Creatine kinase (CK) measurement is specific for detection of cardiac muscle damage and used for diagnosis and monitoring of myocardial infarction.
|Adults||< 24 U/L||< 0.4 µkat/L|
Myocardial infarction: the risk of myocardial infarction is high if the following three conditions are fulfilled:
- CK (Men) > 190 U/L (3.17 μkat/L)**
CK (Women) > 167 U/L (2.78 μkat/L)**
- CK-MB > 24 U/L (0.40 μkat/L)**
- CK-MB activity is between 6 and 25 % of total CK activity.
** calculated using temperature conversion factor 2.38 (25 °C → 37 °C)
