What is a troponin test?A troponin test measures the level of troponin in your blood. Troponin is a type of protein found in the muscles of your heart. Troponin isn't normally found in the blood. When heart muscles become damaged, troponin is sent into the bloodstream. As heart damage increases, greater amounts of troponin are released in the blood.High levels of troponin in the blood may mean you are having or recently had a heart attack. A heart attack happens when blood flow to the heart gets blocked. This blockage can be deadly. But quick diagnosis and treatment can save your life.Other names: cardiac troponin I (cTnI), cardiac troponin T (cTnT), cardiac troponin (cTN),
cardiac-specific troponin I and troponin T
