New erythrocyte and reticulocyte parameters on CELL‐DYN Sapphire: analytical and preanalytical aspects

Abstract

The new RBC parameters of CELL-DYN Sapphire generally correlated well with those of Advia 120, although significant systematic differences were present, particularly in reticulocyte MCH and MCV. These differences necessitate instrument-specific reference ranges and clinical decision values. To minimize preanalytical effects, these parameters should be measured in fresh blood samples.
