A Creatine Kinase-MB Blood Test, also known as a CK-MB Test, can help determine whether a person has suffered a heart attack and if specific clot-dissolving drugs are working.
The CK-MB Test also goes by the following names: Creatine Kinase-MB, CK MB, CKMB, CPK-MB, CPK MB, CPKMB, and CK-2. No fasting is required for this blood test, and results will be delivered within 1-2 days.
The CK-MB Test is often ordered as a follow-up to a CPK Test if elevated levels of creatine kinase (CK) are present. The test can help determine whether the muscle damage detected in the CPK Test is to the heart or other muscles. If a doctor suspects a heart attack, the CK-MB Test can help verify the diagnosis and determine if the heart is damaged.
