The CPK test, also known as Creatine Phosphokinase (CPK) test, measures the level of the enzyme creatine phosphokinase (CPK) in the blood. CPK is an enzyme that is found in the heart, brain, and skeletal muscles. Elevated levels of CPK in the blood can indicate muscle damage or inflammation, and can also be an indicator of a heart attack.

Pre-test preparation:

There is no specific preparation required for a CPK test.

Testing method:

The CPK test is a blood test. A healthcare provider will take a sample of blood from the patient’s arm, usually from a vein in the elbow or the back of the hand. The blood sample will be sent to a laboratory for analysis.

Symptoms for prescribing this test:

The CPK test may be ordered if a person has symptoms of muscle pain, weakness or stiffness, or if they have a history of heart disease or risk factors for heart disease, or if they are experiencing chest pain or other symptoms of a heart attack.

Diagnosis:

CPK test results can be used, along with other tests such as troponin, to diagnose and monitor a heart attack, and to determine the extent of damage to the heart muscle. It can also be used to evaluate muscle damage or inflammation.

Reference range and normal values:

The normal range for CPK levels in the blood varies depending on the laboratory that performs the test, but it typically ranges between 30-200 IU/L for men and 20-90 IU/L for women.
