The CPK blood test is a laboratory test that measures creatine phosphokinase (CPK), which is one of the enzymes found in the brain, heart, and skeletal muscles. This is a useful test for helping doctors to diagnose problems such as muscle damage, heart attack, and related conditions. slide 1 of 4.
Test results generally take between 24 to 72 business hours after your specimen is collected. Creatine kinase (CK) or Creatine phosphokinase (CPK) is an enzyme produced by the muscles. There are three types of CK produced by major muscle groups: the brain, the heart, and the skeletal muscle tissue. When muscle cells are injured or diseased, enzymes leak out of the cells and enter the bloodstream. Normally, very little CK is found circulating in the blood. Determining which type of CK level is high helps doctors determine which muscle has been damaged.
