Hi, i am 67 yrs old, I weigh 125 lbs. i recently got the result of my bloodworks. The doctor said everything was okey, except that my sugar is a bit high. I do not have a history of Diabetes, though. I noticed in the result that indicated an H Grace in the level (S) Leuk., but in the reference range is Negative. The H Trace, though is in the column of Out of range . Kindly, what did it mean? Thanks.
