A member asked:

Reticulocyte count is .85% for a 70 years old man with macrocytic anemia. hb is 9 and mcv is 105. is the reticulocyte count normal?

A doctor has provided 1 answer

Probably not: In patients without anemia, a normal retic count is 1%. As anemia develops, if the marrow can respond, the retic count should rise, meaning more red blood cells are being made. Whatever is causing your anemia (with an elevated MCV), such as B12 deficiency or other causes, is also inhibiting your bone marrow from making new cells and thus your retic count is inappropriately low.
