background: automatic cell counter devises make the cbc differential very easy and delivering the results in few second. however, the problem with this device is facing a flag requires a time-consuming microscopic review of the specimen which causes unacceptable wait times for patient as well as costs for laboratories. in this study, we calculated the validity of wbc diff flags in sysmex xt-180...

Nucleated red blood cells (NRBC) in blood samples interfere with the white blood cell (WBC) count on many types of automated haematology analysers. This makes it necessary to correct the WBC count by counting NRBC microscopically. This report describes the evaluation of two analysers, the Cell-Dyn 4000 and the Sysmex XE-2100, which use new techniques to recognize and enumerate NRBC. We conclude...

In the present study we investigated the potential of the Sysmex XE-2100 automated hematology analyzer as a screening device for bone marrow (BM) aspirates. We evaluated BM cellularity, white blood cell (WBC) differential count, immature granulocyte (IG) count, nucleated red blood cell (NRBC) count, granulocyte/erythroid (G/E) and myeloid/erythroid (M/E) ratio, and potential pathologyrelated sc...

The XE 2100 (Sysmex Corporation) is a cell counter that furthers the technology of fluorescent flow cytometry developed from the earlier range of Sysmex analysers. The new diagnostic features are a nucleated red cell count (NRBC), the ability to measure platelets by impedance as well as an 'optical' platelet count using a fluorescence dye and an immature granulocyte (IG) count. The NRBC count w...

Introduction. The amount of immature leukocytes reflects marrow response to bacterial infection, and this may be quantified as the band or immature granulocyte (IG) count. The aim of this study was to analyze the IG count performance of the Sysmex XN-9000 hematology analyzer in intensive care unit (ICU) patients. Methods. 480 peripheral blood samples from adult patients admitted to the ICU (301...

INTRODUCTION In Ethiopia, CD4+ T-cell counting is still required for all patients at baseline before antiretroviral therapy (ART) and to determine eligibility and follow-up of opportunistic infection prophylaxis. However, access to CD4+ T cell count in rural health facilities remains a major challenge in Ethiopia like other resource-limited settings. METHODOLOGY Both capillary and venous bloo...

The XE-2100 is a new automated hematology analyzer developed by Sysmex Corporation. With consideration of medical analyzer requirements for the 21st century, this unit was developed to satisfy the following concepts and to cope with diversified laboratory needs. 1) Electronic network communication 2) Presentation of high level value-added information 3) Contribution to test cost control 4) Purs...

Since 1997, the availability, in haematology laboratories of automated analyzers capable of performing an extended differential blood cell count, including the nucleated red blood cell (NRBC) count, allowed their experimental use to estimate the cell composition of bone marrow fluid. In 1999 we evaluated the Sysmex XE-2100 to detect the clinical usefulness of immature granulocyte (IG) and NRBC ...

Reliable automated blood cell characterization and quantification remain challenging in pathologic samples, whereas slide reviews due to unnecessary flagging should be avoided. We compared 4 modern hematology analyzers-Abbott Sapphire, Siemens Advia 120, Sysmex XE-2100, and Beckman Coulter DxH 800-regarding complete blood cell count (CBC), leukocyte differential count, and flagging efficacy in ...

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...
