I also get IVIG every 3 weeks and from 1/2014 through 11/2014 was having many out of range results and chronic anemia although none were low WBC. In July after 6 months of being told by several doctors they didnt know why I was anemic, I took initiative to schedule myself with hematologist and although we havent figured out why it appears I am chronically losing iron (I have an Iron leak!) but with regular iron infusions I am now no longer anemic and am finally starting to getting some relief from the symptoms of sever anemia. I guess my point is perhaps establishing a relationship with a hematologist might help?
