Group B Strep Test: What To Expect And How To Prepare

The Group B Strep Test (GBS) test is a crucial part of prenatal care during pregnancy. In this article, we will explore what the GBS test entails, why it is essential, and how to prepare for it.

The Group B Streptococcus (GBS) test is an important prenatal screening. It checks for the presence of Group B Streptococcus bacteria in the vagina and rectum of pregnant women. This bacteria is common and typically harmless in adults but can pose severe risks to newborns if transmitted during childbirth. A GBS infection in newborns can lead to severe complications such as pneumonia, meningitis, and sepsis, which can be life-threatening. This is a test conducted between the 35th and 37th week of pregnancy. It is a precautionary measure that helps doctors decide if antibiotics are necessary during labor to prevent the newborn from acquiring the infection. This article looks into the significance of the Group B Strep test and the testing process. It also discusses the implications of test results for both mother and baby, offering an insightful guide for expectant mothers and their families.
