Strep B Testing

Beta Streptococcus (the full name is Group B beta-hemolytic streptococcus; we call it GBS or Strep-B) is a bacterial strain found in up to 30% of women. It is a normal inhabitant of the vagina and is not considered an infection. There are no symptoms and usually no associated vaginal discharge.

Following the guidelines of the American College of Obstetricians and Gynecologists (ACOG), we perform a test for Strep B at about 34-36 weeks. If the test is positive, we note this in your record and we instruct you that you will need intravenous antibiotics when you are admitted to the hospital in labor, or if any premature labor develops.

If you test positive for GBS, please mention this diagnosis to your labor nurse at the time you are admitted in labor or if your membranes have ruptured. This helps to ensure the promptness of your treatment.
