A blood sample is needed. This may be taken from a vein. The procedure is called a venipuncture.

This demo may be repeated over 2 or 3 days if you are a patient in the hospital.

No special preparation is needed most of the time.

Tell your health care provider about any medicines you are taking. Drugs that can increase CPK measurements include amphotericin B, certain anesthetics, statins, fibrates, dexamethasone, alcohol, và cocaine.

You may feel slight pain when the needle is inserted to lớn draw blood. Some people feel only a prichồng or stinging sensation. Afterward, there may be some throbbing.

When the total CPK level is very high, it most often means there has been injury or ức chế to lớn muscle tissue, the heart, or the brain.

Muscle tissue injury is most likely. When a muscle is damaged, CPK leaks inkhổng lồ the bloodstream. Finding which specific form of CPK is high helps determine which tissue has been damaged.

This demo may be used to:

Determine if or how badly a muscle is damaged

The pattern và timing of a rise or fall in CPK levels can be significant in making a diagnosis. This is particularly true if a heart attaông xã is suspected.

In most cases other tests are used instead of or with this demo khổng lồ diagnose a heart attaông chồng.

Total CPK normal values:

10 khổng lồ 1trăng tròn micrograms per liter (mcg/L)

Normal value ranges may vary slightly aao ước different laboratories. Some labs use different measurements or test different samples. Talk to your provider about the meaning of your specific thử nghiệm results.

High CPK levels may be seen in people who have:

Brain injury or strokeDelirium tremensDermatomyositis or polymyositisHeart attackInflammation of the heart muscle (myocarditis)Lung tissue death (pulmonary infarction)Muscular dystrophiesMyopathy

Other conditions that may give sầu positive demo results include:


Risks associated with having blood drawn are slight but may include:

Excessive bleedingFainting or feeling lightheadedHematoma (blood accumulating under the skin)Infection (a slight risk any time the skin is broken)

Other tests should be done to find the exact location of muscle damage.
