Troponin detects?

Troponin detects?

• A. It detects cardiac muscle injury
• B. It detects liver injury
• C. It detects skeletal muscle injury
• D. It detects kidney injury

Answer: (A)

Troponin is a biomarker of cardiac muscle injury. The cardiac forms (troponin I and troponin T) are released into the bloodstream when heart muscle cells are damaged, such as during a myocardial infarction. Because these isoforms are specific to heart tissue, elevated troponin levels strongly indicate heart muscle injury and help diagnose acute coronary syndromes. They aren’t used to detect liver, kidney, or skeletal muscle injury, which are assessed with other tests and biomarkers.
