Detection of serum procalcitonin in diagnose of pediatric infectious diseases

Objective To explore the value of serum procalcitonin in the diagnosis of pediatric infectious diseases.Methods According to the diagnosis of the disease,324 cases were divided into a viral infection group (group B),a bacterial infection group (group A),and a non-infectious diseases group (group C).Complete blood count was carried out,C-reactive protein concentration was determined by immune turbidimetry,and PCT concentrations were measured by immune chromatography in all the children after being admitted into hospital.Result The levels of PCT,CRP,and CBC and the positive rate of PCT were significantly higher in group A than in group B and group C,with statistical differences (P ＜ 0.05).The PCT positive detection rate was significantly higher than the CRP positive detection rate and the CBC positive detection rate in group A,with statistical differences (P ＜ 0.05).Conclusions In the diagnosis of infectious diseases in children,the serum procalcitonin is a specific index of bacterial infections,can accurately diagnose bacterial infection and help pin down the clinical treatment plan,and is helpful for the patients' early rehabilitation.
