Cpk-MM

You should get a CK-MM test if you have unexplained muscle pain, weakness, cramps, or swelling, or dark, cola-colored urine after an injury or intense exercise, which may signal rhabdomyolysis and needs urgent care. It is also recommended for suspected muscular dystrophy or myositis, and for those on statins with muscle symptoms.

No, fasting is not required for a CK-MM test. You can eat and drink normally before giving your sample. However, avoid strenuous exercise for 24–48 hours beforehand, as it can raise CK levels. Inform your doctor about any recent injuries, intramuscular injections, or statin use, as these may affect results.
