Screening for group B Streptococcus (GBS) at labour onset using PCR: accuracy and potential impact - a pilot study.

This study highlights the fact that a large number of GBS carriers in labour, who could potentially infect their babies, do not receive IAP, and most of their babies do not receive added surveillance in the neonatal period for EOGBS disease. It also confirms that PCR testing at onset of labour is a highly sensitive and reliable test that identifies the women who are GBS carriers in labour and hence need IAP. What the implications are of these findings for clinical practice and/or further research: Timely provision of IAP for the appropriate woman is possible by adopting universal GBS screening at the onset of labor using GBS-PCR. This would involve additional costs to health care facilities and added work to laboratory personnel.
