For the past few months, my iron bloodwork has been low and I'm having trouble understanding the results. In July, my bloodwork was normal, but my iron serum and transferrin saturation was low (iron serum was 30 and saturation was 8%). Hemataologist did 4 weeks of IV infusion (Ferracet?) and bloodwork is now worse. Iron serum is now 27, saturation is 8%, TIBC is normal and ferretin jumped from 35 to 135. However, hemoglobin dropped from 12.5 to 11.7. Hematocrit dropped from 37.5 to 34.5. RBC are now 3.9 and low MCV. What does this mean? I am a 45 yo female. Taking BC pills continuous so no bleeding and no other bleeding that I know of. Only symptom is tiredness.
