Reticulocytes are young, immature red blood cells that have just been released from the bone marrow. A reticulocyte count reveals how quickly the bone marrow is producing new red blood cells. In anemia, this test helps determine whether the bone marrow is responding appropriately (high reticulocytes = the marrow is trying to compensate, as in blood loss or hemolytic anemia) or failing to produce enough cells (low reticulocytes = bone marrow problem, nutritional deficiency, or chronic disease). It is also used to monitor recovery after chemotherapy, bone marrow transplant, or treatment for nutritional anemia.
Blood health testing evaluates your blood cells, clotting factors, and oxygen-carrying capacity to detect anemia, infection, bleeding disorders, and other hematologic conditions.
Anyone investigating unexplained fatigue, frequent infections, bruising, or as part of a routine health check.
