Clinical Trial: Obstetrics and Gynecology

Group B Strep (SAGA)

Full Name

An evaluation of discordance between antepartum Streptococcus agalactiae(GBS) screening at 36 weeks, GBS screen at time of labor and postnatal GBS screening of the neonate


Group B Strep (GBS) DNA-PCR probe collection is usually performed at the 36 week OB-GYN visit. DNA-PCR probe is resulted as negative. Those who test negative for GBS will be invited to participate in the study. Three specimens will be collected for lab analysis for this study:

  1. Rectovaginal GBS swab from mother at time of admission
  2. Ear GBS swab from neonate after delivery whether delivered vaginally or by unscheduled cesarean
  3. GBS swab of placenta after delivery

The participant will be given a $25 gift card as compensation for their time and effort. All lab specimen costs will be covered by the research study, and not billed to the patient.  


To learn whether additional testing for GBS and/or antibiotic treatment is needed in women during the labor process when they have tested negative for GBS earlier in pregnancy.
