The troponin cardiac test measures high-sensitivity troponin T, a protein found in heart muscle that is released into the blood when heart muscle is damaged. It is one of the most important blood markers used to evaluate a possible heart attack and to detect other causes of cardiac injury. Because levels can change quickly, the test is often repeated over a few hours to look for a rise or fall. Results are interpreted with symptoms, an electrocardiogram, and other cardiac testing.

• High-Sensitivity Troponin T A heart muscle protein measured in blood to detect cardiac injury; rising levels can indicate heart damage.

• People with chest pain or pressure
• Individuals with shortness of breath or other possible heart attack symptoms
• Patients being evaluated for heart muscle injury
• People with known heart conditions being monitored

• No fasting is usually required
• Tell the provider about chest pain timing and any heart procedures
• Report kidney disease, which can affect troponin levels
• Serial samples may be requested over several hours

A rising or high troponin level indicates heart muscle injury, which may be caused by a heart attack or other conditions such as severe heart strain, kidney disease, or inflammation. A normal level with repeat testing can help rule out an acute heart attack. Results are always interpreted with symptoms, ECG, and imaging. Seek emergency care for chest pain and discuss your troponin results with a healthcare provider.
