ABSTRACT
Objective To investigate the diagnostic value of neutrophil CD64 expression for bacterial infection in children . Methods 168 children were divided into the infection group (n=133) and non-infection group(n=35) according to the results of bacterial culture .CD64 reagents from Beckman company and BD company were employed to detect CD 64 in neutrophils and lym-phocytes .Flow cytometry was used to assay their average fluorescence intensity and the CD 64 indexes were calculated .Receiver operator characteristic(ROC) curve was adopted to analyze the diagnostic performance of CD64 indexes .Results Average fluores-cence intensity of neutrophil CD64 detected by CD64 reagents from Beckman company and BD company were 46 .16 ± 29 .21 , 28 .11 ± 17 .90 ,respectively ,with statistical difference(P0 .05) .The CD64 index of children in infection group (7 .06 ± 4 .20) was higher than that in the non-infection group(2 .93 ± 0 .79)(P<0 .01) .When CD64 index cut-off point was 3 .37 ,the sensitivity and specificity for bacterial infection diagnosis of CD64 were 93 .2% and 82 .9% ,respectively .Conclusion CD64 index may be served as an effective indicator for early diagnosis of bacterial infection in children .
