Comparison of the BD CytoRich^TM system with conventional methods of urine cytology

Abstract

In this study, we compared the cell yield produced by the BD CytoRich™ (CR) system with that obtained by conventional methods of urine cytology. A total of 100 urine samples were processed using both the CR system and conventional methods (Bales’ method). We assessed the epithelial cell counts and cellular distribution in slides obtained by both methodologies. Urine protein and blood levels were analyzed using a dip stick and compared with the epithelial cell counts from the slides processed using the CR system and conventional method. Overall, the slides processed using the CR system showed higher epithelial cell counts than those processed using the conventional method. Similarly, in cases of proteinuria and/or hematuria, the CR system demonstrated higher epithelial cell counts than the conventional method. Taken together, we conclude that the BD CR system is superior to conventional method of urine specimen preparation.
