The amount of creatine kinase (CK) in the blood is measured in this test. CK is an enzyme, which is a kind of protein. The majority of it is located in your skeletal muscles and heart, with smaller amounts in your brain. The muscles that are linked to your skeleton are known as skeletal muscles. They collaborate with your bones to aid movement and provide your body with power and strength. Blood is pumped in and out of the heart by cardiac muscles.
