全血C反应蛋白联合血常规检验在细菌感染性疾病诊断中的价值分析

Objective Discussion on the value of combining whole blood C-reactive protein with blood routine in the clinical diagnosis of bacterial infectious diseases. Methods The study included 126 patients suspected of bacterial infectious diseases from October 2022 to October 2024. All patients received whole blood C-reactive protein, blood routine test and bacterial culture. The results of bacterial culture were taken as the “gold standard”. This study evaluated the diagnostic efficacy indicators of single whole blood C-reactive protein test, single blood routine test, and combined test. According to the “gold standard”, patients were divided into the bacterial infection group and the non-bacterial infection group, and the single method for whole blood C-reactive protein detection and blood routine test and combined test of whole blood C-reactive protein with blood routine was compared. Results 78 cases of bacterial infectious diseases and 48 cases of non-bacterial infectious diseases were diagnosed by the “gold standard”. The sensitivity, specificity and accuracy of combined tests in the diagnosis of bacterial infectious diseases were higher than those of single whole blood C-reactive protein and single blood routine tests(P<0.05), joint inspection showed Kappa>0.8. Bacterial whole blood C-reactive protein and infection group were higher than those in the non-bacterial infection group(P<0.05). Conclusion The joint inspection of whole blood C-reactive protein and blood routine examination has a high diagnostic efficiency in the diagnosis of bacterial infectious diseases, which is helpful to improve the early diagnosis rate of bacterial infectious diseases.
