A Reticulocyte Count measures the number of reticulocytes (immature red blood cells) in the bloodstream. Reticulocytes are produced in the bone marrow and mature into red blood cells. This test helps assess bone marrow function and the body’s ability to produce red blood cells. It is often used to monitor conditions like anemia, blood loss, or bone marrow disorders. An elevated reticulocyte count can indicate increased red blood cell production, often in response to anemia or blood loss, while a low count may suggest bone marrow dysfunction or certain types of anemia.
