Study on the diagnosis of upper respiratory tract infections in children by blood routine and C-reactive protein
Objective To evaluate the efficacy and clinical value of blood routine combined with C-reactive protein(CRP)in the diagnosis of upper respiratory tract infections in children.Methods A total of 185 children with upper respiratory tract infections who came to Zaozhuang City Yicheng District People's Hospital for treatment from January to December 2022 were selected and divided into the mycoplasma group with 34 cases,the bacterial group with 64 cases and the viral group with 87 cases based on the different types of pathogens in the children.In addition,80 healthy children who came to this hospital for health examinations during the same period were selected as the control group for this study.The serum CRP and white blood cell count(WBC)of four groups were measured and compared.Results The serum CRP and WBC in the bacterial group were significantly higher than those in the mycoplasma group,viral group and control group,and the differences were statistically significant(P＜0.05).The serum CRP in the mycoplasma group and viral group were higher than those in the control group;the WBC in the viral group was lower than that in the control group and mycoplasma group,the WBC in the mycoplasma group was higher than that in the control group,and the differences were statistically significant(P＜0.05).The accuracy and sensitivity of WBC combined with CRP in diagnosing upper respiratory tract infections were higher than those of WBC and CRP,the specificity was lower than that of WBC and CRP,and the differences were statistically significant(P＜0.05).Conclusion WBC and CRP were beneficial for distinguishing the types of infectious pathogens,and combining them could improve the accuracy and sensitivity of diagnosing upper respiratory tract infections,which was worthy of clinical promotion and application.
