Troponin I, High Sensitivity
Also known as: Troponin HS, High Sensitivity
Use
Troponin I, a component of the troponin complex, serves as a highly specific and sensitive biomarker of cardiac muscle injury. Elevated concentrations of troponin I in plasma or serum are indicative of myocardial injury, including acute coronary syndromes. High‑sensitivity assays enable detection of minimal elevations, essential for early diagnosis and risk stratification in patients presenting with chest pain or suspected cardiac events.
Special Instructions
Not provided.
Limitations
Non‑acute coronary syndromes (e.g., myocarditis, renal impairment, sepsis) may cause elevated troponin I levels, limiting specificity for myocardial infarction. Interpret results within clinical context and in conjunction with serial measurements.
