Abstract
BACKGROUND. Urinalysis yields a great deal of information quickly and economically for detection of renal diseases. The inter-technician variation and time consuming are major problems while processing large amount of specimens. The purpose of this study is to evaluate the benefit of an automated urine analyzer, Yellow IRIS/model 450, and the feasibility of replacing the currently-used manual KOVA method. METHODS. A total of 1,000 random urine specimens were analyzed with Yellow IRIS and KOVA method. Precision, correlation, and detection rate of abnormality were compared between these two methods. RESULTS. The results revealed that Yellow IRIS had high precision with little between-run and within-run variation, while the obtained values were notably highly correlated with the expected values (r = 0.99). In addition, detection rate of blood cell abnormalities for the Yellow IRIS was twice better than for the manual KOVA method. CONCLUSIONS. The high precision of the machine, the simple procedure of performing, and the quickness of obtaining data, can minimize variability caused by the manual method and save processing time for mass screening. It is feasible to replace the manual urinalysis by the automated urine analyzer Yellow IRIS. Nevertheless, to minimize the extent of manual manipulation, including pouring the urine into the pour cup, and placement of the urine strip, will assist in a wider acceptance for the Yellow IRIS/Model 450.
