My wife's serum Iron and Ferritin levels are 30 and 8 respectively. She has a normal RBC, Hgb, and Hct levels. All of her RBC indeces (MCV, MCH, and MCHC) are in the normal range. She was previousely diagnosed with malabsorption syndrome due to Ibuprophin overuse. Thrre years ago, she was anemic and received Iron infusion.
My question is regarding her recent blood test results. She has Iron fediciency but not reflected in her RBC markers. What does this mean?
