Abstract

<p>Fully automated urine sediment analyzers have been commonly used, and this contributes to the automation and optimization of urinalysis. Several types of instrument using digital image analysis or flow cytometry are available. We conducted a comparison study to evaluate the analytical performances of AUTION EYE AI-4510 (hereafter, AI-4510), Atellica UAS800 (hereafter, UAS800), and UF-5000. The focus of this study was on the availability of those devices for holiday/night medical services. We compared the repeatability, correlation, and interference by turbid urine among these three devices by using 561 clinical specimens. All the results of repeatability showed a within ±1 rank variation. We found differences in sensitivity and specificity among the three devices. Although the correlation, which was represented as a ±1 rank match, was almost comparable, UF-5000 showed better correlation with RBC, WBC, and BACT, which are especially important for holiday/night medical services. Regarding the required duration for the measurement of turbid urine specimens, UAS800 showed a constant term, whereas AI-4510 and UF-5000 did not. Since the urinary sedimentation test is a morphological test, there are differences among experiences and individual differences between day and night shift staff. To eliminate these concerns, a urine sediment analyzer is useful. Utilizing the analyzer by taking advantage of it will be helpful to eliminate staff anxiety.</p>
