CPK Isoenzymes Electrophoresis

A CPK isoenzymes electrophoresis test is advised when your total CPK is persistently high without a clear cause, to identify whether the damage is in the heart, skeletal muscle, or brain. It is also recommended when macro-CK is suspected, and for evaluating unexplained muscle weakness, suspected muscle disorders, or certain cancers.

No special preparation or fasting is required for a CPK isoenzymes electrophoresis test. Avoid strenuous exercise for 24–48 hours beforehand, as it can raise CPK levels. Inform your doctor about any recent injuries, intramuscular injections, surgery, heart problems, or medicines like statins, as these can affect results.

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