Feasibility Analysis of Domestic Automatic Chemiluminescence Immuno-analyzer and Suggestions for Its Development
Objective To explore the feasibility of promoting domestic automatic chemiluminescence immunoanalyzer.Methods The venous blood samples of 40 patients from the First Affiliated Hospital of Guangxi University of Tradi-tional Chinese Medicine from July to October 2023 were selected as the research objects.Cardiac troponin I(cTnI)was detected by domestic Mindray CL-6000i automatic chemiluminescence immunoanalyzer and imported Abbott i2000SR automatic chemiluminescence immunoanalyzer.Coefficient of variation(CV)was used to calculate the preci-sion of the instrument,and the correlation regression equation was calculated according to the test data.Results The in-batch CV of the high and low levels of cTnI was less than 1/4 of the total error allowed(TEa)respectively.The inter-batch CV was also less than 1/3 tea respectively.In the linear range measured by cTnI,the correlation regres-sion analysis equation of the two detection systems was Y=0.9658X±0.1495,and the R2 was 0.983.Conclusion The cTnI detection results of the two detection systems have a good consistency,and the domestic Mindray automatic che-miluminescence immunoanalyzer can meet the clinical needs and is suitable for clinical laboratory use.
