What no is considered high creatine kinase?

Creatine kinase (CK) levels can vary based on the laboratory and the specific assay used, but generally, a CK level above 200-300 U/L is often considered elevated in adults. Levels can be significantly higher in cases of muscle injury or disease. It’s important to interpret CK levels in the context of clinical symptoms and other diagnostic tests. Always consult a healthcare professional for personalized assessment and advice.
