WebOct 30, 2024 · Erythropoiesis is a tightly regulated process in which the hemoglobin level is maintained in a narrow window between 135g/L and 155g/L under normal conditions or in response to stress such as chemotherapy. A complex lineage-specific transcription factor network underlies the homeostatic hematopoiesis and erythropoiesis mechanisms. WebConclusion: Due to their short lifespan reticulocytes and derived parameters reflect current erythropoiesis status, before Hb and erythrocyte indices drop. MCHr had the best AUC and diagnostic value compared to erythrocyte indices. MCHr is a reliable test for the investigation of ID and could improve the detection of iron deficient adults. blacknight cyber security international
