Abstract:Objective To explore the applicability of Mindray’s LabXpert System in automatic checking of routine blood tests.Methods Between June and July 2017, Mindray’s LabXpert (the Expert System) software was used to analyze the data on blood routine tests, involving counting the overall proportion of automatic check, analyzing the composition of samples which violated the re-examination rules,randomly analyzing the mean and median turnover time (TAT) of 800 blood samples by comparing the automatic check with the traditional check method, and by counting the samples whose TAT was over 30-min.Results A total of 10,860 blood samples were collected and the pass rate of automatic check reached 84.2%.The composition of samples that violated the re-inspection rules was analyzed.The main types of samples that violated the re-inspection rules were immature granulocyte warning and the number of immature granulocytes, WBCs which were beyond the normal range (WBC<4.0×109/L or>30×109/L) and reactive lymphocyte warning and other related rules.The average TAT of the automatic method was 20 minutes, while the percentage of TAT over 30 minutes was 20.63%.The average TAT of the traditional method was 26 minutes, and the proportion of TAT over 30 minutes was 30.25%, so the difference was statistically significant (P<0.05).Among the samples with overtime TAT , WBC-related parameters were the most abnormal(P<0.05), followed by RBC-related parameters and PLT-related parameters.Conclusions The Expert System software, when used to automatically check samples, can improve the work efficiency, shorten the time of TAT and guarantee the quality of reports.A laboratory can use this software to analyze the abnormal components and optimize the blood routine analysis process.
