GROUND: The polymerase chain reaction (PCR)-based test to detect herpes simplex virus (HSV) genome in cerebrospinal fluid (CSF) has become the test of choice for diagnosing this infection. The utility of this test in young infants undergoing sepsis evaluations is unknown. OBJECTIVES: We sought to identify the factors that prompted physicians to include HSV PCR in their evaluation of young infants undergoing lumbar puncture. In addition, the impact of ordering this test on patient management was assessed. METHODS: This case-control study included infants 0 to 60 days who were evaluated by lumbar puncture at the Alfred I. duPont Hospital for Children over a 5-year period. Case patients had CSF HSV PCR ordered as part of their evaluation and control patients did not. RESULTS: Eighty-eight case patients and 83 control patients were identified. The median patient age was 12 days and most patients (55%) were male. Both groups were similar in demographics. Herpes simplex virus infection was d
