A few questions help us personalize your report.
Troponin I is a cardiac-specific protein released when heart muscle cells are damaged or destroyed. It is the gold-standard biomarker for diagnosing myocardial infarction. High-sensitivity assays detect extremely small amounts of cardiac injury, enabling earlier heart attack diagnosis and improving outcomes.
Also known as: Cardiac Troponin I, cTnI, High Sensitivity Troponin I, High-Sensitivity Troponin I, hs-cTnI, hs-TnI, hs-Troponin I, hsTroponin I
High Troponin I confirms cardiac myocyte damage from myocardial infarction, myocarditis, pulmonary embolism, or cardiac contusion. A rising-and-falling pattern is the hallmark of MI.
Normal is below 0.04 ng/mL. High-sensitivity assays detect below 0.01 ng/mL. Any detectable elevation warrants serial testing.
