No
The description details a standard immunoassay based on electrochemiluminescence detection and calibration curves, with no mention of AI or ML technologies.
No
The device is for in vitro quantitative determination of troponin T in human serum and plasma, which is a diagnostic purpose, not a therapeutic one. The description focuses on aiding diagnosis and monitoring, not on treating a disease.
Yes
The "Intended Use / Indications for Use" section explicitly states that the troponin T measurements "aid in both the early and late diagnosis of AMI" and that the "determination of cTnT in serum is an important component in the diagnosis of myocardial ischemia, e.g. AMI and myocarditis." These statements clearly indicate the device's role in diagnosing medical conditions.
No
The device description clearly indicates a hardware-based immunoassay system utilizing microparticles and electrochemiluminescence detection, which are physical components, not software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states "For the in vitro quantitative determination of troponin T in human serum and plasma." This clearly indicates that the device is used to test samples taken from the human body outside of the body (in vitro).
- Device Description: The description details an "immunoassay" and "electrochemiluminescence detection," which are common techniques used in laboratory testing of biological samples.
- Purpose: The purpose of measuring troponin T is to aid in the diagnosis and monitoring of conditions like AMI and unstable angina, which are medical diagnoses made based on laboratory results.
The information provided strongly aligns with the definition and characteristics of an In Vitro Diagnostic device.

Indications for Use
510(k) Number (if known):
Device Name: Boehringer Mannheim ® Elecsys Troponin T STAT
Indications for Use:
Troponin T (TnT) is a component of the contractile apparatus of the striated musculature. Although the function of TnT is the same in all striated muscles, TnT originating exclusively from the myocardium (cardiac TnT, molecular weight 39.7 kD) clearly differs from skeletal muscle TnT. As a result of its high tissue-specificity, cardiac troponin T (cTnT) is a cardiospecific, highly sensitive marker for myocardial damage. In cases of acute myocardial infarction, troponin T levels in serum rise about 3-4 hours after the occurrence of cardiac symptoms and can remain elevated for up to 14 days.
The determination of cTnT in serum is an important component in the diagnosis of myocardial ischemia, e.g. AMI and myocarditis, as well as in monitoring the course of unstable angina pectoris and assessing the associated risk. 1-6
Comparative studies on 770 patients confirm the prognostic utility of cTnT. It has also been shown that cTnT-positive patients benefit particularly from antithrombotic therapy strategies (e.g. low molecular weight heparin, BPIIb/IIIa antagonists). 8.9
Elevated serum cTnT values are detectable in about 30% of patients suffering from renal failure (e.g. chronic hemodialysis patients). The cTnT detected in these patients is of cardiac origin. It has been demonstrated e.g. with RT-PCR, that cTnT is not expressed in regenerated skeletal musculature of patients with renal failure. '611' Clinical data increasingly demonstrate that such patients have a high risk of subsequently suffering cardiovascular complications. 12-15
