CK (Creatine Kinase)

Testing for CK levels is beneficial for individuals who may have experienced muscle damage, including those with symptoms of a heart attack or muscle diseases such as muscular dystrophy. It’s also important for people who have experienced physical trauma, prolonged muscle exertion, or seizures. Athletes engaged in intense physical training and individuals on certain medications that can affect muscle tissue, like statins, might also benefit from CK level monitoring.

• Muscle weakness or pain
• Dark urine (a sign of rhabdomyolysis, severe muscle breakdown)
• Symptoms of a heart attack, such as chest pain or shortness of breath, if the CK-MB isoenzyme is elevated
• General fatigue

To manage high CK levels, it’s important to address the underlying cause of muscle damage. This might include resting and recovering from muscle injury, adjusting medications that might be contributing to muscle damage, or treating specific conditions like myocardial infarction or muscular dystrophy. Adequate hydration is important, especially in cases of rhabdomyolysis.

Several factors can influence CK levels. Physical trauma or injury to the muscles can cause a significant increase in CK. Intense exercise, especially in untrained individuals or those undertaking unusual exertion, can elevate levels. Certain medications, particularly statins, can increase CK. Medical conditions like myocardial infarction, muscular dystrophy, and other muscle diseases can cause elevated CK levels. Age, gender, and muscle mass can also affect baseline CK levels.
