Performance Evaluation of a New Generation of Automated Analyzer for Pleural and Peritoneal Fluids Cytology.

Background: Hematologic counters with dedicated body fluids mode allows these samples to be analyzed in an automated manner. Our aim was to evaluate the performance of the Sysmex XN-3000 and compare it with the Sysmex XE-5000, in use in our laboratory for cytological analysis of body fluids.

Methods: We studied 108 pleural and peritoneal fluids.

UriSed as an Alternative to Phase-Contrast Microscopy in the Differentiation between Glomerular and Non-Glomerular Hematuria.

Background: Differentiation between glomerular and non-glomerular hematuria by observation of the erythrocyte morphology using phase-contrast is a time-consuming and labor-intensive procedure that requires skilled personnel. This paper has the purpose to evaluate the performance of UriSed (also called sediMAX in some countries) as an alternative to the phase-contrast microscopic analysis of erythrocyte morphology.

Methods: 312 urine samples with hematuria were analyzed by UriSed and by phase-contrast microscopy.

Urinalysis: comparison between microscopic analysis and a new automated microscopy image-based urine sediment instrument.

Background: Urinalysis is a high demand procedure, with a large amount of manual labor and poorly standardized. Recently a new walk-away automated urine analyzer has been introduced. The aim of this study was to evaluate the performance of UriSed as an alternative to the microscopic analysis of urine samples.

Electrophoretic pattern of concentrated urine: comparison between 24-hour collection and random samples.

The electrophoretic pattern of concentrated urine samples can be used to identify the type of proteins leaking into the urine and has diagnostic and prognostic value, providing information about the location (glomerular or tubular) and degree of renal injury. This test usually requires a 24-hour urine collection, which can be inconvenient because of its heavy dependence on patient compliance and frequently is unreliable because of errors in collecting a complete 24-hour urine sample. In this study, we compared the electrophoretic pattern in 24-hour urine collections and random samples among patients with glomerular diseases and a wide range of proteinuria.
