Creatine Kinase Isoenzymes (CK) Test

CK MM & BB & MB, CK fractionation, CPK Isoenzymes


Test Code: 002154
Specimen Type: Blood

Description:

Creatine Kinase Isoenzymes (CK) Test

This test measures levels of total Creatine Kinase (CK) as well as 3 CK Isoenzymes in the bloodCreatine Kinase is an enzyme which is produced when muscles are damaged.  A Total CK test can help to indicate muscle damage but it cannot identify where the damage has occurred.  Measuring the different isoenzymes of CK can help determine where in the body the damage is.   

  • CK-MM is found in skeletal muscles and the heart.  It can be elevated in cases of muscle damage, injury, inflammation, seizures, and skeletal muscle disorders.
  • CK-BB is mostly found in the brain and is elevated in conditions such as brain injury, stroke, and severe shock.
  • CK-MB is primarily found in the heart.  Increased CK-MB levels may indicate that a person has recently had a heart attack, especially if they are also experiencing chest pains. 

The CK Isoenzymes Panel also measures Macro CK type 1 and 2 if they are present.  These values can be related to a number of conditions which cause elevated CK and may help to further aid your doctor in making a diagnosis.

The CK Isoenzymes test may be ordered after a person has had abnormal results from a Creatine Kinase test.   It may also be ordered when someone has experienced symptoms of a heart attack or has inflammation, pain or muscle weakness.

Turnaround for this test is typically 1-3 business days.

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.

Requirements:

Exercising prior to blood draw may falsely elevate total CK levels.
