More About the CK Blood Test

The creatine kinase test, also known as the CK test or CK blood test, measures the blood levels of creatine kinase. Creatine kinase is an enzyme that is associated with muscle damage and inflammation - a form of which is commonly known as rhabdomyolysis (rhabdo).

Creatine kinase plays an important role in helping muscles contract through the help of an energy source known as ATP. Creatine kinase in the blood can originate from different types of muscles and, historically, specific forms of it have been used to check for heart muscle damage after a heart attack.

CK blood testing has been of interest in recent years with the rise of organized fitness programs that center around intensive, shorter exercise regimens using higher intensity and heavier weights. In some people, such extreme exertion without proper training can lead to a condition called rhabdomyolysis. In rhabdomyolysis, excessive muscle damage can lead to kidney damage and is typically characterized by high creatine kinase and myoglobin test levels.
