What Creatine Kinase measures
CK is an enzyme released from muscle. It rises after exercise, injury or some medications.
If your Creatine Kinase is low
Low CK is commonly associated with low muscle mass and is rarely notable.
Commonly associated with
- Low muscle mass
If your Creatine Kinase is high
CK above the range most often follows exercise or muscle injury; statins and thyroid function can also raise it.
Commonly associated with
- Recent exercise
- Muscle injury
- Statin medication
- Thyroid function
Typical reference range
| Group | Typical range |
|---|---|
| Women | 32 – 182 U/L |
| Men | 44 – 196 U/L |
Typical adult values used by many US labs. Your own report prints the range your lab validated for its method, and that range is the one that counts. Labwise always uses the printed range first.
If it is within range
Your creatine kinase is within the range printed by your lab.
