WHAT IS A CREATINE KINASE LAB TEST?
Creatine kinase (CK) or Creatine phosphokinase (CPK) is an enzyme produced by the muscles. There are three types of CK produced by major muscle groups: the brain, the heart, and the skeletal muscle tissue. When muscle cells are injured or diseased, enzymes leak out of the cells and enter the bloodstream. Normally, very little CK is found circulating in the blood. Determining which type of CK level is high helps doctors determine which muscle has been damaged.
WHY DO I NEED IT?
Are you experiencing unexplained chest pain or muscle weakness?
Abnormal levels of this enzyme can provide early warning of a muscular disease, such as Duchenne muscular dystrophy, evidence of a myocardial infarction or heart attack, or acute renal failure. If you are or have experienced chest pains the CK test can diagnose a heart attack. CK levels are also higher in women who carry the X-linked gene for Duchenne muscular dystrophy. An autoimmune disease that causes unexplained muscle weakness, swelling and damage called myositis can be detected with the CK test.
Men: 44-196 U/L
Women: 29-143 U/L
HIGH RESULTS INDICATE:
High results indicate damage to muscle tissue. These results may indicate heart attack (myocardial infarction), injury, severe muscle breakdown, muscular dystrophy, the autoimmune myositis (inflammatory muscle disease) or acute renal failure.
LOW RESULTS INDICATE:
Low levels of CK or CPK could indicate alcoholic liver disease or rheumatoid arthritis.
WHAT TYPE OF PHYSICIAN SHOULD I SEE IF MY TEST RESULTS ARE ABNORMAL OR OUT OF RANGE?
You should see your primary care physician.
