Device Story
COBAS INTEGRA system uses reagent cassettes for automated in vitro diagnostic testing; analyzer performs chemistry, drugs of abuse, immunology, and TDM assays. System utilizes absorbance, fluorescence polarization, and ion-selective electrodes; throughput up to 600 tests/hour. Reagent cassettes are barcode-identified, preparation-free, and stored on-board at 2-8°C. Input samples (serum, plasma, urine, CSF) are processed via robotics; analyzer provides quantitative or qualitative results to clinicians. System streamlines workflow via random access and STAT prioritization. Benefits include improved time management, reduced manual preparation, and consistent diagnostic accuracy for clinical decision-making.
Clinical Evidence
Bench testing only. Performance evaluated via precision (within-run and total CV%), sensitivity, and accuracy (correlation with predicate methods). Sample sizes ranged from 114 to 256. Correlation coefficients (r) were consistently high (0.973–0.999). Results confirm performance is equivalent to legally marketed predicate devices.
Technological Characteristics
Automated analyzer using absorbance, fluorescence polarization, and ion-selective electrodes. Reagents are liquid-based (previously granulate). Methodology includes enzymatic colorimetric, kinetic interaction of microparticles in solution (KIMS), and turbidimetric methods. System features barcode readers for reagent/sample identification, on-board refrigerated storage (2-8°C), and robotic sample handling. Connectivity includes automated data reading from cassette labels.
Indications for Use
Indicated for quantitative or qualitative in vitro diagnostic determination of analytes (Ammonia, Amylase, Cholesterol, HDL-Cholesterol, Creatinine, Digitoxin, GGT, Glucose, Lipase, LSD, Urea/BUN) in human serum, plasma, urine, or CSF. Used in clinical laboratory settings for patient monitoring and diagnostic testing.
Regulatory Classification
Identification

#### 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 96 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); and January 21, 1997 (K964457).
{3}------------------------------------------------
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).

Dear Ms. Feijoo:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions The general controls provisions of the Act of the Act. include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major requlations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical General requlation (21 CFR Part 820) and that, Devices: through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP requlation may result in regulatory In addition, FDA may publish further announcements action. concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal Laws or Requlations.

Under the Clinical Laboratory Improvement Amendments of 1988 (CLIA-88), this device may require a CLIA complexity categorization. To determine if it does, you should contact the Centers for Disease Control and Prevention (CDC) at (770) 488-7655.
This letter will allow you to begin marketing your device as described in your 510 (k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4588. Additionally, for question…
