Creatine Kinase (CK), Total

A creatine kinase (CK) lab test measures the total amount of creatine kinase enzyme in the blood, which is crucial for energy production in muscles. Elevated CK levels can indicate muscle damage or stress, as this enzyme is released into the bloodstream when muscle fibers are injured. This test is often used to diagnose conditions such as myocardial infarction (heart attack), muscular dystrophy, and rhabdomyolysis, a severe breakdown of muscle tissue. It can also help monitor muscle damage in athletes or those with muscle-wasting diseases. Abnormal CK levels necessitate further investigation to identify the underlying cause of muscle injury.
