A reticulocyte count indicated that 5% of a woman's RBC were reticulocytes. Is that normal for an adult?

Reticulocytosis. Whether a reticulocyte count is normal depends on how anemic the patient is. A high reticulocyte count usually indicates increased production of red cells by the bone marrow, but the reason for this can only be determined by a hematologist. Considerations include hemolysis (blood cell destruction), recovery from a vitamin deficiency, or recovery from bleeding. Please seek advice from your md.
