About CPK
CPK is an enzyme released when muscle tissue is damaged, whether from an injury, intense exercise, a heart attack, or certain muscle diseases. Doctors use it to investigate unexplained muscle pain or weakness, or to assess heart muscle damage.
No fasting is required, and results are available the same day.
How to Prepare
- No fasting required.
- Avoid strenuous exercise for 24 hours before the test, since it can raise results.
