Well, i'm at that point. My RBC count is over the reference range, and both hemoglobin and hematocrit are both right at the cusp. I've been advised to donate blood every few months, but I don't know how to proceed.

I remember a while back, somebody mentioned a post that explains the questions that will be asked and how to answer them so I have no issues. Can somebody please point me to it, or explain here? Much appreciated.
