Acridine orange stain--a rapid method for diagnosis of neonatal septicemia

The present study included 150 newborns; 100 clinically septic and 50 clinically aseptic who served as control. Out of 100 clinically septic newborns, blood culture was positive in 33 (33%), serum CRP was positive in 64 (64%) and acridine orange stained buffy coat smear was positive in 76 (76%). Serum CRP was found to be the most specific (specificity 96%) and acridine orange stained buffy coat smear examination the most sensitive (sensitivity 94.3%) test for diagnosis of neonatal septicemia.
