Creatine Kinase Test
Elevated in some patients with myxedema hypothyroidism malignant hyperthermia syndrome and muscular dystrophy.
Creatine kinase test. What is a creatine kinase ck test. Increased amounts of ck are released into the blood when there is muscle damage. Creatine kinase ck is an enzyme that catalyzes the reversible phosphorylation of creatine cr by adenosine triphosphate atp. Ck is a type of protein known as an enzyme.
The small amount of ck that is normally in the blood comes primarily from skeletal muscles. Creatine kinase ck is an enzyme found in the heart brain skeletal muscle and other tissues. This test measures the amount of creatine kinase in the blood. A cpk isoenzymes test can detect various muscle diseases or issues including.
This test measures the amount of creatine kinase ck in the 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. This test measures the amount of an enzyme called creatine kinase ck in your blood. The muscle cells in your body need ck to function.
It is mostly found in your skeletal muscles and heart with lesser amounts in the brain. Ck is a type of protein. 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.
