What is a normal creatine kinase level?
The short answer
A typical US lab prints a normal creatine kinase range for your sex: 26–192 U/L for women, 39–308 U/L for men. That range exists to catch disease, not to describe your best.
Nobody we follow has said what your Creatine Kinase should be. It comes up on the shows, but never with a number.
What Creatine Kinase measures
An enzyme your muscles release as they break down.
It rises after hard training or injury. What you did in the days before the draw changes what it means.
Checked against MedlinePlus — Creatine Kinase.
Common questions
What is a normal Creatine Kinase level?
Most US labs print 26–192 U/L. Your report grades you against that range. It exists to catch disease, not to describe your best. Labs print different ranges by sex: about 26–192 U/L for women and 39–308 for men.
What does your Creatine Kinase number mean?
On a typical lab range, under 26 U/L is low, 26 to 192 is normal and over 192 is high. Your own report prints its range next to your number, and that is the one your lab uses. Nobody we follow has drawn a line inside that range. Labs print different ranges by sex: about 26–192 U/L for women and 39–308 for men.
What does the Creatine Kinase test measure?
An enzyme your muscles release as they break down. It rises after hard training or injury. What you did in the days before the draw changes what it means.
Why is there no target here?
Because nobody we follow has named a number for Creatine Kinase. If that changes, it will be here.
