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.
