Clinical value of combined detection of PCT,CRP and WBC in diagnosis of neonatal infectious pneumonia / 国际检验医学杂志

ABSTRACT

Objective To explore the clinical value of combined detection of procalcitonin (PCT ) ,C reaction protein (CRP) and white blood cells (WBC) count in diagnosis of neonatal infectious pneumonia .Methods A total of 137 cases of neonatal infectious pneumonia ,including bacterial infection group of 72 cases and non‐bacterial infection group of 65 cases ,were selected .Another 63 healthy neonatus were enrolled as control group .Levels of PCT ,CRP and WBC were measured .Results Levels and positive rates of PCT ,CRP and WBC in bacterial infection group were significantly higher than the other two groups (P<0 .05) .The sensitivity and specificity of PCT were higher than CRP and WBC .The sensitivity of combined detection were further increased .Conclusion Diagnostic sensitivity and specificity of PCT could be higher than CRP and WBC .Combined detection of PCT ,CRP and WBC might be with important clinical value for the differential diagnosis of neonatal infectious pneumonia and observation of curative effect .
