What is CK-MB test?

2Creatine Kinase-MB is a type of test carried out on a blood sample to determine the level of an isoenzyme of Creatine kinase present in the blood. Creatine kinase (CK) test is conducted to ascertain the level of Myocardial infarction or injury in the body.

What does the test entail?

The body is made up of 3 types of Creatine kinase (CK) which are present in the muscles, heart, tissues and some organs like the brain, uterus and the intestines. CK-MB is released into the blood as a result of injured or damaged heart via the heart muscle cells. A creatine kinase-MB (CK-MB) test is used to determine whether the increasing concentration of creatine kinase (CK) in the blood is as a result of heart or muscle damage.  This test could be required by your healthcare provider if you experience symptoms such as dizziness, excessive fatigue, nausea, a discomfort in the chest, shortness of breath, dizziness and extreme tiredness.  This test is commonly employed to detect potential or existing diseases associated with the heart.

 Why go for CK-MB test?3

This test is crucial in determining or detecting the presence of a muscle damage and ill heart; sometimes to determine if you have once experienced a heart attack and also to monitor for subsequent heart damage. This test is required if you experience signs or symptoms of heart dysfunction.

When is it ordered?

CK-MB test is needed when one experience frequent chest pain due to a high concentration level of creatine kinase in the blood and your doctor wants to be sure whether it is as a result of skeletal or heart muscle damage.

How do I get prepared for the test?

There is no special preparation required for this test. Make sure you inform your doctor or healthcare practitioner about the kind of medications you are taking which also includes illegal drugs you might be using.

4Sample needed?

Your blood sample will be collected into a specimen tube using a sterile needle, adequately labeled and sent to the lab for proper examination.

 Are there risks associated with CK-MB test?

Having your blood sample collected with a sterile needle could result in a slight bleeding, bruise and make you feel a light sharp pain when the needle goes down your vein.

What does my test result mean?

The standard normal level of CK-MB in the blood is 5 – 25IU/L for both male and female regardless of age making it undetectable or of extremely low concentration in the blood. A high concentration level of creatine kinase in the blood could indicate you have once experienced a heart attack or heart-related issues. High concentration of CK-MB could also be caused by muscle damage or diseases that cause harm to your muscle thereby affecting your chest.  Kidney failure, some rare chronic muscle disease, alcohol abuse can also alter the CK-MB concentration level.

Is there anything else I am supposed to know?

Heart or skeletal muscle damage contributes majorly to a high CK-MB level.  Your healthcare provider could ask you to go for other tests like an electrocardiogram, or ECG, to determine the electrical activity in your heart.
