Laboratory Markers of Impaired Erythropoiesis in Early Diagnosis of Perioperative Anemias

The Ret-He and Delta-He values in patients with unchanged hemoglobin allow for making a decision on the need for ECC transfusion therapy in the postoperative period.The differences between the groups formed on the basis of Ret-He and Delta-He deviations from the reference values are in line with the diagnostic signs of anemias of various origins. They also allow one to discuss the variants of impaired erythropoiesis at the very early stages of the disorder and the risk of anemia development in patients with formally unchanged total hemoglobin levels.
