There are 2 types of myofilament: a thick filament containing myosin and a thin filament consisting of 3 different proteins, namely actin, tropomyosin, and troponin. Troponin is itself a complex of 3 protein subunits, which are termed troponin T, troponin I, and troponin C:
Web• Class I: Cardiac-specific troponin (Troponin I or T when a contemporary assay is used) levels should be measured at presentation and 3 to 6 hours after symptom onset in all patients who present with symptoms consistent with ACS to identify a rising and or falling pattern.

WebMay 8, 2024 · National Center for Biotechnology Information WebJul 14, 2024 · The limit of detection of an hs-cTn assay is the lowest concentration of the analyte that can be detected. The limit of quantitation (LoQ) is the lower concentration of the analyte of which certainty can be quantified (i.e., with a coefficient of variation of 20%). The hs-cTn assays are only Food and Drug Administration–cleared to report the LoQ.
WebThe 99%ile of a normal population for this Trop T assay is 19 pg/mL. For patients who present with suspected ACS, a Trop T value > 19pg/mL with a rising pattern in serial samples is suggestive of ACS. Serial measurements are highly recommended for the diagnosis or exclusion of ACS.
