What does high creatine kinase mean?
CK stands for creatine kinase, an enzyme that leaks out of damaged muscle. When elevated CK levels are found in a blood sample, it usually means muscle is being destroyed by some abnormal process, such as a muscular dystrophy or inflammation.
What is a dangerous creatinine kinase level?
Clinical Significance of Raised Serum CK In the absence of specific myocardial or brain infarction, physical trauma, or disease, serum CK levels greater than 5,000 U/L are generally considered to indicate serious disturbance to muscle [10].
What does a creatine kinase blood test show?
A creatine kinase (CK) test may be used to detect inflammation of muscles (myositis) or muscle damage due to muscle disorders (myopathies) such as muscular dystrophy or to help diagnose rhabdomyolysis if a person has signs and symptoms.
What level of CK indicates heart attack?
To help differentiate heart attack from skeletal muscle damage, a CK index can be calculated using CK-MB and total CK as follows: CK index = (CK-MB, ng/mL) x100 / (total CK activity, IU/L). If CK-MB is elevated and the CK index in higher than 2.5 to 3.0, heart damage is likely.
What is a normal creatinine kinase level?
In a healthy adult, the serum CK level varies with a number of factors (gender, race and activity), but normal range is 22 to 198 U/L (units per liter). Higher amounts of serum CK can indicate muscle damage due to chronic disease or acute muscle injury.
Can high CK levels cause kidney damage?
Rhabdomyolysis caused by multiple factors is associated with exceptionally high CK levels. Higher CK levels are associated with greater burden on the kidneys, causing acute renal failure, severe electrolyte abnormalities, and acid base disturbances, resulting in significant morbidity.
What is a blood test for creatine kinase?
What is this test? This test measures the amount of an enzyme called creatine kinase (CK) in your blood. CK is a type of protein. The muscle cells in your body need CK to function.
Where does creatine kinase come from in the body?
Creatine kinase (CK) is an enzyme found in the heart, brain, skeletal muscle, and other tissues. Increased amounts of CK are released into the blood when there is muscle damage. This test measures the amount of creatine kinase in the blood. The small amount of CK that is normally in the blood comes primarily from skeletal muscles.
What happens when creatine kinase is too high?
Creatine kinase is an important enzyme needed for energy production and muscle function. Athletes have more of this enzyme in their blood, but so do obese and overweight people. High levels can tell us if there is muscle, heart, or brain damage.
What are the normal creatine kinase levels for African Americans?
CK levels are around 70% higher in healthy African Americans, compared to people of European descent! Some studies indicate that healthy black men and women can have significantly higher values than the currently recognized normal range (s) – up to 712 and 323 IU/L, respectively [ 5, 6, 7 ]. High Creatine Kinase Levels
What is this test? This test measures the amount of an enzyme called creatine kinase (CK) in your blood. CK is a type of protein. The muscle cells in your body need CK to function.
Where is creatine kinase found in the body?
This test measures the amount of creatine kinase (CK) in the blood. CK is a type of protein, known as an enzyme. It is mostly found in your skeletal muscles and heart, with lesser amounts in the brain. Skeletal muscles are the muscles attached to your skeleton. They work with your bones to help you move and give your body power and strength.

What does CK mean on MedlinePlus medical test?
Higher amounts can mean a health problem. Depending on the type and level of CK found, it can mean you have damage or disease of the skeletal muscles, heart, or brain. Other names: CK, total CK, creatine phosphokinase, CPK
