Increased creatine kinase Increased creatine kinase concentration HP:0003525 Elevated circulating creatine kinase activity Increased creatine kinase level Elevated blood creatine phosphokinase Increased serum creatine kinase UMLS:C0241005 Elevated serum CPK Elevated creatine kinase level Elevated serum creatine kinase (CK) activity is usually an indicator of muscle damage. Diseases with very high CK values include subtypes of muscular dystrophies, idiopathic inflammatory myopathies and metabolic myopathies. However, a normal or only slightly elevated CK value does not exclude the presence of a myopathy. The normal range in the blood circulation is 34-171 U/l in males and 34-145 U/l in females, but may vary according to the test used.
