Introduction
Blood CK refers to creatine kinase. Creatine kinase is primarily found in the myocardium and skeletal muscles of the body, and partially present in brain tissue and smooth muscle. Testing for creatine kinase helps doctors diagnose whether there are lesions in the myocardium, skeletal muscles, or related areas. If the test results show abnormally high or low levels, it is important to seek medical attention at a hospital promptly.
Generally, CK in a routine blood test refers to creatine kinase. The specific analysis is as follows:
Creatine kinase is primarily found in the myocardium and skeletal muscles of the body, with small amounts present in brain tissue and smooth muscle. Measuring creatine kinase levels helps doctors diagnose whether there are abnormalities in the heart or skeletal muscles. When measured using the enzyme-coupled method, the normal range for males is 38 U/L to 174 U/L, while for females it is 26 U/L to 140 U/L. A lower-than-normal level may result from prolonged bed rest or conditions such as hyperthyroidism leading to skeletal muscle atrophy. Elevated levels may indicate conditions such as acute myocardial infarction, viral myocarditis, or skeletal muscle injury. Both elevated and reduced levels require prompt medical treatment. However, since the underlying causes differ, treatment approaches will vary accordingly. It is important to seek timely medical evaluation and receive targeted treatment from a physician.
When undergoing a routine blood test, fasting for at least 8 hours is required. Eating before the test may affect the accuracy of the results.
