[The Diagnostic Value of Ret-He in Predicting Latent Iron Deficiency in Female Blood Donors].

Objective: To explore the application value of reticulocyte hemoglobin equivalent (Ret-He) for diagnosing latent iron deficiency in female plateletpheresis donors.

Methods: A total of 230 female plateletpheresis donors in Fujian Blood Center from January to February 2022 were selected as the research group and divided into three groups: normal group, iron depletion (ID) group and iron deficient erythropoiesis (IDE) group, according to the severity of iron deficiency. The level of hemoglobin (HGB), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), coefficient of variation of red cell distribution width (RDW-CV) and Ret-He were measured by using the Sysmex XN automated hematology analyzer.

[Relationship between Iron Metabolic Parameters and Platelet Counts in Blood Donors].

Objective: To investigate the correlation of iron metabolic parameters with platelet counts in blood donors.

Methods: A total of 400 blood donors who met requirements of apheresis platelet donation were collected, and their hematological parameters were analyzed. The donors were divided into low ferritin group and normal group, the differences of hematological parameters between the two groups were compared, and the correlation of iron metabolic parameters and routine hematology parameters with platelet counts were analyzed.
