Reticulocytosis is seen in all except:

Answer is both C and D (Nutritional Anemia and Congenital dyserythropoeitic anemia) Nutritional anemia is associated with normal/Low Retriculocyte count. Increased reticulocyte count (Reticulocytosis) is not a feature ,,f nutritional anemias. Nutritional Anemia Anemia resulting from deficiency of impoant nutrients in diet is called Nutritional anemia. Nutritional anemia is most commonly seen secondary to deficiency of Iron (Iron deficiency anemia) and vitamin B12 and Folic acid (Megaloblastic anemia). Both iron deficiency anemia and megaloblastic anemia are associated with low reticulocyte count. Congenital Dyserythropoetic Anemia(CDA's) (Essential Hematology by Moss 0/97) Congenital dyserythropoetic anemias are a group of hereditary refractory anemias characterized by ineffective erythropoesis. The reticulocyte count in these disorders in characteristically low (to normal for the degree of anemia). Paroxysmal Nocturnal haemoglobinuria (PNH) Paroxysmal Nocturnal Haemoglobinuria is associated with Intravascular hemolysis and is a known cause for elevated Reticulocyte count.
