About test

Troponin I - Troponin I is part of a protein complex which regulates the contraction of striated muscle. In acute coronary syndromes (ACS), it can be detected in blood at 4-8 hours following the onset of chest pain, reaches a peak concentration at 12-16 hours, and remains elevated for 5-9 days. Troponin I has been used as a reliable marker in the diagnosis of perioperative myocardial infarction in patients undergoing cardiac surgery.
