My original(now former) doctor never mentioned the high RBC. I came across it when looking at the results. I noticed that the RBC was nowhere near the normal range, but since my doctor never mentioned it, I never gave it a second thought. After getting the next blood test, and that too was showing a high RBC, I immediately knew it wasn't a one time fluke.
My neuro did tell me it could have been a number of different things, like dehydration and what not. What he didn't know is whether dehydration could cause the numbers to be THAT high.
Let me try and get my RBC numbers and let you see how out of whack they are.
