What is a serum creatine kinase test?

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. Levels of CK can rise after a heart attack, skeletal muscle injury, or strenuous exercise.

What does a high creatine kinase level mean?

Creatine kinase or creatine phosphokinase is an enzyme chiefly found in the brain, skeletal muscles, and heart. An elevated level of creatine kinase is seen in heart attacks, when the heart muscle is damaged, or in conditions that produce damage to the skeletal muscles or brain.

What does a positive creatine kinase test mean?

If you have higher than normal CK-MM enzymes, it may mean you have a muscle injury or disease, such as muscular dystrophy or rhabdomyolis. If you have higher than normal CK-MB enzymes, it may mean you have an inflammation of the heart muscle or are having or recently had a heart attack.

What is a normal creatine kinase level?

That is why men usually have higher CK values than women. The low normal limit for both men and women is approximately 20 – 30 U/L (0.34 – 0.51 ukat/L). The upper normal limit for men is anywhere from 200 to 395 U/L (3.4 – 6.8 ukat/L) and for women, it’s up to 207 U/L (3.52 ukat/L) [3, 4, 5].

What level of creatine kinase 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 medications cause high creatine kinase?

Among the dehydrated wrestlers, the high level of serum CK would have affected their performance negatively as well as restricted their movements because of muscle pains.

Does vitamin D increase creatinine levels?

Vitamin D receptor activation has been associated with increased serum creatinine and reduced estimated glomerular filtration rates, raising concerns that its use may be detrimental to kidney function.

What medications affect creatinine?

Several drugs, such as cimetidine, trimethoprim, corticosteroids, pyrimethamine, phenacemide, salicylates and active vitamin D metabolites, have been reported to increase plasma creatinine without influencing its glomerular filtration.
