Iron deficiency
Thalassemia major
Thalassemia minor
Megaloblastic anemia
RBC count within normal limits 4.5(4.2-5.4 millions for female). Therefore rule out anemia MCV 55 => microcytic (80-96 fL ). Could be thalassemia minor or major Since it is a female aged 30 more probablity for thalassemia minor Ref : Robbins 9/e pg 414
