More in Heart Disease. Cardiac enzymes (the old name), or cardiac biomarkers (the new name), are blood tests that are used to detect damage to heart muscle cells. Cardiac biomarkers are proteins from heart muscle cells that have leaked out into the bloodstream after an injury to the cardiac muscle. Creatine kinase and troponin are the two proteins currently measured in biomarker tests.
What are normal cardiac enzyme levels? Quick Answer. Normal cardiac enzyme levels are between 0 and 3 for creatine kinase, between 0 and 3 nanograms per millimeter for creatine kinase-MB, less than 0.4 nanograms per millimeter for troponin and 38-120 nanograms per millimeter for total creatine kinase, according to the University of Minnesota.
