Special instructions

Avoid heavy exercise and eating meat-rich meals for 48 hours before your test.
This test measures the amount of creatine kinase (CK) in the blood. CK (creatine kinase) is an enzyme found in the heart, brain and skeletal muscle which signifies muscle cell damage and death. CK levels tend to be higher in people with greater muscle mass. The small amount of CK that is normally present in the blood comes primarily from skeletal muscles. Increased amounts are released into the bloodstream when there is muscle damage including strenuous exercise and muscle inflammation.
