Clinical Significance
Serial quantitation of serum creatine kinase MB (CKMB) levels, often performed at admission and 8-hours, 16-hours, and 24-hours after admission, has traditionally been used as an aid in the diagnosis of myocardial injury.
May be useful if the initial troponin determination is abnormal or if a hospitalized patient has a suspected reinfarction.
