what is a creatine kinase blood test
Creatine kinase also known as CPK or Creatine phosphokinase is an enzyme that is found in the brain, heart, and skeletal muscles. This enzyme encourages a particular biochemical reaction to occur. CK normally adds phosphate to creatine present in our body and turns it into molecule phosphocreatine which is high-energy.hen there is any muscle damage or degeneration the contents from the muscle cells break open and enter the bloodstream. As most of the CPK is found in the body, any increase found in the blood level during a creatine kinase blood test is indicative of muscle damage.
