Reticulocyte, Absolute details
What Reticulocyte, Absolute shows
Reticulocytes are young red blood cells recently released from your bone marrow, which mature into full red cells within a day or two. This result is the absolute count, the number of reticulocytes per volume of blood, rather than the percentage of all red cells. It shows how actively your marrow is producing red cells and helps work out the cause of anemia. A higher count suggests the marrow is responding to blood loss, red cell breakdown or treatment of a deficiency. A lower count suggests reduced production, as with iron, vitamin B12 or folate deficiency, kidney disease or marrow problems. It is interpreted with hemoglobin and other red cell indices.
Tests that include Reticulocyte, Absolute
