A Comparative study on the performances of 77 Elektronika Urised 2-LabUmat 2 and Dirui FUS 200-H 800 urine analyzers

Abstract

A comparative study on the performances of 77 elektronika urised 2-LabUmat2 and Dirui FUS200 -H800 urine analyzersObjectives: This study aims to compare the analytical performance of the 77Elektronika brand LabUmat2-Urised2 model integrated urine analyzer and Dirui brand FUS200-H800 model integrated urine analyzer. Methods: Urine samples of 139 patients randomly selected from male and female patients of all age groups who were admitted to Ufuk University Faculty of Medicine, Dr. Ridvan Ege Hospital between 24.02.2020-28.02.2020 were analyzed on both devices. Results: The results of the samples whose WBC (white blood cell), RBC (red blood cell) and Squamous epithelial were measured using two different methods in microscopic analyzers were perfectly compatible in the same range and with three parameters (Gamma values 0.916; 0.770; 0.961, respectively). For the samples where crystal and cylinder tests were carried out in microscopic analyzers, Cappa values were 0.486 and 0.495, respectively. As the result of Passing-Bablok Regression analysis used for the method comparison of microscopic analyzers, Cusum test results were p<0.01, p=0.01 and p=0.65, respectively for the linearity in the measurement of WBC, RBC and Squamous epithelial. According to the Bland-Altman Compatibility Chart prepared to determine the difference between methods, the difference between the results of the measurements of WBC, RBC and Squamous epithelial in both devices were -29.3±1.

LX-8000R and UriSed 2 fully automated urine analyzers comparison to manual microscopic examination

“…In the same study, epithelial cell count demonstrated consistency by 86.6% between UF-1000i and iQ200, 85.1% between UF-1000i and UriSed, 87.6% between iQ200 and UriSed, and 90.2% between UF-1000i and iQ200 [16] . In a study, Ercin [18] compared Urised2 and FUS200 microscopic analyzers and found WBC, RBC and EPI cell counts to be within the same range and reported excellent consistency for these three parameters (Gamma value is 0.916, 0.770 and 0.961, respectively; p <0.001). Jintasuthanont et al [10] compared the results of UriSed analyzer with that of manual microscopy; they found the gamma value to be 0.837 for WBC, 0.918 for RBC, and 0.939 for squamous epithelial cell count, and they detected high correlation between the results obtained by full-automated analyzer and the results obtained by manual microscopy.…”

“…Ercin [18] reported high correlation between Urised2-LabUmat2 and FUS200-H800 devices for WBC count, but moderate correlation for RBC count. Moreover, according to the Passing-Bablok regression analysis in this study, they reported that there is no consistency between these two methods because of the presence of remarkable deviation from linearity for WBC and RBC counts (p <0.05 and p=0.01, respectively) but that they are concordance for EPI cell count (p=0.65).…”

In addition, Bland-Altman agreement plot graphics demonstrated that automated microscopy units of the two devices showed acceptable performance for WBC (-29.3 ± 1.96 SD), RBC (43.3 ± 1.96 SD) and EPI (-4.0 ± 1.96 SD) cell counts (18). Yalçınkaya et al (3) compared FUS200 and Urised3 urine analyzers where Deming regression analysis yielded a correlation coefficient of 0.961 and 0.961 for WBC and RBC counts, respectively.…”
