Lack of harmonization in high fluorescent cell automated counts with body fluids mode in ascitic, pleural, synovial, and cerebrospinal fluids

Abstract: Introduction Cellular analysis in body fluids (BFs) provides important diagnostic information in various pathological settings. This study was hence aimed at comparing automated cell count obtained with Mindray BC‐6800 (BC‐BF) vs Sysmex XN‐series (XN‐BF) and evaluating other quantitative and qualitative information provided by these analyzers in ascitic (AF), pleural (PF), synovial (SF), and cerebrospinal (CSF) fluids. Methods Three hundred and fifty‐one samples (99 AFs, 45 PFs, 75 SFs, and 132 CSFs) were anal… Show more

“…The results obtained by comparing results obtained with XN-BF mode and OM show an acceptable agreement. The overall bias was −4.5% for the total cell count, similar to that already reported for ascitic, pleural and synovial fluids,35 and −3.2% for MN-BF% compared with MN3-OM% (ie, the sum of LY, MO, MA and ME) (table 3). Figure 2 shows a particular trend, highlighting that the bias seems proportional to the number of cells, while concordance is lower for all the other cell populations.…”

“…The Passing and Bablok regression analysis yielded slopes >1.5 or <0.7, with bias ranging from −47.7% for MN-BF compared with MN3-OM, up to 127.1% by comparing PMN-BF with PMN-OM. These results are somehow unexpected considering the good analytical performance and previous correlation studies performed on other biological fluids (ie, % bias always <21% and slopes generally comprised between 0.9 and 1.0) 35. This evident discrepancy can be attributed to some peculiarities of the PF, especially to the different types of cells that can be found in this biological material compared with ascitic and pleural fluids (table 2).…”

“…Sus principales ventajas son la disponibililidad de un material de control de calidad interno, el corto tiempo para el análisis (<3 minutos), el bajo volumen de muestra requerido (150 μL) y la posibilidad de procesar muestras sin pretratamiento previo. Estudios recientes han evaluado sus características analíticas (Tabla 1) y la transferibilidad de resultados respecto al método de referencia [25,[30][31][32][33][34][35], confirmando su utilidad en LCR [31] y en los líquidos pleural y ascítico [32]. Sin embargo, la evaluación cualitativa sistemática del escartegrama de diferenciación (DIFF) y del HF-BF* es esencial para la generación de algoritmos, como criterios para decidir la necesidad de la revisión microscópica [33].…”

Sin embargo, la evaluación cualitativa sistemática del escartegrama de diferenciación (DIFF) y del HF-BF* es esencial para la generación de algoritmos, como criterios para decidir la necesidad de la revisión microscópica [33]. En este sentido, Buoro et al [32,33] recomiendan la revisión en LCR con WBC-BF en el rango entre 4,0 y 7,0/μL, en presencia de un escatergrama DIFF anormal, que puede ser consecuencia de la presencia de microorganismos, con la consecuente repercusión diagnóstica [34], o por incrementos de la diferencia entre el TNC-BF y WBC-BF, que se traduce en el aumento del HF-BF* [31].…”
