Abstract:Objective To discuss the comparability of the detection results of blood glucose(Glu),blood uric acid(BUA) and cholesterol(CHOL) in different detection systems to ensure the accuracy of the same item when using different instruments and equipment in the laboratory and provide the basis for the consistency of the results.Methods Beckman AU5800 automatic biochemical analyzer detection system was served as the target detection for compartive method,and Xuanda (SD1311) and Yili (ET301) portable detection system were used for experimental method.The Glu,BUA and CHOL were respectively measured with different detection systems in 40 patients,and the relative bias (SE%) between experimental method and comparative method was calculated to judge the comparability and consistency of different detection systems.Results The biochemical analyzer showed good precision and reliable results.In Xuanda detector,SE% for Glu at levels of low,middle and high medical decision were 12.6%,15.4%,and 15.9%,respectively;SE% of BUA were 11.2％,7.9％ and 7.6％,respectively;SE% of CHOL were 5.9％,6.1％,6.5％,respectively.In Yili tester,SE% for Glu at levels of low,middle and high medical decision were 10.7%,9.4%,and 9.1%,respectively;SE% for BUA were 12.8%,6.4% and 5.9%,respectively;SE% for CHOL were 9.8%,8.8%,6.8%,respectively.All of above results were below the acceptable limit,indicating that the test results by two kinds of Portable detectors were consistent with those of biochemical instruments.Linear correlation analysis showed that when detecting abone three indicators,the correlation coefficients between any two of the three detection systems were greater than 0.975.Conclusion The results of Glu,BUA,and CHOL detected by Xuanda (SD1311) and Yili (ET301) are consistent and comparable with the results of the AU5800 biochemical analyzer.
