I live with mild anemia: elevated MCV, HGB and HCT slightly low. They are always that way. My PCP and my Hemo aren't worried, so I'm not worried. Interestingly, in the year that I've been on Prep, the anemia has disappeared. Time will tell whether or not that change is permanent. I don't believe that Prep has cured my anemia, but it also appears that Prep doesn't cause anemia, at least not in me.
