An increased reticulocyte count represents increased RBC production and is a criterion for hemolysis but is not specific for hemolysis. In addition to hemolysis, increased reticulocytes may be a response to blood loss or the treatment of iron, vitamin B-12, or folate deficiencies. The reticulocyte count may be normal or low in patients with bone marrow suppression despite ongoing severe hemolysis (aplastic crisis).
