Objective To evaluate the precision of serum glucose (Glu) and blood urea nitrogen (Bun) measured by Johnson vitros 950 automatic dry-biochemical analyzer. Methods Two cases of hu-man pooled serum with medical decision levels were taken as experimental specimens. Detection was done twice a day on each speciment for 20 days. The experimental data were recorded carefully, and then the within-run imprecision, between-run imprecision, between-day imprecision and total impre-cision were calculated and compared with 1/4 CLIA'88 and 1/3 CLIA'88. Results The within-run im-precision, between-run imprecision of Glu and Bun in two levels were lower than 1/4 CLIA'88, while the between-day imprecision and total imprecision were lower than 1/3 CLIA' 88. Conclusion The Johnson vitros 950 automatic dry-biochemical analyzer possesses fine precision in Glu and Bun determi-nation,and can meet the clinical requirements.
