Measurements obtained by this device are used in the aid of diagnosis of diseases affecting iron metabolism in conjunction with other clinical and laboratory findings.
Device Description
The Tina-quant Ferritin Gen. 4 assay employs an immunoturbidimetric test in which human ferritin agglutinates with latex particles coated with anti-ferritin antibodies. The precipitate is determined turbidimetrically at 570/800 nm.
More Information

Not Found

No
The description details a standard immunoturbidimetric assay and does not mention any AI or ML components. The performance studies are based on traditional statistical methods.

No
The device is an in vitro diagnostic test used for aid in diagnosis, not for treating a disease or condition.

Yes
The "Intended Use / Indications for Use" section states that "Measurements obtained by this device are used in the aid of diagnosis of diseases affecting iron metabolism." This directly indicates its role as a diagnostic device.

No

The device description clearly indicates a physical assay employing latex particles and turbidimetric measurement, which are hardware components and processes, not solely software.

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 "Immunological in vitro immunoturbidometric test for the quantitative determination of ferritin in human serum and plasma". The phrase "in vitro" is a key indicator of an IVD.
  • Purpose: The intended use also states that the measurements are "used in the aid of diagnosis of diseases affecting iron metabolism in conjunction with other clinical and laboratory findings." This clearly indicates a diagnostic purpose.
  • Sample Type: The test is performed on "human serum and plasma," which are biological samples taken from the body, a characteristic of IVDs.
  • Device Description: The description details a laboratory test method (immunoturbidimetric test) performed on these samples.

All these elements align 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 a congenital abnormality, or to determine the compatibility with potential recipients, or to monitor therapeutic measures.

§ 866.5340 Ferritin immunological test system.

(a)
Identification. A ferritin immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the ferritin (an iron-storing protein) in serum and other body fluids. Measurements of ferritin aid in the diagnosis of diseases affecting iron metabolism, such as hemochromatosis (iron overload) and iron deficiency amemia.(b)
Classification. Class II (performance standards).
