Cpk-Mb

A CK-MB test is done urgently if you have chest pain or pressure, pain spreading to the arm, jaw, or back, shortness of breath, sweating, or nausea, the warning signs of a heart attack. Seek emergency care immediately if these occur. It is also used to detect a repeat heart attack and to monitor heart damage after cardiac procedures.

No special preparation or fasting is required for a CK-MB test. It is often done in an emergency, so never delay testing if you have chest pain. Inform your doctor about recent strenuous exercise, muscle injuries, intramuscular injections, surgery, or statin use, as these can raise CK levels. Repeat tests may be done several hours apart.

No, fasting is not required for a CK-MB test. It can be done at any time, regardless of meals, and is often performed in an emergency. If you have chest pain or other heart attack symptoms, don't delay; seek medical care immediately. Repeat tests may be needed several hours apart.
