Intended Use
VIDAS® Troponin I Ultra is an automated quantitative test for use on the VIDAS instruments for the determination of human cardiac troponin I in human serum or plasma (lithium heparin) using the ELFA (Enzymc-Linked Fluorescent Assay) technique. VIDAS Troponin I Ultra is intended to be used as an aid in the diagnosis of myocardial infarction.
Device Description
The VIDAS Troponin I Ultra (TNIU) Assay is an enzyme-linked fluorescent immunoassay (ELFA) performed in an automated VIDAS® instrument. All assay steps and assay temperature are controlled by the instrument. A pipette tip-like disposable device, the Solid Phase Receptacle (SPR), serves as the solid phase as well as a pipettor for the assay. Reagents for the assay are in the sealed TNIU Reagent Strips. The sample is transferred into the wells containing anti-cardiac troponin i antibodies labeled with alkaline phosphatase (conjugate). The sample/conjugate mixture is cycled in and out of the SPR for a specified length of time. Troponin I present in the specimen will bind to the anticardiac troponin i immunoglobulin coating the interior of the SPR. Unbound sample components are washed away. A fluorescent substrate, 4-methylumbellifery| phosphate, is introduced into the SPR. Enzyme remaining on the SPR wall will catalyze the conversion of the substrate to the fluorescent product 4-methylumbelliferone. The optical scanner in the instrument measures the intensity of fluorescence. When the VIDAS TNIU assay is completed, the results are analyzed automatically by the computer, a test value is generated, and a report is printed for each sample.

No
The description details a standard automated immunoassay system with automated analysis of results, but there is no mention of AI or ML algorithms being used for interpretation or analysis beyond basic calculation and reporting.

No
The device is an in vitro diagnostic test used to aid in the diagnosis of myocardial infarction by measuring cardiac troponin I levels, rather than directly providing therapy.

Yes

The "Intended Use" section explicitly states that the device "is intended to be used as an aid in the diagnosis of myocardial infarction."

No

The device description clearly outlines hardware components like the VIDAS instrument, Solid Phase Receptacle (SPR), and Reagent Strips, indicating it is not a software-only device.

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 VIDAS® Troponin I Ultra is an "automated quantitative test for use on the VIDAS instruments for the determination of human cardiac troponin I in human serum or plasma...". This clearly indicates that the device is used to test samples taken from the human body (in vitro) to provide diagnostic information.
  • Sample Type: The test is performed on "human serum or plasma," which are biological samples taken from a patient.
  • Diagnostic Purpose: The intended use also states it is "intended to be used as an aid in the diagnosis of myocardial infarction." This confirms its role in providing information for a medical diagnosis.
  • Device Description: The description details how the assay is performed using biological samples and reagents to measure a specific analyte (cardiac troponin I) for diagnostic purposes.

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

§ 862.1215 Creatine phosphokinase/creatine kinase or isoenzymes test system.

(a)
Identification. A creatine phosphokinase/creatine kinase or isoenzymes test system is a device intended to measure the activity of the enzyme creatine phosphokinase or its isoenzymes (a group of enzymes with similar biological activity) in plasma and serum. Measurements of creatine phosphokinase and its isoenzymes are used in the diagnosis and treatment of myocardial infarction and muscle diseases such as progressive, Duchenne-type muscular dystrophy.(b)
Classification. Class II.
