About Troponin T (High-Sensitivity)
A troponin test measures the level of troponin in a sample of your blood. Troponin is a protein that's found in the cells of your heart muscle.
Normally, troponin levels in blood are so low that only the most sensitive types of tests can measure them. But if your heart muscle is damaged, troponin leaks into your bloodstream, and your troponin blood levels will rise.
Troponin testing is mainly used to help diagnose heart attacks. Heart attacks damage the heart by suddenly blocking the blood flow that brings oxygen to part of the heart muscle. Without oxygen from blood, heart muscle cells die and release troponin.
Troponin test results can confirm damage to the heart muscle from a heart attack. The more damage there is to the heart, the more troponin is released into the blood. So, measuring the amount of troponin in the blood can also help estimate how much of the heart has been damaged. Higher than normal troponin levels may also be found in other conditions that can damage heart muscle.
High-sensitivity troponin T testing can also be used to help estimate your overall risk of cardiovascular disease.

Useful for
Confirm if a person is having a heart attack or recently had a heart attack. This is the most common reason for troponin testing. The test is usually done in the emergency room of a hospital along with other heart tests, such as an EKG (also called an ECG or electrocardiogram).
Diagnose and monitor unstable angina. Angina is chest pain that happens if part of the heart muscle doesn't get as much blood as it needs. Unstable angina is a type of angina that happens at any time, even during rest. It's a medical emergency because it can lead to a heart attack.
Check heart health after a surgery that could damage the heart. In this case, a troponin test may be done before and after surgery so that the results can be compared.
Help estimate your overall risk of cardiovascular disease.

Interpretation
To understand the results of a troponin test for chest pain and/or other symptoms of a heart attack, your provider will consider your symptoms, medical history, and the results of other tests.
Higher than normal troponin levels don't always mean you've had a heart attack. They can be caused by unstable angina or many other conditions that can damage the heart.
If you have high troponin levels, but your provider doesn't think you've had a heart attack, you may have other tests to find the cause.
