CPK Muscle Enzyme Test in Johor Bahru

Ujian Enzim Otot CPK

Creatine phosphokinase (CPK), also called creatine kinase (CK), is a muscle enzyme that rises significantly when muscle tissue is damaged. Klinik Muhibbah offers CPK blood testing for patients with unexplained muscle pain, weakness, dark urine after exercise, statin medication side effects (statin-induced myopathy), or suspected rhabdomyolysis. CPK is also used to monitor athletes and workers in physically demanding occupations.

How to Prepare

Frequently Asked Questions

Why would a doctor order a CPK test?▼

CPK testing is ordered when a patient has unexplained muscle pain, weakness, or cramps; dark or cola-coloured urine after exertion (suggesting rhabdomyolysis); is on statin medication and reporting muscle symptoms; or has suspected inflammatory muscle disease (myositis). It is a key test in muscle disease evaluation.

Can statin medications cause high CPK?▼

Yes, statins (cholesterol-lowering medications) can cause statin-induced myopathy — muscle inflammation and damage — in a small percentage of patients. Symptoms include unexplained muscle pain, tenderness, and weakness. If your CPK is significantly elevated on statins, our doctor will advise on medication adjustment or switching.

What is rhabdomyolysis and how is CPK used to diagnose it?▼

Rhabdomyolysis is the breakdown of skeletal muscle, releasing large amounts of CPK and myoglobin into the bloodstream. It can be caused by extreme exercise, crush injury, heat stroke, or certain medications. CPK levels in rhabdomyolysis are typically 5–100 times above normal and require urgent assessment for kidney protection.
