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 troponin levels in the blood may mean you have 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.
This test is most often used to diagnose a heart attack. It is sometimes used to monitor angina, a condition that limits blood flow to the heart and causes chest pain. Angina sometimes leads to a heart attack.
This test may also be used after you were diagnosed with a heart attack and admitted to a hospital. Testing is usually repeated two or more times in 24 hours. This is done to see if there are any changes in troponin levels over time.
