EBB 261 - Ask Me Anything about Group B Strep

Update: 2023-03-29


In this bonus episode, we wrap up our 2-part series on Group B Strep in Pregnancy, where I answer some of your questions following the first two episodes.

Here are the questions answered in this bonus episode:

  1. Is it possible to retest between an initial GBS swab and going into labor? Are there things that can be done to get a negative test before labor occurs?
  2. If you are GBS positive in one pregnancy, are you likely to be positive in subsequent pregnancies?
  3. Discussion about an important limitation to one of the studies in our GBS update.
  4. Discussion about risk factors and the “Other Risk Factor” approach vs the Universal Screening approach
  5. Is there evidence for screening for GBS twice in the same pregnancy?

Make sure you listen to Part 1 and Part 2  to review the updated GBS research.
