Objective In this study, the quality performance of the FUS-200 automated urine sediment analyzer was evaluated, and its performance was proved to meet the clinical requirements and the ISO 15189 standard. Methods We evaluated the performance of FUS-200 automated urine sediment analyzer by precision, linearity, carryover contamination rate, stability, the negative coincidence rate and other indicators according to published standard. Results The results of precision, linearity, carryover contamination rate were all in the allowable range. Conclusion Performance verification of laboratory instruments must be performed regularly to ensure the accuracy of the test results.
