No
The device description details a standard immunoassay method based on chemical reactions and optical detection, with results determined via a calibration curve. There is no mention of AI or ML in the description, performance studies, or key metrics.

No
The device measures vitamin B12 levels for diagnosis and treatment of anemias, but it does not directly treat or restore health.

Yes

The "Intended Use / Indications for Use" states that "Measurements obtained by this device are used in the diagnosis and treatment of anemias of gastrointestinal malabsorption," which clearly indicates its use as a diagnostic device.

No

The device description details a complex chemical assay process involving reagents, incubations, microparticles, and a chemiluminescent detection system with a photomultiplier. This clearly indicates a hardware-based in vitro diagnostic device, not a software-only device.

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

Here's why:

  • Intended Use: The intended use explicitly states that the device is "intended to measure vitamin B12 in serum, plasma, and urine" and that these measurements "are used in the diagnosis and treatment of anemias of gastrointestinal malabsorption." This clearly indicates that the device is used to examine specimens derived from the human body for the purpose of providing information for the diagnosis and treatment of a disease.
  • Device Description: The description details a laboratory-based assay process involving chemical reactions and measurement of a substance (vitamin B12) in biological samples (serum, plasma, urine). This is characteristic of an in vitro diagnostic device.
  • Performance Studies: The performance studies compare the device to a predicate device (BioRad Quantaphase II B12/Folate Radioassay) which is also an IVD. The metrics evaluated (Precision, Lower Detection Limit, Linearity, Method Comparison) are standard for evaluating the performance of IVD assays.

Based on the provided information, the device meets the definition of an In Vitro Diagnostic device.
