Description:

The Troponin T test measures the levels of troponin T, a protein released into the blood when the heart muscle is damaged, typically due to a heart attack. It is a highly sensitive and specific marker used to diagnose acute coronary syndrome and myocardial infarction. Elevated troponin T levels indicate heart muscle injury, and the test helps in assessing the severity and timing of the damage. This test is critical in emergency settings for patients with chest pain or other symptoms suggestive of a heart attack.
