What is the Troponin I Test?
Troponin I is the most specific and sensitive marker for heart muscle damage. It's released into the bloodstream when heart muscle cells are injured — as in a heart attack. Troponin I stays elevated for 7-14 days after a cardiac event, making it useful for both early diagnosis and late presentation of heart attacks.
