Creatine Kinase Blood Test

Test for acute myocardial infarct and for skeletal muscular damage.

Creatine kinase blood test. High cpk levels can mean that a tissue has been damaged due to a person suffering a heart attack stroke or head injury. It is mostly found in your skeletal muscles and heart with lesser amounts in the brain. This test measures the amount of creatine kinase ck in the blood. Creatine kinase ck is an enzyme found in the heart brain skeletal muscle and other tissues.

Creatine kinase ck is an enzyme that catalyzes the reversible phosphorylation of creatine cr by adenosine triphosphate atp. Levels of ck can rise after a heart attack skeletal muscle injury strenuous exercise or drinking too much alcohol and from taking certain medicines or supplements. Increased amounts of ck are released into the blood when there is muscle damage. A cpk blood test checks for levels of creatine phosphokinase or creatine kinase in the blood.

What is a creatine kinase ck test. The small amount of ck that is normally in the blood comes primarily from skeletal muscles. 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. The muscle cells in your body need ck to function.

This test measures the amount of an enzyme called creatine kinase ck in your blood. 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. Ck is a type of protein. Elevated in some patients with myxedema hypothyroidism malignant hyperthermia syndrome and muscular dystrophy.
