Intended Use
The ARCHITECT Active-B12 (Holotranscobalamin) assay is a chemiluminescent microparticle immunoassay (CMIA) the for quantitative determination of Holotranscobalamin in human serum on the ARCHITECT i System. Active-B12 (Holotranscobalamin) is used as an aid in the diagnosis and treatment of vitamin B12 deficiency:
Device Description
The ARCHITECT Active-B12 (Holotranscobalamin) assay is a two-step immunoassay for the quantitative determination of Holotranscobalamin in human serum using CMIA technology, with flexible assay protocols, referred to as Chemiflex. In the first step, sample and anti-holotranscobalamin coated paramagnetic microparticles are combined. Holotranscobalamin present in the sample binds to the antiholotranscobalamin coated microparticles. After washing, anti-transcobalamin acridinium-labeled conjugate is added-to create a reaction mixture in the second step. Following another wash cycle, pretrigger and trigger solutions are added to the reaction mixture. The resulting chemiluminescent reaction is measured as relative light units (RLUs). A direct relationship exists between the amount of Holotranscobalamin in the sample and the RLUs detected by the ARCHITECT i System optics.
More Information

No
The description details a standard immunoassay technology (CMIA) and does not mention any AI or ML components in the assay or the system's operation.

No
This device is an in vitro diagnostic (IVD) assay used to aid in the diagnosis of vitamin B12 deficiency, not to treat it.

Yes

The intended use explicitly states that the device is "used as an aid in the diagnosis and treatment of vitamin B12 deficiency."

No

The device description clearly outlines a chemiluminescent microparticle immunoassay (CMIA) which involves physical reagents, microparticles, and a system (ARCHITECT i System) to measure relative light units. This is a hardware-based assay, not a software-only device.

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

Here's why:

  • Intended Use: The intended use explicitly states it's for the "quantitative determination of Holotranscobalamin in human serum" and is used "as an aid in the diagnosis and treatment of vitamin B12 deficiency." This clearly indicates it's used to test samples taken from the human body (in vitro) to provide information for medical diagnosis and treatment.
  • Device Description: The description details a "chemiluminescent microparticle immunoassay (CMIA)" that analyzes "human serum." This is a laboratory-based test performed on a biological sample outside of the body.
  • Performance Studies: The performance studies compare the device to a predicate device that is also an immunoassay, further confirming its nature as a diagnostic test performed on samples.

All of these points align with the definition of an In Vitro Diagnostic device.
