Creatine Kinase Blood Test
Increased amounts of ck are released into the blood when there is muscle damage.
Creatine kinase blood test. This test measures the amount of an enzyme called creatine kinase ck in your blood. High cpk levels can mean that a tissue has been damaged due to a person suffering a heart attack stroke or head injury. The muscle cells in your body need ck to function. Creatine kinase ck is an enzyme that catalyzes the reversible phosphorylation of creatine cr by adenosine triphosphate atp.
Physiologically when muscle contracts atp is converted to adenosine diphosphate adp and ck catalyzes the rephosphorylation of adp to atp using creatine phosphate as the phosphorylation reservoir. This test measures the amount of creatine kinase in the blood. It is mostly found in your skeletal muscles and heart with lesser amounts in the brain. Ck is a type of protein.
What is a creatine kinase ck test. If your creatine kinase levels are high your doctor may order a creatine kinase isoenzyme tests to determine which type of creatine kinase enzyme is high 1 2. Test for acute myocardial infarct and for skeletal muscular damage. Creatine enzymes are released from muscles or tissues if they are injured damaged or die off.
Elevated in some patients with myxedema hypothyroidism malignant hyperthermia syndrome and muscular dystrophy. This test measures the amount of creatine kinase ck in the blood. A cpk blood test checks for levels of creatine phosphokinase or creatine kinase in the blood. The small amount of ck that is normally in the blood comes primarily from skeletal muscles.
