CPK isoenzymes test
CPK Isoenzymes Test
A CPK isoenzymes test is a blood test conducted to measure the levels of creatinine phosphokinase (CPK) isoenzymes in the body. CPK is a type of enzyme produced by different organs and tissues like the heart, skeletal muscle, and the brain. It is released into the blood when muscles are damaged or injured. In cases of cardiac problems, it helps to detect the presence of a heart attack. It’s also used to evaluate musculoskeletal disorders, blood clotting, and neurological problems.
Preparation
It usually takes about two hours for your body to process your blood sample before the CPK isoenzymes test is conducted. Therefore, you should do nothing to prepare for the test.
Procedure
The procedure for the CPK isoenzymes test is the same as for a standard blood test. A healthcare professional will use a needle to draw a blood sample from a vein in your arm. The blood sample is sent to a lab for testing.
Types
- CPK-1 (CK-MB): This type is found in the heart muscle, and is used for diagnosing cardiac events, like a heart attack.
- CPK-2 (MB): This type is found in the brain and it is primarily used to diagnose a stroke.
- CPK-3 (MM): This type is found in the skeletal muscle, and is used to detect muscle damage or disease.
Risks
There are very few risks associated with a CPK isoenzymes test. Possible risks may include: bruising at the needle site, lightheadedness, or fainting.
Why is the test conducted?
The CPK isoenzymes test is usually performed when the doctor suspects that there might be muscle damage or injury. It is also performed to measure the level of CPK in the blood when a heart attack or stroke is suspected.
When is the test conducted?
An elevated level of CPK isoenzymes may indicate an underlying condition, such as a heart attack, stroke, or muscle damage. So, the test is usually conducted when the doctor suspects that there might be an issue with the patient’s heart or muscles.
