Intended Use
Immunoassay for the in vitro quantitative determination of troponin T in human serum and plasma. Elecsys Troponin T can be used as an aid in the differential diagnosis of acute coronary syndrome to identify necrosis, e.g., acute myocardial infarction. The test is further indicated for the risk stratification of patients presenting with acute coronary syndrome and for cardiac risk in patients with chronic renal failure. The test may also be useful for the selection of more intensive therapy and intervention in patients with elevated levels of cardiac Troponin T. The electrochemiluminescence immunoassay "ECLIA" is intended for use on the Roche Elecsys family of immunoassay analyzers.
Device Description
The Elecsys® Troponin T STAT assay is a two step sandwich immunoassay with streptavidin micro particles and electrochemiluminescence detection, for the measurement of human TnT in serum or plasma.

No
The summary describes a standard immunoassay and analyzer, with no mention of AI or ML in the intended use, device description, or performance studies.

No.
The device is used for in vitro quantitative determination of troponin T for diagnostic purposes, not for treating or preventing a disease.

Yes
The device is described as an "aid in the differential diagnosis of acute coronary syndrome to identify necrosis" and for "risk stratification," which are diagnostic purposes. It measures a biomarker (troponin T) to provide information about a patient's health status.

No

The device is an immunoassay reagent kit intended for use on specific hardware analyzers (Roche Elecsys family). It is a chemical 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 "Immunoassay for the in vitro quantitative determination of troponin T in human serum and plasma." The phrase "in vitro" is a key indicator of an IVD.
  • Device Description: The description details a "two step sandwich immunoassay" for the measurement of human TnT in serum or plasma, which are biological samples tested outside of the body.
  • Purpose: The test is used to aid in the diagnosis of acute coronary syndrome, risk stratification, and therapy selection, all of which are diagnostic purposes performed on samples taken from a patient.
