What is the reference range for Troponin?

The reference range for troponin, a critical biomarker used in the diagnosis of myocardial injury, especially in conditions such as acute myocardial infarction, is typically between 0-0.03 ng/mL. This range indicates that troponin levels below this threshold are generally considered normal, meaning the heart muscle has not sustained significant injury.

Troponin is a protein complex found in cardiac muscle, and its measurement is pivotal in clinical settings to assess cardiac damage. When heart muscle cells are damaged, troponin is released into the bloodstream, leading to elevated levels that surpass the reference range.

Understanding what constitutes a normal troponin level is essential for interpreting test results effectively. A value exceeding this reference range would suggest myocardial injury, prompting further diagnostic actions and treatment considerations.
