Immunoturbidimetric assay for the quantitative in vitro determination of IgG in human serum and plasma on Roche automated clinical chemistry analyzers. Measurement aids in the diagnosis of abnormal protein metabolism and the body's lack of ability to resist infectious agents.
The Tina-quant IgG Gen.2 is an immunoturbidimetric assay. Anti-IgG antibodies react with antigen in the sample to form an antigen/antibody complex which is measured turbidimetrically.
This is a request for information about a 510(k) submission for a medical device called "Tina-quant IgG Gen.2". The provided text is a 510(k) summary and the FDA's clearance letter. The document does not contain any information about acceptance criteria, device performance results, sample sizes for test or training sets, ground truth establishment, expert qualifications, adjudication methods, or MRMC studies.
The text describes an immunoturbidimetric assay for measuring IgG in human serum and plasma. It compares the new device (Tina-quant IgG Gen.2) to a predicate device (Tina-quant IgG, K955906) and highlights similarities and differences, primarily in measuring range and expected values for different age groups.
Therefore, I cannot provide the requested information based on the input text. The provided document is a regulatory filing, not a scientific study report detailing performance metrics against specific acceptance criteria.

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 recuirements, 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.

§ 866.5510 Immunoglobulins A, G, M, D, and E immunological test system.
(a)
Identification. An immunoglobulins A, G, M, D, and E immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the immunoglobulins A, G, M, D, an E (serum antibodies) in serum. Measurement of these immunoglobulins aids in the diagnosis of abnormal protein metabolism and the body's lack of ability to resist infectious agents.(b)
Classification. Class II (performance standards).
