Creatine Kinase

A Creatine Kinase test measures the levels of creatine kinase in your blood. This enzyme is a high-energy substance used by our body to generate energy. It is found in our skeletal muscle, heart muscle, and brain. When any of these tissues are damaged, they release creatine kinase into your bloodstream. Repeated testing may also help monitor muscle damage or detect a subsequent or second heart attack early on.
