Auto-Identification of Discrepancies between Urine Test Strip and Sediment Results Using Cross Check Function on Fully Automated Urine Analyzer

Abstract

nbsp nbsp nbsp Background Urine chemistry test strip dipstick and microscopy examination are the basic procedure of urinalysis UX is the fully automated urine analyzer from Sysmex Corporation Japan which integrate urine test strip and urine particle assay on one platform This instrument is also equipped with crosscheck function which can correlate the test strip and urine particle results and the flag for discrepancies nbsp nbsp nbsp Aim The aim of this study was to evaluate the crosscheck function of UX and to assess its impact on laboratory efficiency nbsp nbsp nbsp Methods urine samples were collected and analyzed using UX Crosscheck results were obtained on combination parameters blood BLD amp red blood cell RBC leukocyte esterase LEU amp white blood cell WBC protein PRO amp cast CAST and nitrite NIT amp bacteria BACT Impact of crosscheck function on laboratory efficiency is determined using turn around time evaluation nbsp nbsp nbsp Results Crosscheck function results showed more than concordance between urine test strip and urine sediment and raise flag for discrepancies The application of this feature was able to reduce turnaround time from into minutes nbsp nbsp nbsp Conclusion The crosscheck function of UX enabled more efficiency to identify discrepant results and reduce turnaround time urinalysis examination nbsp
