Evaluation of a new rapid urine screening analyser: cellFacts

The aim of this study was to evaluate a new urine screening analyser in a H ospital Bacteriology Laboratory: the Celifacts Urine Screening Analyser (Mi crobial Systems Limited (MSL), Coventry, England). a cohort of 1036 urine s pecimens were analysed by both the CellFacts and routine traditional method s. Using the CDC urinary tract infection decision levels, and compared to r eference methods, the sensitivity and specificity were respectively 88.9% a nd 76.2%, and the predictive negative value and predictive positive value r espectively 93.3% and 64.8%. Compared to the microscopy, the correlations o f white blood cell count and red blood cell count were good, respectively ( 4 = 0.8, p < 0.0001) and (r = 0.6, p < 0.0001). These results indicate that , although several positive samples were not reported, CellFacts facilitate s efficient, rapid screening of infected urine specimens. This leads to per form a cytobacteriological analysis only on those results screened as posit ive by the automatic analysis system. (C) 2001 Editions scientifiques et me dicales Elsevier SAS.
