A creatine kinase (CK) test measures the amount of creatine kinase in your blood. Elevated CK levels may indicate skeletal muscle, heart or brain damage or degeneration — either chronic (long-term) or acute (short-term). Other names for a creatine kinase test include: CK total. CK creatine. Phosphokinase CPK.

2021年3月2日 · Exercise and training are the main cause of increased creatine kinase levels [10, 11, 12]. CK levels transiently increase to over 30 times the upper normal limit within 24 hours of strenuous physical activity and then slowly decline back to normal over the next 7 days.

肌酸激酶（Creatine Kinase，CK），也称为肌酸磷酸激酶。 肌酸激酶以骨骼肌、心肌、平滑肌含量为多，其次是脑组织，胃肠道、肺和肾内含量较少。 肌酸激酶主要存在于细胞质和线粒体中，是一个与细胞内能量运转、肌肉…

A CK test is mainly used to help diagnose and monitor injuries and diseases that damage skeletal muscles and cause high levels of CK in your blood. But it may also be used for conditions that damage the heart muscle and the brain.

2025年2月20日 · The creatine kinase test is a blood test that checks whether the CK levels in your blood are elevated. Elevated CK levels can mean you have some sort of muscle damage in your body. It doesn’t provide a full picture of your health, so healthcare providers typically perform other tests to make a diagnosis.

2021年1月4日 · An elevated level of creatine kinase, specifically CK-MB, occurs within hours of a heart attack as the heart muscle cells die. The enzyme level continues to rise for the first 18 to 24 hours after a heart attack and slowly returns to normal after a few days.

ck 是一種專門催化肌酸磷酸變為肌酸而產生能量供肌肉利用的一種酵素。 它大量存在於肌肉、腦、甲狀腺、紅血球中，因此肌肉方面的疾病如肌肉萎縮、多肌炎、皮肌炎、外傷、手術、肌肉過度使用等， CK 都會顯著上升。

2022年9月13日 · Creatine kinase (CK) is an enzyme found in the heart, brain, and skeletal muscle. High amounts of CK are released into the blood when there is muscle damage. A CK blood test may be used to detect inflammation of muscles (myositis) or muscle damage due to muscle disorders (myopathies).

CK is a marker for Duchenne muscular dystrophy, with elevations of 20 to 200 times normal. 1 CK is increased in female carriers of this X-linked disease, and in muscular stress, in polymyositis, dermatomyositis, and with muscle trauma. Elevated in myocarditis.

In quantitative total CK assays, macro CK is indistinguishable from normal CK and can cause an elevation of the total CK, although total CK may also be normal. Macroenzymes should be suspected when enzyme levels are persistently raised with relatively constant levels and there is no obvious clinical explanation or other laboratory abnormality.
