Has anyone had a high CPK S result in bloodwork?

i just got my bloodwork back and am very happy with a1c (6!!) and triglycerides (35!!). yay for low carbing and honeymooning. i am about seven months type 1.
looking thru my tests, i saw this very high number for CPK S. the normal is between 10 and 195 and mine is 986!! i lked on the internet, (GP has no clue and i see my endo in sept) and its usually enzymes from damage to heart or muscles. nothing wrong there for me. has anyone else been tested for this and what does it mean? D related?
