I'm not sure. I don't understand why they have to test for it with every pregnancy to be honest. I figure if you are a carrier once you always will be but they test me for it every time. So they just give me antibiotics while I'm in labor. But I have had all vaginal deliveries.
They just have to take precautions to prevent lawsuits. There's never telling what can happen and what can be possible... in other words, I have no CLUE! That is a VERY interesting question. I hope someone here can give you more insight. But what I said is probably part of it.
