Reference Range of Platelet Count in Normal Pregnancy using Sysmex SE-9500
نویسندگان
چکیده
We performed a study on 210 pregnant women to determine platelet reference ranges and to evaluate differences with a control group of 210 healthy non–pregnant women using the Sysmex SE-9500. During the second and third trimesters of pregnancy a decrease in platelet count (PLT) occurred but this was not statistically significant. However, during the same period statistically significant increases were noted in mean platelet volume (MPV), platelet large cell ratio (P-LCR) and platelet distribution width (PDW). It is important that haematologists and obstetricians are aware of these different reference ranges during pregnancy.

Reference intervals for a complete blood count determined on different automated haematology analysers: Abx Pentra 120 Retic, Coulter Gen-S, Sysmex SE 9500, Abbott Cell Dyn 4000 and Bayer Advia 120.
We processed 317 samples from healthy adult volunteers for a complete blood count, including leukocyte differentials and reticulocyte parameters, through five new-generation haematology analysers: Abx Pentra 120 Retic, Coulter Gen-S, Sysmex SE 9500, Abbott Cell Dyn 4000 and Bayer Advia 120. From these data non-parametric 2.5-97.5 percentile reference intervals were calculated for all parameters...
متن کاملPlatelet counting by the coulter LH 750, sysmex XE 2100, and advia 120: a comparative analysis using the RBC/platelet ratio reference method.
We compared the accuracy and precision of the impedance platelet counts generated by the Beckman Coulter LH 750 and the Sysmex XE 2100 and the optical platelet counts produced by the Advia 120 and the Sysmex XE 2100 withflow cytometric reference platelet counts. Samples analyzed had platelet counts less than 150 x 10(3)/microL (150 x 10(9)/L) with a platelet flag or less than 75 x 10(3)/microL ...
متن کاملReference interval for immature platelet fraction on Sysmex XN haematology analyser in adult population
Introduction The Sysmex XN-series haematology analyser has newly adopted a fluorescent channel to measure immature platelet fraction (IPF). To promote the clinical utility of this promising parameter, establishing a reliable reference interval is mandatory. According to previous studies, IPF values may be affected by the employed analyser and the ethnic background of the individual, but no diff...
متن کاملUse of the haemopoietic progenitor cell count of the Sysmex SE-9500 to refine apheresis timing of peripheral blood stem cells.
The Sysmex SE-9500 automated cell counter provides an estimate of immature cells referred to as 'haemopoietic progenitor cells' (HPC). The aim of this study was to relate the HPC count to CD34+ cell levels in mobilized peripheral blood and to determine whether the HPC count was valuable in predicting apheresis yields of CD34+ cells. Studies were performed on 114 samples from 67 patients undergo...
متن کاملThe Sysmex XN-2000 Hematology Autoanalyzer Provides a Highly Accurate Platelet Count than the Former Sysmex XE-2100 System Based on Comparison with the CD41/CD61 Immunoplatelet Reference Method of Flow Cytometry
Dear Editor The recently launched hematology autoanalyzer Sysmex XN2000 (Sysmex, Kobe, Japan) provides a new method (PLT-F method) for platelet counting based on a fluorescent RNA staining dye named oxazine [1, 2]. The main advantage of the XN2000’s PLT-F method over the former instrument XE-2100’s optical method (PLT-O method) is the ability to identify apoptotic white cells and not count them...
