Clinical significance: |
Useful in determining if the bone marrow is responding adequately to the body's need for red blood cells and to help determine the cause of and classify different types of anemia. The reticulocyte count is helpful in the evaluation of the bone marrow's ability to produce red blood cells (RBCs) and to help distinguish between anemia related to blood loss/destruction and anemia related to decreased RBC production. Also monitors bone marrow response and return of normal marrow following chemotherapy, bone marrow transplant or post treatment follow-up for iron deficiency anemia. RetHe gives a direct measurement ofthe functional iron available for RBC hemoglobinization. | ||||||||||||||||||||
