I had my 12 week appt yesterday and my OB discussed getting my rhogam shot since my blood type is O- and DH is A+. Did this with my first, so no biggy. But he also told me that there is a new blood test that can find out if the baby's blood is negative or positive, and it just so happens that it also tells the sex of the baby! And it can be done at my next appt! Have any of you ladies heard about this or are getting it done? I tried to find information about it online, but didn't find anything.
TIA!
Re: If you are RH negative, come in
I've never heard of that. Is he talking about a CVS test maybe? I wouldn't do something like that just to know the gender early or avoid a rhogam shot.
ETA: never mind just saw your response OP. No one told me about it at my last appointment, so I guess they don't offer it at my office.
That is funny! I'm pretty sure it would be covered because it would take the place of getting the rhogam shot, which is covered. Will definitely be calling the doctor in the next few days to find out more about it.
Google told me that a test for fetal RHD genotyping is offered through the same company that does MaterniT21 testing. So it's a very similar test, but not the same one.
Sorry for non-linky - but here's the site I found. It's a bit sparse on information as to how they actually do it, but it's the general idea. I'll see what I can find on PubMed and update if I find anything for the technically-minded ;-)

So that was quicker than expected:
https://www.ncbi.nlm.nih.gov/pubmed/23225162
Basically they do a DNA analysis on the fetal DNA from the maternal blood to look at the RHD genes and a couple genes on the Y chromosome. So you will definitely find out sex too!
