Application study of hsCRP detection in different types of child infections / 国际检验医学杂志

ABSTRACT

Objective To investigate the expression level of hyper sensitivity C-reactive protein (hsCRP) in children infected with different pathogens in order to enhance the application value of hsCRP .Methods One hundred and one children patients with infection from March 2010 to March 2015 were selected as the research subjects and divided into the bacterial infection group (67 ca-ses) and mycoplasma infection group (34 cases) according to the hematology and bacterial culture results .Contemporaneous 50 healthy children were selected as the control group .Venous blood was collected for detecting hsCRP ,white blood cell(WBC) and neutrophil percentage(NEUT% ) .Results The levels and abnormal rates of hsCRP and WBC in the bacterial infection group were significantly higher than the those in the mycoplasma infection group and control group (P<0 .05);NEUT% and abnormal rate in the mycoplasma infection group was higher than that in the other two groups (P<0 .05) .The levels and abnormal rates of hsCRP and WBC after treatment in the bacterial infection group were lower than those before treatment ,the difference was statistically sig-nificant(P<0 .05);the area under the ROC curve of hsCRP for diagnosing bacterial infection wa maximal ,which was 0 .68 ,the sensitivity and specificity were 89 .9% and 88 .3% respectively .Conclusion The hsCRP level detection has early diagnostic value for child bacterial infection and can dynamically reflects the curative effect .
