Most resources insist that creatine kinase is correct. See PMID:17174558 and PMID:14624200 not to mention Wikipedia. Creatine kinase is an enzyme found in the heart, brain, skeletal muscle, and other tissues. Increased amounts of CK are released into the blood when there is muscle damage. The small amount of CK that is normally in the blood comes primarily from skeletal muscles. increased circulating creatine phosphokinase level elevated circulating phospho-creatine kinase level elevated circulating CPK level increased circulating phospho-creatine kinase level MPheno.ontology elevated circulating creatine kinase level MP:0010090 elevated circulating creatinine kinase level increased circulating CPK level csmith increased circulating creatinine kinase level 2010-03-29T12:56:45Z increased circulating enzyme level increased creatine kinase level abnormal increased amount blood
