The CPK Isoenzymes Test is also known as Creatine Kinase Isoenzymes, CK Isoenzymes, Creatine Phosphokinase Isoenzymes, and CK Fractionation. No fasting is required for this blood test, and results will be delivered within 1-2 days. This test does not require a doctorâs order or insurance.he CPK Isoenzymes Test measures total CK levels, plus percentage of each isoenzyme to help pinpoint the location of muscle damage. High CK-MB levels may indicate a myocardial infarction (heart attack) and can be used to estimate infarct size.
Creatine kinase is an enzyme that is present in all the muscles of the body and is a catalyst in the energy conversion process. Creatine kinase used in the body are of two types - for the muscles and for the brain. Any testing to check their levels will therefore have to factor in this difference and most will have a CKM or CKB test. Elevated levels of the enzyme, or any levels of it, is usually the first test for cardiac problems.
