A troponin test indicates what?

A troponin test indicates what?

• A. Detects kidney function
• B. Detects cardiac muscle injury
• C. Detects liver damage
• D. Detects lung infection

Answer: (B)

Troponin is a protein complex in cardiac muscle that controls contraction. When heart muscle is damaged, troponin I and troponin T spill into the bloodstream, so a troponin test measures those levels to indicate cardiac muscle injury. Elevated troponin is a key sign used to diagnose myocardial injury, such as a heart attack, and serial measurements help determine if injury is ongoing and guide treatment. This test does not assess kidney function, liver damage, or lung infection, which are evaluated with other specific tests and imaging.
