Creatine Kinase (CK or CPK)

Creatine Kinase (CPK/CK)

Blood levels of CK rise when muscle or heart cells are injured. Your doctor may test for CK if you have chest pain or other signs and symptoms of a heart attack. In the first 4 to 6 hours after a heart attack, the concentration of CK in blood begins to rise. It reaches its highest level in 18 to 24 hours and returns to normal within 2 to 3 days. The amount of CK in blood also rises when skeletal muscles are damaged.

Preparation: Avoid exercise prior to blood draw. Fasting is not required for this blood test. In general, being well hydrated (drinking plenty of water before the blood draw) will help make your veins somewhat easier to locate and access for the blood draw.

Estimated time to receive results is 1-2 days.
