Hi Bj87. Yes, this info is helpful. My HCT is in normal ranges. It's HGB is often low, RBC always low, RDW always high, and iron saturation % is typically quite low (4-6%), and Ferritin drops to 5 if not caught in time. I get iron infusions every 3 mos on average. I just found out that I have IgA deficiency and another immunoglobin is low, so referred to a immunologist. I had no idea about this issue, but now so many of my symptoms are making more sense. Guess I am feeling a bit hopeful now bc I may be a candidate for immunotherapy, which could contain my constant battle with infections, and other stuff. The fatigue is rough, which I'm sure for you too.
