Intended Use
The CEDIA® Tacrolimus Assay is an in vitro diagnostic medical device intended for the quantitative determination of tacrolimus in human whole blood using automated clinical chemistry analyzers as an aid in the management of kidney and liver transplant recipients receiving tacrolimus therapy. CEDIA® Tacrolimus Calibrators are intended for calibration of the CEDIA® Tacrolimus Assay in whole blood.
Device Description
The CEDIA® Tacrolimus Assay uses recombinant DNA technology (US Patent No. 4708929) to produce a unique homogeneous enzyme immunoassay system. The assay is based on the bacterial enzyme ß-galactosidase, which has been genetically engineered into two inactive fragments i.e., enzyme acceptor (EA) and enzyme donor (ED). These fragments spontaneously reassociate to form fully active enzyme that, in the assay format, cleaves a substrate, generating a color change that can be measured spectrophotometrically. In the assay, analyte in the sample competes with analyte conjugated to one inactive fragment (ED) of ß-galactosidase for antibody binding site. If analyte is present in the sample, it binds to antibody, leaving the inactive enzyme fragments free to form active enzyme. If analyte is not present in the sample, antibody binds to analyte conjugated on the inactive fragment, inhibiting the reassociation of inactive ß-galactosidase fragments, and no active enzyme is formed. The amount of active enzyme formed and resultant absorbance change are directly proportional to the amount of analyte present in the sample.

No
The description details a homogeneous enzyme immunoassay based on recombinant DNA technology and spectrophotometric measurement. There is no mention of AI, ML, or any computational methods that would suggest their use in the device's operation or analysis.

No
This device is an in vitro diagnostic medical device used to measure tacrolimus levels in blood to aid in managing transplant recipients. It does not directly treat or prevent a disease.

Yes

Explanation: The "Intended Use / Indications for Use" section explicitly states "The CEDIA® Tacrolimus Assay is an in vitro diagnostic medical device intended for the quantitative determination of tacrolimus in human whole blood...".

No

The device description clearly outlines a chemical assay system involving enzymes, antibodies, and spectrophotometric measurement, indicating a hardware-based in vitro diagnostic device, not software only.

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

Here's why:

  • Intended Use: The "Intended Use / Indications for Use" section explicitly states that the CEDIA® Tacrolimus Assay is an "in vitro diagnostic medical device".
  • Purpose: The assay is designed to be used in vitro (outside the body) to analyze a human sample (whole blood) for the presence and quantity of tacrolimus.
  • Clinical Application: The results are intended to aid in the management of patients, which is a key characteristic of IVDs.

The description of the device and its mechanism further supports its classification as an IVD, as it describes a laboratory test performed on a biological sample.
