Creatine Kinase Conversion FAQ
Everything you need to know about converting and understanding Creatine Kinase (CK) lab results.
To convert Creatine Kinase from microkatals per litre (Ukat/L) to International Units per litre (IU/L), simply multiply the Ukat/L value by 60. For example, 1.5 Ukat/L is equal to 90 IU/L (1.5 × 60 = 90).
Both are units of enzyme activity, but they measure time differently. One microkatal (Ukat) represents the conversion of 1 micromole of substrate per second. One International Unit (IU or U) represents the conversion of 1 micromole of substrate per minute. Because there are 60 seconds in a minute, 1 Ukat equals 60 IU.
Normal reference ranges vary by laboratory, sex, and age. Generally, for adult males, the normal range is approximately 0.5 to 3.0 Ukat/L (30 to 180 IU/L). For adult females, it is typically lower, around 0.3 to 2.0 Ukat/L (20 to 120 IU/L). Always refer to the specific reference range printed on your lab report.
Elevated CK levels indicate muscle stress or damage. Common benign causes include intense physical exercise, heavy weightlifting, or recent intramuscular injections. Medical causes can include muscle injuries, certain medications (like statins), or conditions affecting the heart (e.g., myocardial infarction) or skeletal muscles. Always discuss elevated results with your doctor.
