What Is the Normal Level of Troponin Cardiac Enzyme?
Normal levels of the two types of troponin are less than 0.35 micrograms per liter of troponin I and less than 0.2 micrograms per liter of troponin T. Values and units for reporting the test results measuring cardiac enzymes vary considerably, according to WebMD.
This reference range can vary from lab to lab. Each lab report should state the range used by that lab. The doctor evaluates the results taking into consideration the patient's health and other factors. If the reported value falls outside this guideline, it may still be normal, according to WebMD. Consult the doctor concerning lab report results.
