Study on the Relationship between dry Immunofluorescence quantitative Analysis of Procalcitonin and Blood Culture Results
Objective To analyze and discuss the relationship and value of dry immunofluorescence quantitative analysis in detecting blood culture and procalcitonin(PCT).Methods A total of 64 patients with bloodstream infection(BSI)from January 2021 to February 2023 were selected as the study subjects.PCT levels and blood cultures were tested,and the PCT levels of patients with negative and positive blood culture results were compared.At the same time,the distribution of pathogens in positive patients was analyzed,and the differences in PCT indicators among patients with different pathogen infections were compared.Results A total of 64 patients underwent blood culture tests,and 12 of them were positive,accounting for 18.75%,while 52 were negative,accounting for 81.25%;The PCT levels of patients with positive blood culture results were higher than those with negative results,and the difference was statistically significant(P<0.05).Among the 12 patients with positive blood culture,Gram negative bacteria accounted for the highest proportion of pathogens,accounting for 50.00%(6/12),followed by Gram positive bacteria at 33.33%(4/12)and fungi at 16.67%(2/12);The difference in PCT levels among patients with different pathogens was statistically significant(P<0.05),and the PCT levels in patients with Gram negative bacteria were higher than those in patients with Gram positive bacteria and fungi,with a statistically significant difference(P<0.05).Conclusion PCT is of great significance for diagnosing blood flow,and it is fast,simple,and cannot accurately identify pathogens.It can be combined with blood culture,which compensates for the shortcomings of PCT and can be used as the most valuable detection method for diagnosing blood flow infections.
