Application Effect of Automatic Blood Culture Instrument and Microbial Identification Instrument in Clinical Blood Test
Objective To study the application effect of automatic blood culture instrument and microbial identification instrument in clinical blood test.Methods A total of 80 patients who underwent blood test in our hospital from January 2021 to January 2023 were selected as the research objects.All blood samples were tested by automatic blood culture instrument and microbial identification instrument.The test time,test cost,detection rate of Gram-positive and Gram-negative bacteria between different test methods,and the test diagnostic efficiency of blood microorganisms(sensitivity,specificity,accuracy,positive predictive value,negative predictive value)were observed.Results The test time of automatic blood culture instrument was shorter than that of microbial identification instrument,and the test cost was lower than that of microbial identification instrument(P＜0.05).There was no significant difference in the detection rate of gram-positive bacteria and negative bacteria between the automatic blood culture instrument and the microbial identification instrument(P＞0.05).There was no significant difference in the sensitivity,specificity,accuracy,positive predictive value and negative predictive value between the automatic blood culture instrument and the microbial identification instrument(P＞0.05).Conclusion Automatic blood culture instrument and microbial identification instrument have high diagnostic efficiency in clinical blood test,but automatic blood culture instrument has short diagnosis time,low test cost and higher application efficiency.Clinically,more reasonable test methods can be selected according to the actual needs of the test to meet the clinical needs.
