction is reacted with chromogens to form a colored dye. The increase in absorbance at 552 nm is directly proportional to the HDL cholesterol concentration of the sample.

The COBAS INTEGRA HDL-D Reagent Cassette is substantially equivalent to the currently marketed COBAS INTEGRA HDL reagent system (K951595).
Description of the Device/Statement of Intended Use: IV.
The COBAS INTEGRA HDL-D reagent cassette is intended for use with the COBAS INTEGRA Analyzer. The COBAS INTEGRA Analyzer and COBAS INTEGRA Reagent cassettes together provide an integrated system for in vitro diagnostic testing. The COBAS INTEGRA Analyzer along with 107 other Roche COBAS INTEGRA Reagent Cassettes were previously cleared on September 8, 1995 (K951595); January 25, 1996 (K954992); July 23, 1996 (K961824); October 31.1996 (K963292); January 21, 1997 (K964457) and August 12, 1997 (K972250).
The COBAS INTEGRA Analyzer utilizes three measuring principles, i.e., absorbance, fluorescence polarization and ion-selective electrodes. The analyzer has a throughput of up to 600 tests per hour with STAT samples prioritized and tested immediately. Random sample access, robotics and a user interface optimize time management and streamline workflow. The COBAS INTEGRA can store up to 68 COBAS INTEGRA Reagent Cassettes on board, 24 hours a day at 2-8°C. The COBAS INTEGRA Reagent Cassettes are compact and preparation-free with the added convenience of long term on-board stability. Barcode readers are used to identify newly loaded reagent cassettes, samples for patient identification, and rack inserts and to read calibration and control data from the cassette label. COBAS INTEGRA tests include chemistry, drugs of abuse, immunology, ion selective electrodes, therapeutic drug monitoring, and hematology reagents. For additional information on the COBAS INTEGRA Analyzer and its constituent modules, please refer to the Operator's Manual in Volumes 1 through 2, pages 92-703, of the original 510(k) submission (K951595).
Through this submission, it is the intention of Roche Diagnostic Systems to gain clearance for the COBAS INTEGRA HDL-D Cassette.
The COBAS INTEGRA HDL-D reagent cassette is an in vitro diagnostic reagent system intended for use on COBAS INTEGRA for the quantitative determination of High Density Lipoprotein cholesterol direct (HDL-D) in serum and plasma.
Low HDL levels are recognized as a strong and common risk factor for atherosclerotic Coronary Artery Disease (CAD). Therefore, determination of HDL cholesterol is routinely offered as part of a lipid profile. Usually VLDL and LDL are selectively precipitated from serum or plasma samples followed by determination of cholesterol in the HDL - containing supernatant. These techniques require a centrifugation step to remove the precipitated lipoproteins and thus cannot be fully automated. The COBAS INTEGRA HDL - Cholesterol Direct, however, allows for the
3
direct specific determination of HDL cholesterol in the presence of LDL. VLDL and chylomicrons without any sample pretreatment. Therefore, lending itself to automated routine analysis.
The principle of the COBAS INTEGRA HDL-D reagent cassette is based on the absorption of synthetic polyanions to the surface of lipoproteins. LDL, VLDL, and chylomicrons are transformed into a detergent-resistant form. whereas HDL is not. Combined action of polyanions and detergent solubilizes cholesterol from HDL, but not from LDL, VLDL, and chylomicrons. Solubilized cholesterol is oxidized by the sequential enzymatic action of cholesterol esterase and cholesterol oxidase. The hydrogen peroxide produced in this reaction is reacted with chromogens to form a colored dye. The increase in absorbance at 552 nm is directly proportional to the HDL cholesterol concentration of the sample.
V. Summary of the technological characteristics of the new device in comparison to those of the predicate.
The COBAS INTEGRA HDL-D reagent cassette is similar to the COBAS INTEGRA HDL reagent system in that HDL cholesterol is quantitated using an enzymatic, colorimetric method (CHOD/PAP).
The differences are that the current COBAS INTEGRA HDL application requires pretreatment of the sample with a separating reagent prior to analysis whereas the COBAS INTEGRA HDL-D reagent cassette measures the HDL cholesterol concentration directly in the sample.
The current COBAS INTEGRA HDL reagent application is used in conjunction with the Roche HDL Cholesterol Precipitating Reagent and the COBAS INTEGRA Cholesterol reagent cassette (K951595). The Roche HDL Cholesterol Precipitating Reagent uses phosphotungstic acid and magnesium ions to precipitate the chylomicrons, VLDL, and LDL. After centrifugation, HDL remaining in the supernatant is quantitated by its cholesterol content using an enzymatic. colorimetric method (CHOD/PAP).
A summary of the similarities, differences and performance characteristics between the COBAS INTEGRA HDL-D reagent cassette and the COBAS INTEGRA HDL reagent system are listed in Table 2.
