The Need
In the U.S., Group B Streptococcus (GBS) remains a leading cause of early onset neonatal sepsis. 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.1,2
Challenges remain, including:
Challenges remain, including:
- Risk-based IAP exposes 65-85% of GBS-negative women with risk factors to antibiotics. This has been linked to emergence of resistant strains3
- Up to 50% false negatives when testing with agar alone4

On-demand molecular testing — an ideal solution:
On-demand molecular testing — an ideal solution:
- Moderately complex testing with < 1 min hands-on time
- Reduces lab's work for antenatal screening
- Random access ensures any test on the menu can be run anytime, without the need to batch
- System designed with Early Assay Termination (EAT) with positive samples reported STAT
- As soon as positive sample is confirmed, software concludes test and reports immediately.
The Impact
A molecular in vitro diagnostic, Xpert GBS LB is designed for use in the clinical lab. It allows users to simply perform ONE easy step and the GeneXpert System does the rest.
