Traceability and measurement uncertainty
A short introduction to the concepts of metrological traceability and measurement uncertainty is given in the article for readers who are not familiar with them. It also includes a short description of the steps needed to evaluate uncertainty. The article further explains how traceability is assured for the Sysmex haematology calibrators and describes how the uncertainty of these calibrators was evaluated.
Usefulness of neut-x determination in routine diagnostic procedures: application to myelodysplastic syndromes
Myelodysplastic syndromes (MDS) often go unnoticed when only a complete blood count is performed on the patient. Sysmex X-Class analysers can measure the granularity of leukocytes which is often reduced in MDS. NEUT-X, the measure of neutrophil granularity, is an excellent tool to filter samples suspected of MDS in anaemic patients.
Vyšetření počtu buněk v tělních tekutinách – provedení a interpretace výsledků
This SEED article is meant to explain the findings focused on cell count and differentiation for pleural, ascitic, cerebrospinal and synovial fluid as well as for CAPD. Traditionally, body fluid counts are performed by manual counting under a microscope using a haemocytometer, but laboratories now have the option of automating their manual processes using automated haematology or urinalysis analysers. This SEED summarises the advantages and disadvantages of haemocytometry and Sysmex analysers and explains briefly the XN-BF mode.
