Intended Use

The cassette Roche COBAS INTEGRA Carbon Dioxide (CO2-S) contains an in vitro diagnostic reagent system intended for use on COBAS INTEGRA for the quantitative determination of the carbon dioxide concentration in serum and plasma. Determination of carbon dioxide concentration in blood is most commonly performed as an initial test in the evaluation of the body's ability to control blood pH by appropriate removal of metabolism byproducts via the lung and kidneys. The cassette Roche COBAS INTEGRA Glucose HK Liquid contains an in vitro diagnostic reagent system intended for use on the COBAS INTEGRA for the quantitative determination of the glucose concentration in serum, plasma, urine and cerebrospinal fluid (CSF). In addition, an optional glucose "fast application" for serum and plasma is available. Glucose measurements are used in the diagnosis and treatment of carbohydrate metabolism disorders including diabetes mellitus and idiopathic hypoglycemia.

Device Story

COBAS INTEGRA Reagent Cassettes are in vitro diagnostic consumables used with the COBAS INTEGRA Analyzer. The analyzer utilizes absorbance, fluorescence polarization, and ion-selective electrodes to perform clinical chemistry, TDM, and hematology tests. Cassettes are loaded onto the analyzer, which uses barcode readers for identification and calibration. The system provides automated, random-access testing with a throughput of up to 600 tests/hour. Healthcare providers (laboratory technicians/pathologists) use the quantitative results to assess metabolic status, specifically blood pH regulation (CO2) and carbohydrate metabolism (glucose). The system streamlines workflow via robotics and integrated sample management, benefiting patients through rapid, accurate diagnostic data for clinical decision-making.

Clinical Evidence

Bench testing only. Performance evaluated via precision (within-run and total CV) and accuracy (correlation with predicate). CO2-S: n=220, r=0.999. Glucose HK Liquid (fast application): n=216, r=0.999. Results confirm performance is equivalent to legally marketed predicates.

Technological Characteristics

In vitro diagnostic reagent cassettes for use on the COBAS INTEGRA Analyzer. Methodology: Enzymatic (phosphoenolpyruvate carboxylase/malate dehydrogenase for CO2; hexokinase for glucose). System utilizes absorbance, fluorescence polarization, and ion-selective electrodes. Connectivity: Barcode-enabled for calibration/control data. Storage: 2-8°C on-board stability.

Indications for Use

Indicated for quantitative determination of carbon dioxide in serum/plasma and glucose in serum, plasma, urine, and CSF. Used for evaluating blood pH control and diagnosing/treating carbohydrate metabolism disorders like diabetes mellitus and idiopathic hypoglycemia.

Regulatory Classification

Identification

A bicarbonate/carbon dioxide test system is a device intended to measure bicarbonate/carbon dioxide in plasma, serum, and whole blood. Bicarbonate/carbon dioxide measurements are used in the diagnosis and treatment of numerous potentially serious disorders associated with changes in body acid-base balance.

#### IV. Description of the Device/Statement of Intended Use:

The COBAS INTEGRA test applications contained in this submission are 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 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℃. 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).
