WebErythroblasts require large amounts of iron for hemoglobin synthesis. Large amounts of iron are recycled daily with hemoglobin breakdown from destroyed old erythrocytes. Many recently identified proteins are involved in absorption, storage, and cellular export of nonheme iron and in erythroblast uptake and utilization of iron. WebHemoglobin tests are part of a complete blood count (CBC) test, which identifies the number of red blood cells, white blood cells and platelets in a blood sample.
