Ronni, I'm not exactly sure what Group Strep B is, but my doctor does the test at 36 weeks. I think its just a quick swab, not painful or anything. Sorry I don't have more info, but I don't think its anything to worry about and its probably OK that you haven't gotten it yet.

 

Group B Strep Test - February 2

The group B streptococcus (GBS) bacteria is usually harmless in healthy adults, but it can cause a relatively rare but very serious infection in newborns. (Group B is different from group A strep, the bacteria that causes strep throat.) Between 10 and 30 percent of pregnant women carry GBS bacteria in the v____a or rectal area, where they may pa__s it to their babies during labor or birth. With proper prenatal testing and treatment during labor, though, the risk is small. Without treatment, one or two out of every 200 babies born to "GBS positive" mothers would become infected with the bacteria and develop what's called early-onset GBS disease. The consequences can be very serious. GBS disease can cause sepsis (an infection in the blood), pneumonia, and meningitis in newborns. Some of these babies, particularly those with meningitis, will have long-term health problems such as hearing or vision loss, cerebral palsy, or developmental disabilities, and about 5 percent won't survive. While this sounds really scary, the good news is that getting screened when you're between 35 and 37 weeks of pregnancy and receiving antibiotic treatment during labor if you test positive will greatly reduce your baby's risk of becoming infected. For the test....Your pract_tioner will take swabs of cells from the lower end of your v____a and rectum (this won't be painful at all) and send them to a lab to be grown in a culture that will identify whether GBS bacteria is present. Your results should be available in two to three days, and your pract_tioner will give them to you at your next prenatal appointment. If she doesn't tell you, be sure to ask. (It's good to know, in case for some reason your prenatal chart isn't available when you go into labor.)
