NOTE: Multiple lab options. Use our Lab Locator to find closest.

Creatine Kinase (CPK, CK)

Laboratory: LabCorp
Creatine Kinase (CPK, CK)
Laboratory: Quest Diagnostics

Creatine Kinase is a protein that your muscles need in order to function. Levels of CK can become elevated due to muscle damage, heart attack, exercise, alcohol consumption or from certain medications or supplements. If muscle damage is suspected from an injury, this test may be ordered multiple times as it may take 48 hours for the CK level to rise.

This test may also be used to monitor continued muscle damage, such as for individuals that suffer from rhabdomyolysis. The CK test may be ordered with electrolytes and a metabolic panel to measure kidney function.
