Finecare Troponin-T refers to a diagnostic test that uses a quantitative immunoassay to measure the levels of cardiac troponin T (cTnT) in human blood, serum, or plasma, primarily as an aid in the diagnosis of myocardial infarction (heart attack). Troponin T is a protein found in heart muscle cells, and elevated levels in the blood indicate damage to the heart, with higher values suggesting a greater likelihood of a heart attack.
