For the last 2-1/2 yrs my blood calcium rate has been a little elevated. It will range from 10.6 to 11.2, 10.5 being normal, and then back to normal range and back up again. I've had all the scary stuff eliminated, ie: bone scans etc. I feel fine and always have. All of the rest of blood work is always normal. Is it possible that someone could just have a slightly higher rate for no apparent reason.
