<prompt> Reticulocytosis is seen in all except:P.N.HHemolysisNutritional anemiaDyserythropoietic syndrome  <response>: Answer is both C and D Nutritional Anemia and Congenital dyserythropoeitic anemia Nutritional anemia is associated with normalLow 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.

Congenital Dyserythropoetic AnemiaCDAs Essential Hematology by Moss 097 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.
