Low Creatine kinase

I had a series of blood work done last week everything came back fine with one exception a low Creatine kinase. according to the lab normal range is 44 to 196

mine was a 30. Is this anything to be worried about? My muscles have felt weak for close to 2 years now

Ask your doctor if you're worried about the test result. But it seems to be one of those tests where they're worried if the result is high, not if it's low.

the doctor must not be too worried the test was last Tuesday and I got the results sent to me from the lab no call from the doctor so far. all the searches i did online tend to agree that they are only concerned if it to high
