Diagnostic value of procalcitonin combined with C-reactive protein and white blood cell in bacterial pneumonia
Objective This paper aims to investigate the diagnostic value of procalcitonin combined with C-reactive protein(CRP)and white blood cell(WBC)count in bacterial pneumonia.Methods A total of 294 patients with respiratory tract infection who were admitted from January 2020 to December 2022 were selected as the research objects.According to the pres-ence or absence of pathogenic bacteria in sputum culture,they were divided into bacterial group and non-bacterial group.Another 147 healthy people who underwent physical examination during the same period were selected as the control group.The indicators of PCT,CRP and WBC were compared among the three groups.Results The levels of PCT,WBC and CRP in bac-terial group were higher than those in non-bacterial group and control group,with the differences statistically significant(P＜0.05).The positive rate of three indexes in the bacterial group was higher than that in the non-bacterial group and the control group,and the differences were statistically significant(P＜0.05).Conclusion The combined detection of WBC,CRP and PCT can provide a new strategy for bacterial pathogenesis,which is worthy of clinical application.
