Why get tested?

To detect and monitor muscle damage and to help diagnose conditions associated with muscle damage

When to get tested?

If you have muscle aches or pain, tenderness, weakness and swelling after muscle damage, particularly if your urine becomes dark reddish-brown in colour

Sample required?

A blood sample taken from a vein in the arm

Test preparation needed?


What is being tested?

This test measures the amount of creatine kinase (CK) in the blood. CK is an enzyme found in the heart muscle, brain tissue, skeletal muscle and other tissues. Increased amounts are released into the bloodstream when there is muscle damage. CK occurs in three major forms, called isoenzymes:

  • CK-MB (found mostly in heart muscle)
  • CK-BB (found mostly in brain tissue)
  • CK-MM (found in skeletal muscles)

How is the sample collected for testing?

A blood sample is taken by needle from the arm.

Is any test preparation needed to ensure the quality of the sample?

No test preparation is required.
