La necesidad
El estreptococo del grupo B (Group B Streptococcus, GBS) sigue siendo una de las causas principales de septicemia neonatal de aparición precoz. Rates of maternal colonization have not changed, but universal antenatal screening at 35–37 weeks along with the use of intrapartum antibiotic prophylaxis (IAP) has resulted in a decrease of early-onset disease.1
Challenges remain, including:
Challenges remain, including:
- Riesgo de cambio del estado de colonización por GBS después del cribado a las 35-37 semanas de gestación2.3
- Some women with unknown GBS status presenting at Labor and Delivery unit4.5
- La profilaxis antibiótica intraparto basada en perfiles de riesgo expone a antibióticos al 65-85 % de las mujeres negativas para GBS6

La solución
- The Xpert Xpress GBS test is a qualitative in vitrodiagnostic test intended for the detection of DNA from Group B Streptococcus (GBS). The test is performed usinga dual vaginal/rectal swab specimen collected from pregnant females during antepartum or intrapartum.
- The Xpert Xpress GBS test is intended to aid in the diagnosis of GBS colonization to identify candidates for antibiotic prophylaxis.
El impacto
- Identify GBS colonization status at the right time, at the time of labor (intrapartum).4
- Identifying more women with GBS at the time of delivery and providing them with timely Intrapartum AntibioticProphylaxis (IAP) may result in a reduction of early-onset GBS disease in neonates.7
- Fast and easy-to-interpret results enable adequate IAP delivered to mothers with unknown status, which may resultin less impact on the newborn intestinal flora.8.9
