Reticulocyte Count – Principle, Procedure, Calculations and Clinical Significances
What is Reticulocytes? Reticulocytes are immature red blood cells (erythrocytes) that have not yet completed the final stages of maturation. They are usually produced in the bone marrow and have a characteristic reticulated (network-like) appearance when stained with special dyes. Reticulocytes are important in the evaluation of anemia, as they provide information about the bone … Read more
