Abstract: Objective To investigate the reason of increased level of creatine kinase-MB ( CK-MB) in patients with non-cardiac disease. Methods Clinical data of patients with normal level of CK and increased level of CK-MB were retrospectively analyzed. Results Out of 56 serum specimens with abnormal increase of CK-MB, 40 cases were from children, 8 cases from patients with cancer, 5 cases from patients with brain injury, 3 cases were hemolysis specimens. The average ratio of CK-MB/CK was 55.9% and 54.2% in specimen of cancer patients and hemolysis specimens, respectively. Conclusion Enzyme inhibition immunoassy may case false increase in levels of CK-MB among patients with non-cardiac disease.

Key words: Inhibition immunoassay, CK-MB, Non-cardiac
