What are the lab results for creatine kinase?
Creatine kinase. A healthy result should fall into the range 24 – 204 U/L, 0.41 – 3.47 µkat/L, or 24.00 – 204.00 IU/L. Creatine kinase (CK) is an enzyme found primarily in the brain, skeletal muscles, and heart.
Can a stroke cause elevated creatine kinase level?
In some cases the test may be used to detect muscle conditions such as polymyositis (condition characterized by the inflammation of muscles) or to estimate the degree of muscle damage. Stroke and other forms of brain damage can also result in an elevated creatine kinase level.
How does CK catalyse the conversion of creatine?
CK catalyses the conversion of creatine and utilizes adenosine triphosphate (ATP) to create phosphocreatine (PCr) and adenosine diphosphate (ADP).
What causes low creatine kinase levels in muscle?
Causes of Low Creatine Kinase Levels 1) Low Muscle Mass The most common cause of low creatine kinase levels is muscle wasting (muscle atrophy) due to physical inactivity, illnesses, or old age [ 85 ]. 2) Inflammation in Autoimmune Disease
What does higher than normal CK-MB enzyme mean?
If you have higher than normal CK-MB enzymes, it may mean you have an inflammation of the heart muscle or are having or recently had a heart attack. If you have higher than normal CK-BB enzymes, it may mean you have had a stroke or brain injury.
What do the results of a CK test mean?
You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly. What do the results mean? If your results show you have a higher than normal level of CK, it may mean you have an injury or disease of the muscles, heart, or brain.
How is CK ‐ MB related to infarct size?
In a study of 65 patients with AMI, a single troponin T measurement obtained 72 hours after coronary care unit admission significantly correlated with peak CK‐MB in estimating infarct size ( r =0.76, P <0.001), using single‐photon emission computed tomography imaging as the gold standard. [ 12]
