Why would someone trigger for anisocytosis 3+ after 3 months of IV be venofer to treat an iron deficient microcytic anemia. Why would the RDW, MCH, and MCHC continue to trend in wrong direction with borderline 79-80 MCV, elevated reticulocyte, and anisocytosis 3+ when iron profile back on track and Hgb 12.7 (female)? RDW up to 22 now.
