<prompt> True about iron deficiency anemia isare -Howel jolly bodiesAnisocytosisPolychromasiaAll  <response>: Ans. is b i.e., Anisocytosis Anisocytosis, hypochromia and poikilocytosis are seen in iron deficiency anemia. o MCV normal -- 82 to 96 IL is decreased in iron deficiency anemia 60-90 fL o Howell-Jolly bodies are seen in megaloblastic anema, after splenectomy and in hemolytic anemia not in iron deficiency anemia I think option c requires specific mention here: Polychromasia o Polychromasia refers to variation in erythrocyte coloration. o Normally younger immature erythrocytes stain blue with Romanowsky stain, whereas mature erythrocytes stain uniformly orange-pink. o A slight degree of polychromasia is normal i.e. some degree of variation in colour may occur normally. o When immature erythrocytes are released into circulation from bone marrow there is significant variation in color of erythrocytes -- Polychromasia. So, variation in color polychromasia largely relates to the maturation of cells. o Polychromasia is seen when erythrocytes are released prematurely e.g. in response to erothropoietin or architectural damage to bone marrow fibrosis, infiltration of bone marrow by malignant cells etc.
