Creatine Kinase (CPK)
Creatine kinase enters blood when muscle is stressed or damaged. Its level may help investigate muscle pain, weakness or a suspected medicine-related effect.

Understanding the test
What does the Creatine Kinase (CPK) test measure?
Also called Muscle & Heart Enzyme
CPK can help assess unexplained weakness or muscle pain, including in people taking a medicine that can affect muscle. Exercise and injuries are useful details to share.
When it may be requested
Muscle weakness or pain
The measurement can add information to the history and examination.
Monitoring a relevant medicine
When muscle symptoms develop during treatment, the clinician may check whether CPK is raised.
Before your sample
Prepare for collection
SpecimenSerum
Your checklist
Fasting is unnecessary. Avoid unusually vigorous exercise, heavy lifting and training for a few days before a planned baseline draw. Tell the team about muscle injury, injections, symptoms or statin treatment.
A clinician takes a small sample of blood from a vein. The laboratory uses serum, the liquid separated from the blood after it clots.

Reading your result
Higher levels may reflect muscle injury, but total CPK alone cannot locate it. The assessment also considers symptoms, kidney function and how the value changes.
What can affect it
- CPK alone neither locates a muscle injury nor excludes clinically important symptoms.

Patient questions
Before you book
Can a strenuous workout change my CPK?
Yes. Tell the clinician when you exercised and when symptoms started. The result alone cannot identify the cause or location of muscle injury.
What does a low CPK mean?
People with less muscle mass can have a lower baseline CK. If you are being tested for persistent weakness or pain, tell your clinician how the symptoms have changed. A low or normal total CK alone does not explain them.
Can a CPK test show which muscle is damaged?
No. Total CPK shows that muscle somewhere has released the enzyme, but not whether it came from skeletal muscle or the heart. Separating the two needs a different or additional test, and for chest pain troponin is the test that answers the question. Your doctor uses your symptoms and examination to work out the likely source.
After heavy exercise, when is it unsafe to wait for a CK test?
Seek immediate medical care if your muscles hurt much more than expected, you feel unusually weak, or your urine turns tea- or cola-coloured. These can be signs of rhabdomyolysis, a form of muscle breakdown that can injure the kidneys.
