Intended Use
Immunoturbidimetric assay for the in vitro quantitative determination of rheumatoid factors in human serum and plasma on automated clinical chemistry analyzers. Measurements may be used as an aid in the diagnosis of rheumatoid arthritis.
Device Description
The Tina-quant® Rheumatoid Factors II Test System is a particle enhanced immunoturbidimetric assay. Latex-bound heat inactivated IgG (antigen) reacts with the RF-antibodies in the sample to form antigen/antibody complexes which, following agglutination, are measured turbidimetrically.
More Information

Not Found

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

No
This device is an in vitro diagnostic assay used for quantitative determination of rheumatoid factors, which is an aid in diagnosis and not a therapeutic intervention.

Yes
The "Intended Use / Indications for Use" section explicitly states that "Measurements may be used as an aid in the diagnosis of rheumatoid arthritis," which indicates its role in diagnosis.

No

The device description clearly states it is a "particle enhanced immunoturbidimetric assay" and involves "Latex-bound heat inactivated IgG (antigen)" reacting with "RF-antibodies in the sample to form antigen/antibody complexes which, following agglutination, are measured turbidimetrically." This describes a chemical assay and a physical measurement process, not a software-only device.

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

Here's why:

  • Intended Use: The intended use explicitly states "in vitro quantitative determination of rheumatoid factors in human serum and plasma". This indicates the test is performed outside of the body using biological samples.
  • Device Description: The description details a "particle enhanced immunoturbidimetric assay" that measures "antigen/antibody complexes" formed by reacting the sample with reagents. This is a typical description of an in vitro diagnostic test.
  • Regulatory Context: The presence of a Predicate Device with a K number (K002609) strongly suggests this device has gone through a regulatory submission process for IVDs.

The information provided clearly aligns with the definition and characteristics of an In Vitro Diagnostic device.

§ 866.5775 Rheumatoid factor immunological test system.

(a)
Identification. A rheumatoid factor immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the rheumatoid factor (antibodies to immunoglobulins) in serum, other body fluids, and tissues. Measurement of rheumatoid factor may aid in the diagnosis of rheumatoid arthritis.(b)
Classification. Class II (performance standards).
