Creatine Kinase

Test information: CK is present in many tissues but skeletal and heart muscles contain the highest concentrations. CK released from skeletal muscle accounts for almost all of the CK activity detected in the plasma of healthy individuals. Circulating CK is cleared by degradation in the liver and reticuloendothelial system and has a circulating half-life of 12 hours. Plasma CK levels are helpful in diagnosing rhabdomyolysis, because objective clinical signs are often absent.
