Blood Culture and Bacteremia Predictors in Infants Less Than Three Months of Age With Fever Without Source

Abstract

A positive blood culture rate of 2.2% was found in infants less than 3 months of age with FWS. C-reactive protein, white blood cell count, and absolute neutrophil count were not good bacteremia predictors. We recommend obtaining a blood culture in infants less than 3 months of age with FWS, particularly those patients considered "not well-appearing" and those with leukocyturia and/or nitrituria.
