CK-NAC

Measurement of CK is used especially in conjunction with CK-MB for diagnosis and monitoring of myocardial infarction.

Reference Ranges

Adults
Women< 145 U/L< 2.42 µkat/L
Men< 171 U/L< 2.85 µkat/L
These reference ranges ensure high diagnostic sensitivity. The diagnostic specificity is low; however, it can be improved by additional measurement of CK-MB.
Children
Umbilical cord blood175 - 402 U/L2.92 - 6.70 µkat/L
Newborns468 - 1200 U/L7.80 - 20.0 µkat/L
≤ 5 days195 - 700 U/L3.25 - 11.7 µkat/L
< 6 months41 - 330 U/L0.68 - 5.50 µkat/L
> 6 months24 - 229 U/L0.40 - 3.82 µkat/L
Each laboratory should check if the reference ranges are transferable to its own patient population and determine own reference ranges if necessary. For diagnostic purposes, the results should always be assessed with the patient’s medical history, clinical examinations and other findings.
