CPK isoenzymes test

A blood sample is needed. This may be taken from a vein. The test is called a venipuncture . If you are in the hospital, this test may be repeated over 2 or 3 days. A significant rise or fall in the total CPK or CPK isoenzymes can help your health care provider diagnose certain conditions.

No special preparation is needed in most cases. Tell your provider about all the medicines you are taking. Some drugs can interfere with test results. Drugs that can increase CPK measurements include the following: Alcohol Amphotericin B Certain anesthetics Cocaine Fibrate drugs Statins Steroids, such as dexamethasone…

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

This test is done if a CPK test shows that your total CPK level is elevated. CPK isoenzyme testing can help find the exact source of the damaged tissue. CPK is made of three slightly different substances: CPK-1 (also called CPK-BB) is found mostly in the brain and lungs CPK-2 (also called CPK-MB) is found mostly in…

Higher-than-normal CPK-1 levels: Because CPK-1 is found mostly in the brain and lungs, injury to either of these areas can increase CPK-1 levels. Increased CPK-1 levels may be due to: Brain cancer Brain injury (due to any type of injury including, stroke, or bleeding in the brain) Electroconvulsive therapy Pulmonary…

Factors that can affect test results include cardiac catheterization , intramuscular injections, recent surgery, and vigorous and prolonged exercise or immobilization. Isoenzyme testing for specific conditions is about 90% accurate.
