Ck Levels Range. Different laboratories have different normal ranges reported in u l units per liter or ukat l microkatals per liter. The normal range for general ck varies by age and gender. The creatine kinase normal range varies from males to females. Creatine kinase ck is an enzyme that catalyzes the reversible phosphorylation of creatine cr by adenosine triphosphate atp.
Skeletal muscle expresses ck mm 98 and low levels of ck mb 1. How is this test done. For adult males the normal values are between 38 and 174 units per liter of blood whereas for adult females the normal level is between 90 and 140 units per liter of blood. Having a blood test with a needle carries some risks. Ck bb is predominantly expressed in brain and smooth muscle including vascular and uterine tissue. De visser in handbook of clinical neurology 2014.
This test is used to investigate cardiac or skeletal muscle pathology.
An elevation beyond this point is likely to be diagnostically relevant. Other tissues such as kidney have low levels of enzyme activity. The normal range for general ck varies by age and gender. Skeletal muscle expresses ck mm 98 and low levels of ck mb 1. People who have greater muscle mass have higher ck levels. Having a blood test with a needle carries some risks.
