This test measures creatine kinase (CK)‑MB, a CK isoenzyme, and may help assess patients with suspected acute coronary syndrome or reinfarction when troponin T and I testing are not available. CK‑MB is primarily found in cardiac tissue, with small amounts in skeletal muscle; measurement assists in differentiating myocardial injury from skeletal muscle sources.
