Troponin - I

Troponin-I is a protein detectable in the blood only when there is an injury or stress to the heart muscles. It is not normally detectable in the blood. This protein plays a vital role in maintaining the heartbeat. The troponin-I test measures the amount of troponin-I protein in the blood and helps establish whether your symptoms are related to a heart problem. Also, this test helps evaluate individuals who have undergone surgery that can affect the heart. The troponin levels typically begin to increase within 2 to 3 hours after the onset of a heart attack. A heart attack happens when blood flow to the heart gets blocked. A quick diagnosis and treatment can help save your life.
