RBCs5
- Normocytic anemias can be further classified as hemolytic when there's increased destruction of RBCs, or hemolysis , and non-hemolytic when there's decreased production of RBCs from the bone marrow. (osmosis.org)
- When there's hemolysis , the bone marrow revs up and starts pumping out immature RBCs called reticulocytes, but when there's a bone marrow problem reticulocyte count is low. (osmosis.org)
- The absolute reticulocyte count and corrected reticulocyte percentage, as a marker of RBC production, provide an initial evaluation as to whether anemia is due to loss of RBCs or inadequate production. (medscape.com)
- Numbers of circulating RBCs are affected by changes in plasma volume, rate of RBC destruction or loss, splenic contraction, erythropoietin (EPO) secretion, and the rate of bone marrow production. (ivis.org)

(medscape.com)
- therefore, it is not necessary to calculate a correction for absolute reticulocyte count. (medscape.com)
- [ 3 ] However, even when the degree of anemia is corrected for, another factor that can result in spuriously elevated reticulocyte percentage and absolute reticulocyte count is the time reticulocytes spend in the blood circulation prior to maturation. (medscape.com)
- however, in the setting of stress erythropoiesis, as in a high erythropoietin level (eg, in persons with severe anemia), reticulocytes are prematurely released from bone marrow to the blood circulation, increasing the number of days that reticulocytes stay in the blood circulation (maturation time of reticulocytes in days) and resulting in a spuriously high reticulocyte count. (medscape.com)
