Intended Use
The TROP method is used on the Dimension® RxL clinical chemistry system with the heterogeneous immunoassay module to quantitatively measure cardiac troponin-1 in human serum and plasma. Measurements of TROP aid in the diagnosis of myocardial infarction and in the risk stratification of patients with acute coronary syndromes with respect to their relative risk of mortality.
Device Description
The TROP method is a one-step enzyme immunoassay. Sample is incubated with chromium dioxide particles (CrOz) coated with a monoclonal antibody specific for cardiac troponin-1 and conjugate reagent [alkaline phosphatase (ALP) labeled monoclonal antibody specific for cardiac troponin-I] to form a particle/cardiac troponin-I/conjugate sandwich. Unbound conjugate and analyte are removed by magnetic separation and washing. The sandwich bound ALP initiates an amplification cascade. ALP dephosphorylates synthetic flavin adenine dinucleotide phosphate (FADP) to give FAD. FAD binds to APO D-amino acid oxidase and converts it to active holo D-amino acid oxidase. Each molecule of holo D-amino acid oxidase then produces multiple molecules of hydrogen peroxide (H2O2), which in the presence of horseradish peroxidase (HRP), converts 3,5-dichloro-2-hydroxybenzenesulfonic acid (DCHBS) and 4-aminoantipvrine (4-AAP) to a colored product that absorbs at 510nm. The color measured is directly proportional to the concentration of cardiac troponin-I present in the patient sample.

No
The description details a standard enzyme immunoassay method and does not mention any AI or ML components.

No
This device measures cardiac troponin-I to aid in the diagnosis of myocardial infarction and risk stratification; it does not provide therapy or treatment.

Yes
The device is described as aiding in the "diagnosis of myocardial infarction" and "risk stratification of patients with acute coronary syndromes," which directly indicates its use for diagnostic purposes.

No

The device description clearly outlines a chemical assay method involving reagents, particles, and enzymatic reactions, which are hardware components and chemical processes, not software.

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

Here's why:

  • Intended Use: The intended use explicitly states that the method is used to "quantitatively measure cardiac troponin-1 in human serum and plasma." This is a measurement performed in vitro (outside the body) on a biological sample.
  • Purpose: The measurements "aid in the diagnosis of myocardial infarction and in the risk stratification of patients with acute coronary syndromes." This clearly indicates a diagnostic purpose.
  • Device Description: The description details a laboratory-based immunoassay process involving chemical reactions and measurement of a colored product, which is characteristic of an in vitro diagnostic test.
  • Sample Type: The test is performed on "human serum and plasma," which are biological samples.

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.
