The cassette COBAS Integra Albumin Gen.2 (ALB2) contains an in vitro diagnostic reagent system intended for use on COBAS Integra systems for the quantitative determination of the albumin concentration in human serum and plasma. Albumin measurements are used in the diagnosis and treatment of numerous diseases involving primarily the liver or kidneys.

Device Description

The COBAS Integra Albumin Gen.2 is a colorimetric assay for the determination of albumin concentration in serum or plasma. At a pH value of 4.1, albumin displays a sufficiently cationic character to be able to bind with bromcresol green (BCG) to form a blue-green complex. The color intensity is directly proportional to the albumin concentration and can be determined photometrically.

AI/ML Overview

The provided text is a 510(k) Summary for the COBAS Integra Albumin Gen.2. It describes the device, its intended use, and claims substantial equivalence to a predicate device. However, it does not contain any information about acceptance criteria, device performance studies, sample sizes, expert ground truth, adjudication methods, or comparative effectiveness studies. The document primarily focuses on regulatory approval and equivalence to a previously marketed device.

Therefore, I cannot fulfill your request to describe the acceptance criteria and the study that proves the device meets the acceptance criteria, as this information is not present in the provided text.

Trade/Device Name: COBAS Integra Albumin Gen.2 Regulation Number: 21 CFR 862.1035 Regulation Name: Albumin test system Regulatory Class: Class II Product Code: CIX Dated: September 24, 2003 Received: September 26, 2003

Dear Ms. Coenen:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate 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) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions 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 (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820).

This letter will allow you to begin marketing your device as described in your Section 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 information about the application of labeling requirements to your device, or questions on the promotion and advertising of your device, please contact the Office of In Vitro Diagnostic Device Evaluation and Safety at (301) 594-3084.
