Does anyone know if someone suffering from a nutritional deficiency anemia would still show reticulocytosis?

I'm sure it's possible, but for the Step I, I would definitely think Reticulocytosis = Hemolysis. To quote from "Up to Date:"

Anemia with a low reticulocyte count is strong evidence for deficient production of RBCs (ie, a reduced marrow response to the anemia).

 

[Idiopathic]

For step 1, reticulocytosis is nearly pathognomonic for destruction of RBC's.
