Reticulocyte haemoglobin content: 2020 update

Abstract

The hemoglobin content of reticulocytes (Hb-ret) is an effective real-time hemoglobin synthesis status indicator that permits diagnosis and monitoring of iron deficiency and iron deficiency anemia in all age groups with or without underlying diseases, including beta thalassemia. Hb-ret is less invasive than bone iron examination, less expensive than iron biochemical tests and might be available even in local laboratories. This review covers reports published mainly in 2020 and some other studies dedicated to clinical application of Hb-ret measured by Sysmex hematology analyzers.
