The CK-MB test measures the concentration of creatine kinase in the blood. CK-MB is found predominantly in the heart and in small amounts in the skeletal muscles. CK-MB is released from the muscle cells into the blood during muscle damage. Blood has low levels of CK-MB, therefore an increase in CK-MB levels is indicative of heart damage.

The test results will vary depending on the sex, age, and health history. A high level of CK-MB indicates that you may have heart problems like myocarditis and pericarditis. It could also indicate that you have had a heart attack. Sometimes, a high CK-MB level can also occur because of chest trauma or damage elsewhere in the body.

The CK-MB normal range for adults is 24U/L and the CK value is >190 U/L (men) and >167U/L (women). If someone is suffering from myocardial infarction (heart attack), the CK-MB activity is in a range of 6-25% of the CK(total) activity. The heart is said to be damaged if the ratio of CK-MB total CK >2.5-3.

What does the CKMB Test Measure ?
The CK-MB test measures the concentration of creatine kinase in the blood. CKMB test is very important as it gives the right diagnosis to the doctor and makes it clear that the increase in kinase levels is due to heart attack or anything else.
Why should I do the CKMB Test ?
The CK-MB test is not a routine diagnostic test. An elevated CK can prompt your doctor to get you tested for CK-MB. The CK-MB test will help determine whether there is damage to your heart or other parts of the body. This test is needed if you have symptoms like muscle pain, numbness, and weakness. In simple language if you are showing signs of heart attack then the doctor, mostly cardiologist will order CKMB test along with Troponin test.
How is the CKMB Test Done ?
The CBC test is a simple blood test with no need for fasting before the test. The blood sample can be taken by the phlebotomist at a pathology lab or at home. At Maurya Labs the test is done on a Fully Automatic Analyzer. The sample collection takes less than a minute.
When should CKMB Test be Done ?
You will have to get a CK-MB test done if you have muscle pain, weakness, numbness, and balance problems. These symptoms indicate a muscle disorder. Healthcare providers also recommend a CK-MB test for stroke or other muscle injuries. The CK-MB levels take almost two days to rise. Thus, you may not get a result in one go and have to undergo testing multiple times. But this test will help the doctor determine heart damage.
