What is the CPK Test?

CPK (also called creatine kinase, CK) is an enzyme found mainly in muscle, the heart and the brain. When these tissues are damaged it leaks into the blood, so a raised CPK is a sign of muscle injury. It is used to look for muscle damage and to follow muscle disease.

CPK Test normal range

MeasurementTypical adult value
Adult menAbout 39–308 U/L
Adult womenAbout 26–192 U/L

Total CPK varies a lot with sex, muscle mass, ethnicity, recent exercise and the method used, and healthy people with large muscle bulk can sit above these figures. The range on your own report governs.

Ranges differ between laboratories and methods. The reference range printed on your own report is the one to read your result against.

What your CPK Test result means

High
Points to muscle damage. Common causes are hard exercise, injections, injury, statins, myositis, muscle diseases, an underactive thyroid and heart attack. Very high values with muscle pain and dark urine can mean rhabdomyolysis, which can injure the kidneys.
Low
Usually not significant. It can be seen with low muscle mass or long-term inactivity.

One result is not a diagnosis. A doctor reads it with your symptoms, history, medicines and other tests.

Why is the CPK Test done?

  • Muscle pain, weakness or dark urine
  • Suspected muscle inflammation (myositis) or muscular dystrophy
  • Muscle side effects in people taking statins
  • After crush injury, very heavy exercise or prolonged immobility
  • Chest pain evaluation, where CK-MB or troponin is used for the heart

The reference interval printed on your actual laboratory report governs interpretation. Intervals can vary by laboratory, method, age, sex and pregnancy. Methods can also vary by processing laboratory.

Sample: Blood. Fasting: Not required.

  • No fasting is required. Avoid strenuous exercise or intramuscular injections for 24 hours before the test, as these can raise the result.

Frequently asked questions

What is the full form of CPK?
CPK stands for creatine phosphokinase. It is the same enzyme as creatine kinase (CK), so a CPK test and a CK test are the same test.
What is a normal CPK level?
In adults it is roughly 39 to 308 U/L in men and 26 to 192 U/L in women, but it changes with muscle mass, exercise and the lab's method. Follow the range on your report.
Why is CPK high after exercise?
Hard or unaccustomed exercise causes small tears in muscle fibres, which release CPK. It may stay raised for several days. Avoid strenuous exercise for a day or two before the test unless your doctor says otherwise.
Is a high CPK a heart attack?
Not necessarily. Total CPK comes mostly from skeletal muscle. For the heart, doctors use troponin or CK-MB. Chest pain with sweating or breathlessness needs urgent medical care regardless of any CPK result.
Can statins raise CPK?
Yes. Statins can cause muscle pain and a raised CPK in some people. Do not stop a prescribed medicine on your own; talk to your doctor if you have unexplained muscle pain or weakness.
