It's hard to know: CK is an enzyme that is commonly found in different types of muscle cells. It can be found in skeletal muscle cells - think your biceps - but also your heart muscle cells. The CK-MB allows doctors to better determine if muscle damage is heart in origin -reassuring that was normal for you. You may naturally have high serum levels of CK or some minor damage to the some skeletal muscle(s).
