The aim of this study was to evaluate the consistency and accuracy of all the parameters of the urine samples detected by two automated urine sediment analyzers from Sysmex Corporation.Two automated analyzers and manual microscopy examined 1,059 urine samples. The sensitivity, specificity, positive predictive value, and negative predictive value were evaluated. The consistency of all the parameters was tested. The influencing factors of false positive and false negative samples were analyzed and compared.All the parameters had good specificity, negative predictive value, and coincidence rate (83.95%-99.61%). The RBC, WBC, and X'TAL analyzed by UF-5000 and UF-1000i exhibited good agreement (Kappa=0.597-0.784) with those by manual microscopy. The overall concordance rates of RBC and WBC were good (RBC: r=0.9842, CCC=0.9693; WBC: r=0.9955, CCC=0.9711). Among the influencing factors, mucus filament accounted for a large proportion, which mainly affected the detection of CAST. Concurrently, the false-positive factors of EC detection were reduced, and CAST did not affect the detection of EC.The parameters of the two instruments tested have shown high accuracy, consistency, coincidence rate, and low negative predictive value for RBC and WBC, which has ensured that UF-5000 and UF-1000i meet the clinical requirements for urine tests for disease screening. For the samples with poor consistency and false-positive factors, a conventional microscopic examination should be applied to verify the accuracy of the instrument detection.
