What is the CK-MB Test?

The CK-MB test measures a form of the enzyme creatine kinase found mainly in heart muscle. It rises in the blood a few hours after heart muscle is damaged. Today, troponin is the preferred blood test for a heart attack, and CK-MB is used alongside it in some situations.

MeasurementTypical adult value
Mass assayUsually below about 5 ng/mL
Activity assayUsually below about 25 U/L

CK-MB is reported in two different ways depending on the method: as mass (ng/mL) or as enzyme activity (U/L). The numbers are not comparable, so check the unit on your report and use its reference range.

Ranges differ between laboratories and methods. The reference range printed on your own report is the one to read your result against.

What your CK-MB Test result means

High
Suggests heart muscle injury, such as a heart attack or myocarditis. It can also rise with severe skeletal muscle injury, heavy exercise or kidney failure, so it is read with total CK and troponin.
Normal
Does not rule out a heart attack, especially in the first few hours. Troponin, repeated over time, is the test guidelines rely on.

One result is not a diagnosis. A doctor reads it with your symptoms, history, medicines and other tests.

Why is the CK-MB Test done?

  • Alongside troponin when a heart attack is suspected
  • Checking for a repeat heart muscle injury in the days after a heart attack
  • After heart procedures or surgery
  • Telling heart muscle injury apart from skeletal muscle injury

The reference interval printed on your actual laboratory report governs interpretation. Intervals can vary by laboratory, method, age, sex and pregnancy. Methods can also vary by processing laboratory.

  • No fasting is required. This test is usually ordered together with troponin to evaluate chest pain.

Frequently asked questions

I have chest pain now. Should I book a CK-MB test?
No. Chest pain that is new, severe or lasts more than a few minutes needs emergency care at the nearest hospital, where an ECG and troponin can be done at once. A scheduled lab test is not the right route.
What is the normal range for CK-MB?
It depends on the method. Mass assays are usually below about 5 ng/mL and activity assays below about 25 U/L. Use the unit and range printed on your report.
What is the difference between CK-MB and troponin?
Troponin is more specific to the heart and more sensitive, so the Fourth Universal Definition of Myocardial Infarction uses troponin to diagnose a heart attack. CK-MB falls back to normal within 2 to 3 days, which can help spot a second injury.
What is the difference between CPK and CK-MB?
CPK (or CK) is the total creatine kinase from all muscles. CK-MB is the heart-rich part of it. A high total CK with a normal CK-MB usually points to skeletal muscle rather than the heart.
How much does the CK-MB (Creatine Kinase MB) cost?
