Good Afternoon: I Am A Very Healthy 64-year-old Female. I

Good afternoon: I am a very healthy 64-year-old female. I am not taking any medications, eat healthy and exercise. I recently had some bloodwork done (as I do every year at the health department) and my LDH was 246 (the lab's range is 119-226). My AST, ALT, GGT, bilirubin, alkaline phosphatase, albumin, and protein were all normal as were all the other chemistries. Should I be alarmed about this elevation?
