【Abstract】 Objective To evaluate the main performance of BS 300 automatic biochemistry analyzer made in a Shenzhen Mindray Co. Methods To evaluate the precision, linearity crossing contamination and contrasting test of BS 300 automatic biochemistry analyzer by 9 items that contain all wavelength (ALT, GGT, Glu, TP, Alb, Cr, Ca, Cl -, ApoB). It was estimated its bias at medicine determined level concentration. Results The daytime run CV , within run CV , between run CV and total CV were under 4%. The diluted variance of linearity P was less than P 0.05 (0.684 1). The linear drift G was less than F 0.05 (3.29). The cross contamination rate was 2.81E 06, and correlated factor r with AU2700 was greater than 0.96. The relative biases at determined medicine level concentration with ALT,GGT,Glu,TP,Alb,Cr,Ca,Cl -(90 mmol/L), Cl -(120 mmol/L),ApoB were -1.8%,-0.1%, -3.9% ,-0.5%,-2.3%,-7.2%,0.4%,3.9%,3.2%,-1.7%. Conclusions The main performance of BS 300 automatic biochemistry analyzer accords with NCCLS, and is comparable to imported instrument. It is appropriate for small or middle sized hospital.更多还原
