High Sensitivity Troponin: Definition, Clinical Significance, and Overview
High Sensitivity Troponin is a blood test used to detect very small amounts of cardiac troponin released with myocardial (heart muscle) injury. It is a diagnostic test in cardiology and emergency medicine, most often used when evaluating chest pain and suspected acute coronary syndrome (ACS). It supports early diagnosis and risk stratification for myocardial infarction (MI), alongside the electrocardiogram (ECG) and clinical assessment. It can also be elevated in non-ischemic conditions, so results must be interpreted in context.
