“…From a study by Sanchez-Mora et al, UX-2000 had a weighted kappa of 0.573 and 0.819 for categorical analysis of RBCs and WBCs, respectively. The weighted kappa for WBCs in that study was similar to our data (κ=0.803); however, we found greater agreement for RBCs (κ=0.721) 26. As for concordance rate within one grade difference, our results were higher than those from a study of theUF-1000i by Lee, et al-especially for RBCs and ECs (RBCs, 96.1% vs 83.7%; WBCs 96.8% vs 93.8%; ECs 96.6% vs 81.3%…”

“…Many studies showed the benefit of urine analyzers which are convenience, time‐saving, accurate, and standardization . To our knowledge, there is limited literature published on effectiveness analysis of automated urine analyzers as well as autoverification of urinalysis over the course of years.…”

AbstractBackground: In 2014, and implemented a new process that uses fully automated instrumentation, the lean management approach, and autoverification to improve the productivity and efficiency of the urinalysis workflow process. The aim of this study was to evaluate analytical turnaround time compared with our old urinalysis workflow process and our new urinalysis workflow process that was launched in 2014. Methods:This study was performed at the Central Laboratory of our center during June 2017 using data collected from the July 2012 (old process) and July 2014 (new process) study periods. We used our laboratory information system to compute and analyze turnaround time of urinalysis tests, and those results were compared between processes. Results:The 90th percentile turnaround time in overall data was dramatically decreased from approximately 60 minutes in 2012 to <50 minutes in 2014. The mean during both 6:pm was approximately 42 minutes in 2012; however, that duration was reduced to approximately 30 minutes for both of those time periods in 2014. Specimens within 60 minutes in both intervals increase from approximately 80% to more than 90%. Conclusion:The results of this study revealed our new urinalysis workflow process that incorporates fully automated instrumentation, the lean management approach, and autoverification to be effective for significantly increasing productivity as measured by analytical turnaround time and removing 1 staff to another section.

“…The most popular approach is to combine test strips with UFCs for primary screening either using both methods (i.e., UFC and strips) or by utilizing the test strips for analytes unrelated to the UFC-analyzed particles. As mechanical coupling of UFCs and test strip readers has been realized [40], expert systems now exist combining both test modalities based on user-definable decision rules. The implementation of such a strategy significantly reduces microscopy review and saves time and cost without diminishing clinical utility.…”

New technological advances have paved the way for significant progress in automated urinalysis. Quantitative reading of urinary test strips using reflectometry has become possible, while complementary metal oxide semiconductor (CMOS) technology has enhanced analytical sensitivity and shown promise in microalbuminuria testing. Microscopy-based urine particle analysis has greatly progressed over the past decades, enabling high throughput in clinical laboratories. Urinary flow cytometry is an alternative for automated microscopy, and more thorough analysis of flow cytometric data has enabled rapid differentiation of urinary microorganisms. Integration of dilution parameters (e.g., creatinine, specific gravity, and conductivity) in urine test strip readers and urine particle flow cytometers enables correction for urinary dilution, which improves result interpretation. Automated urinalysis can be used for urinary tract screening and for diagnosing and monitoring a broad variety of nephrological and urological conditions; newer applications show promising results for early detection of urothelial cancer. Concomitantly, the introduction of matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF MS) has enabled fast identification of urinary pathogens. Automation and workflow simplification have led to mechanical integration of test strip readers and particle analysis in urinalysis. As the information obtained by urinalysis is complex, the introduction of expert systems may further reduce analytical errors and improve the quality of sediment and test strip analysis. With the introduction of laboratory-on-a-chip approaches and the use of microfluidics, new affordable applications for quantitative urinalysis and readout on cell phones may become available. In this review, we present the main recent developments in automated urinalysis and future perspectives.
