The CK (Creatine Kinase) test measures the level of creatine kinase in your blood, an enzyme released during muscle damage. Elevated CK levels can indicate muscle injury, heart attack, or other conditions. This test is essential for individuals experiencing muscle pain or weakness and those monitoring heart health. Understanding your CK levels can help inform diagnosis and treatment decisions.

About This Test

Reason to Check It

"Creatinine Kinase (CK) is released from damaged or inflamed muscle cells.  Exercise and muscle trauma (contact sports, traffic accidents, intramuscular injections, surgery, convulsions, wasp or bee stings, and burns) and certain medications can elevate serum creatine kinase values. About 60% of hypothyroid subjects show an average elevation of CK activity 5-fold over the upper reference limit. 

Elevated CK levels in the hundreds (300-500’s) range are common in people who exercise while levels >1000 may indicate an autoimmune attack on your muscles (called inflammatory myositis).  Patients who have very high elevations of CK may suffer from constant muscle pain." - Dr. Alan Hopkins

Test Preparation

  • No special preparation is required before your sample collection.


Please Note: We recommend overnight fasting and an early morning blood draw for all tests, even if no special preparation is required. Remember, it is OK to drink plenty of water. Drinking water helps hydrate you and makes it easier for the phlebotomist to obtain your blood sample.
