Creatine Kinase (CK Test) or Creatine Phosphokinase (CPK Test) Test
The enzyme, creatine phosphokinase(CPK) is found in the brain cells, the heart and the skeletal muscles. Any damage caused to the tissues in which CK is present results in the leakage of the enzyme into the blood. Therefore, the creatine kinase (CK) test is required, in order to measure the amount of CK in the blood.
Why is the test ordered?
The test may be ordered to detect
- Muscle damage
- Muscular dystrophy
- Inflammation of the muscles (myositis)
- Diseases of the connective tissues and muscles (dermatomyositis).
When is the test ordered?
A physician orders a CK test, if he or she suspects any muscle damage or muscle disease like muscular dystrophy in the patient’s body.The test may be ordered when a person suffers from severe injuries, trauma and extensive burns. The symptoms that are associated with muscle injury include muscle weakness, severe pain and dark urine.
How is the sample collected?
A blood sample is collected from a vein in the arm.
How to prepare for the test?
