Reference intervals for reticulocyte count and derived reticulocyte parameters in a cohort of healthy adults.

Introduction: Reticulocyte count and novel derived parameters provide insight into the effectiveness of erythropoiesis and may be useful tools in the classification and diagnosis of anemias. However, there is no standardisation, so we consider it necessary that each laboratory evaluates the parameters according to its own methodology and instrumentation and establishes its own reference ranges. Our aim was to establish the reference intervals (RIs) of reticulocyte profile provided by the Beckman Coulter DxH 900 haematological autoanalyzer in our reference population.

Monocyte distribution width (MDW): study of reference values in blood donors.

Objectives: Monocyte distribution width (MDW) is a new biomarker used as an early indicator of sepsis (ESId). It is often aids in the identification of patients who may develop sepsis. This study aims to establish the MDW reference interval (RI) within the healthy population of blood donors using EDTA-K as anticoagulant.
