What is hsTnT?

hsTnT stands for high sensitivity troponin T. Troponin T is a protein in the heart muscle which can be released into the blood when there is damage to the heart muscle as in a heart attack. Even small quantities of troponin T can be detected by a high sensitivity assay (laboratory estimation). hsTnT is more sensitive than conventional TnT estimation in detecting myocardial infarction (heart attack). The test is useful in diagnosing a heart attack in the emergency department for those with low and moderate risk of the disorder and presenting with chest pain. In a recent study, hsTnT could detect 27 percent more cases compared to convention troponin T.
