Abstract:
Objective To investigate the correlation between the results of HBsAg positive results among different detection systems,and provide reference for the analysis of clinical test results and the publication of the report.Methods The HBsAg positive serum specimens with the quantitation result lower than 80 COI were detected by Roche Cobas e602 electrochemical luminescence analyzer.All the specimens were also detected by Roche Modular e170 electrochemical luminescence analyzer.The differences of detecting results were compared and performed the linear correlation analysis.Results The experimental results of two detection systems are R2 =0.933.The positive coincidences of Group A,B,C,D and E were 60.60％,92.72％,96.66％,96.66％ and 100％,respectively.The positive coincidence of the males was 87.66％,while the positive coincidence of the females was 70.96 ％.The positive coincidence of the males was significantly higher than the females (P＜0.05).Conclusion The HBsAg detecting results of Roche Cobas e602 and Roche Modular e170 electrochemical luminescence analyzer had high correlation.The results higher than 10 COI had 100％ positive coincidence rate,however the results between 1 and 10 COI were not.The result between 1 and 10 COI may lead to controversial results,suggestions for further checks.
