Cerebrospinal Fluid (CSF)

Buoro S et al. (2018): Two-site evaluation of the diagnostic performance of the Sysmex XN Body Fluid (BF) module for cell count and differential in Cerebrospinal Fluid. Int J Lab Hematol; 40(1): 26
What we see as the essence: The XN-BF mode provides rapid and accurate counts from of cerebrospinal fluid samples in clinically relevant ranges. It was found to provide a good alternative to conventional microscopic analysis.

Fleming C et al. (2015): Liposomal interference on Sysmex XN-series body fluid mode. Clin Chem Lab Med.; 54(1):e19
What we see as the essence: "Liposomal particles from DepoCyt chemotherapy treatment may be misclassified as polymorphonuclear cells by the XN-BF mode (software version 18). The authors worked together with Sysmex to develop an alert, available from software version 20."

Li A et al. (2014): Automated white blood cell counts in cerebrospinal fluid using the body fluid mode on the platform Sysmex XE-5000. Scand J Clin Lab Invest.; 74(8):673.
What we see as the essence: “In the present study, we found that the open body fluid mode of the Sysmex XE-5000 was a favourable method for determination of WBC counts and for differentiation between MNCs and PMNs, compared to manual counting."

Zimmermann M et al. (2011)
Automated vs. manual cerebrospinal fluid cell counts: a work and cost analysis comparing the Sysmex
XE-5000 and the Fuchs-Rosenthal manual counting chamber. Int J Lab Hematol. 33: 629–37.
What we see as the essence: Using the XE-5000 for automated counting in CSF is trustworthy
especially for severely pathological cell counts, but also below. The study demonstrates specific
and significant savings in terms of time and money (about 6 times).

Zur B et al. (2011): Evaluation of 2 Hematology Analyzers in Body Fluid Mode versus Flow Cytometry Immunophenotyping of Mainly Neurosurgical Cerebrospinal Fluid Samples. Cen Eur Neurosurg 73: 93–8.
What we see as the essence: "Determination of CSF cells with the XE-5000 is presently the best automated method for counting leukocytes of blood-stained CSF."

Sandhaus LM et al. (2010): Automated cerebrospinal fluid cell counts using the Sysmex XE-5000: is it time for new reference ranges? Am J Clin Pathol 134: 734–738.
What we see as the essence: "The correlation between XE-5000 and Fuchs-Rosenthal chamber over the entire range of data was very good. Studies are needed to determine method-specific reference intervals for white blood cells in CSF."

Boer K et al. (2009): Evaluation of the XE-5000 for the automated analysis of blood cells in cerebrospinal fluid. Clin Biochem 42: 684–691.
What we see as the essence: "Most patients were classified correctly using the XE-5000 which is thus suitable for automated quantification of white blood cells in CSF in a defined diagnostic setting. This could significantly improve automation of CSF diagnostics."

Xu W et al. (2017): Evaluation of Sysmex XN-1000 hematology analyzer for cell count and screening of malignant cells of serous cavity effusion. Medicine (Baltimore);96(27):e7433
What we see as the essence: The analysis of serous fluid on the XN-BF mode showed good comparability with microscopy. High fluorescence cells (HF-BF) count correlated with the presence of malignant cells.

Bottini PV et al. (2014): Comparison between automated and microscopic analysis in body fluids cytology.Int J Lab Hematol.;37(2):e16.
What we see as the essence: "The authors describe a performance evaluation of the XE-5000 body fluid mode for peritoneal and serous fluids. A good correlation between the XE-5000 and microscopy was found as well as good precision and low carryover."

Labaere D et al. (2015): Detection of malignant cells in serous body fluids by counting high-fluorescent cells on the Sysmex XN-2000 hematology analyzer.Int J Lab Hematol 2015; Int J Lab Hematol 37(5):715.  
What we see as the essence: "Analysis of serous fluids on the XN-2000 showed that the absence of high fluorescence body fluid cells (HF-BF) could be used to exclude malignant samples: the negative predictive value was 92% at a cutoff of 2.1% and 95% at a cutoff of 17/µL."

Lippi G et al. (2013): Evaluation of the Fully Automated Hematological Analyzer Sysmex XE-5000 for Flow Cytometric Analysis of Peritoneal Fluid. J Lab Autom 2013;18(3):240.
What we see as the essence: "This evaluation of the XE-5000 for peritoneal fluid analysis showed excellent performance for all analysed parameters. The performance of the XE-5000 was slightly better than that of the XE-2100."

De Jonge R et al. (2006): Automated analysis of pleural fluid total and differential leukocyte counts with the Sysmex XE-2100. Clin Chem Med Lab 44: 1367–71.
What we see as the essence: "With some limitations, total and differential WBC counts in pleural fluid can be reliably determined using the XE-2100."

De Jonge R et al. (2004): Automated counting of white blood cells in synovial fluid. Rheumatol 43: 170–173.
What we see as the essence: "The WBC count in synovial fluid using the DIFF channel of the XE-2100 can be reliably determined more precisely and faster than by manual counting. The better precision may also improve the low confidence that clinicians have in these results at present."

General Body Fluids

Favresse J et al. (2018): Characterization of Candida spp. interference on the Sysmex XN-1000 body fluid mode. Int J Lab Hematol; 40(2): e28
What we see as the essence: The presence of yeast interferes with WBC and TC counts, and in a less extend with HF count when measuring body fluids on the XN-1000. “Therefore, the assessment of the typical “blue surfboard pattern” is also useful to identify the presence of yeast as it is important for laboratory specialists to report their presence” The absence of the flag “WBC abn Scattergram” does not proof that there are no interferences.

Cho YU et al. (2018): Validation of reflex testing rules and establishment of a new workflow for body fluid cell analysis using a Sysmex XN-550 automatic hematology analyzer. Int J Lab Hematol; 40(3): 258
What we see as the essence: The XN-550 was evaluated for body fluid analysis and the authors
conclude that the XN-550 is a suitable alternative to manual body fluid analysis. In addition, several
laboratory-specific cytospin review criteria were established, resulting in significant workflow

Seghezzi M et al. (2017) Preliminary evaluation of UF-5000 Body Fluid Mode for automated cerebrospinal fluid cell counting. Clin Chim Acta 473:133
What we see as the essence: The present study certifies a good agreement of the UF-5000 BF mode with manual chamber count for the parameters RBC, TNC, WBC (PMN/MN). The diagnostic performance was excellent especially in samples with few cells (RBC <1,000 cells/µL, WBC <20 cells/µL) as well as low LoB, LoD, LoQ and good linearity for CSF samples.

Fleming C et al. (2015): Clinical relevance and contemporary methods for counting blood cells in body fluids suspected of inflammatory disease. Clin Chem Lab Med 53(11):1689
What we see as the essence: Excellent review on body fluid analysis. Several different analysers
were compared, including the XE-5000, XN-Series and UF-Series.

Cho YU et al. (2015): Body fluid cellular analysis using the Sysmex XN-2000 automatic hematology analyzer: focusing on malignant samples. Int J Lab Hematol. 37(3): 346
What we see as the essence: It was found that cell counts obtained from the XN-2000 body fluid
mode were comparable to counts obtained from microscopy. The authors recommend that samples
with highly fluorescent cells (HF-BF) should be further analysed.

Fleming C et al. (2012): Validation of the body fluid module on the new Sysmex XN-1000 for counting blood cells in cerebrospinal fluid and other body fluids. Clin Chem Med Lab 50: 1791-1798.
Quote: "The BF module on the XN-1000 is a suitable tool for fast and accurate quantification of WBC
(differential) and RBC counts in CSF and other BFs in a diagnostic setting."

De Jonge R et al. (2010): Evaluation of the new body fluid mode on the Sysmex XE-5000 for counting leukocytes and erythrocytes in cerebrospinal fluid and other body fluids. Clin Chem Lab Med 48: 665–675.
What we see as the essence: The body fluid mode on the Sysmex XE-5000 offers rapid and accurate
RBC and WBC (differential) counts in clinically relevant concentration ranges in CSF and other fluids.

Paris A et al. (2010): Performance evaluation of the body fluid mode on the platform Sysmex XE-5000 series automated hematology analyzer. Int J Lab Hematol 32: 539–547.
What we see as the essence: The XE-5000 count is trustworthy and can provide more precise and
reliable information than the manual method using the Malassez chamber (1μL counting volume).

Riedl JA et al. (2010): Automated morphological analysis of cells in body fluids by the digital microscopy system DM96. J Clin Pathol 63: 538–43.
What we see as the essence: The 24 h available DM96 body fluid module reliably and accurately
preclassifies five main cell categories in cytospin slides with a low CV and an agreement of 90% as
compared with highly trained technicians, thereby contributing to quality improvement.
