A comparison between China-made Mindray BS-2000M biochemical analyzer and Roche cobas702 automatic biochemical analyzer
Frontiers in Laboratory Medicine(2017)
摘要
Abstract Objective To assess the China-made equipment Mindray BS-2000M biochemical analyzer and explore the comparability between the results of the sixteen test parameters detected by Mindray BS-2000M biochemical analyzer and by imported equipment Roche cobas702 automatic biochemical analyzer. Methods In line with the American Clinical Laboratory Standardization Committee (NCCLS) document EP9-A2, Switzerland Roche cobas702 biochemical analyzer was used as a comparison system, while the Mindray BS-2000M served as an experimental system. Sixteen biochemical parameters from forty cases at different levels were tested at the same time. The correlation coefficient(r), linearity regression equation and absolute deviation (SE) and relative deviation (SE%) of test detection system (Y) and control detection system (X) at different medical decision levels were calculated. The clinical acceptability and comparability between different detection systems were tested according to the standard of allowed total error of American Clinical Proficiency Testing Laboratory Improvement Amendments (CLIAu002788). Results The test results of the sixteen parameters between the two different biological detection systems were well-correlated ( r 2 ≥0.95, p Conclusion Mindray BS-2000M has achieved the desirable photometry technical and analytical performance, and can therefore be used in modern clinical laboratories.
