Intended Use
Immunoturbidimetric assay for the quantitative in vitro determination of IgG in human serum, plasma and cerebrospinal fluid (CSF) on Roche automated clinical chemistry analyzers. Measurement of IgG aids in the diagnosis of abnormal protein metabolism and the body's lack of ability to resist infectious agents.
Device Description
The Tina-Quant ® IgG Gen.2 is an immunoturbidimetric assay for the quantitative in vitro determination of IgG in human serum, plasma and cerebrospinal fluid (CSF). Anti-IgG antibodies react with antigen in the sample to form an antigen/antibody complex which is measured turbidimetrically. The assay contains a standard application for measurement of IgG in human serum and plasma and a sensitive application for measurement of IgG in CSF.
More Information

No
The description focuses on a standard immunoturbidimetric assay and does not mention any AI or ML components.

No
This device is an in vitro diagnostic (IVD) assay used to measure IgG levels, which aids in diagnosis rather than directly treating or preventing a disease.

Yes

Explanation: The device is used to measure IgG levels which aids in the diagnosis of abnormal protein metabolism and the body's lack of ability to resist infectious agents. This indicates a diagnostic purpose.

No

The device is an in vitro diagnostic assay, which is a reagent-based test and not a software-only medical device.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The "Intended Use / Indications for Use" section explicitly states it is an "in vitro determination of IgG in human serum, plasma and cerebrospinal fluid (CSF)". This clearly indicates the test is performed outside of the body using biological samples.
  • Device Description: The "Device Description" further reinforces this by describing an "immunoturbidimetric assay for the quantitative in vitro determination of IgG".
  • Nature of the Test: The assay measures the concentration of IgG in biological fluids (serum, plasma, CSF) to aid in diagnosis. This is a hallmark of an in vitro diagnostic test.

The information provided aligns perfectly with the definition of an In Vitro Diagnostic device, which is a medical device intended for use in vitro for the examination of specimens derived from the human body solely or principally for the purpose of providing information concerning a physiological or pathological state, or concerning a congenital abnormality, or to monitor therapeutic measures.

§ 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)

Dear Dr. Ambrose:

This letter corrects our substantially equivalent letter of February 8,2005 regarding the Tina-Quant IgG Gen.2 in which the dates for submission and receipt were incorrectly entered as January 4 and January 6,2005 respectively.

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 (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 additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. 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
