Currently on Ferozinc. Hb has been 8–10 for years despite multiple iron supplements. Symptoms: constant dizziness, fatigue, severe hair fall.
Questions:
1. Does this CBC pattern (low MCV/MCH + high-normal RBC) warrant HPLC to rule out thalassemia trait?
2. Is IV iron indicated given ferritin 4 and non-response to oral iron?
