It didn't sit right with me at all, I've become an avid researcher of all things preg related and when i'm not sure I come to you girls for advice. Also she's a nurse.
It seems to be mentioned only in American websites. In Australian ones, amniocentesis is considered a risk factor for RH negative women, rather than a diagnostic tool.
She might be confused with the procedure they do to check if bub is aneamic caused from a certain antibodies RH neg women are at risk of if they have not had anti-d in the past and have made antibodies from exposure. You test positive for this when antibodies are tested early in pregnancy. It can be neccessary to do a transfusion on bub prior to birth but this is extremely rare maybe thats what she is calling an amniocentesis. I'd have ask the specific antibody from an Ob at work. It use to be a reason why lots of RH negative women had stillbirths in the dark ages before anti-D was given.
I'd have to go ask as in 5years of midwifery I have only seen it once and the mummy was transferred to a large Sydney hospital for this to be done so we didn't follow her through from her transfer from us. I know it was successful but I don't think bubs Hb (haemoglobin) was tested from the amniotic fluid.
I've heard of this test being done in the hossie I used to work at, but it is not to test the bub's blood group. If mum's antibodies test postive, they are tested very regularly and if they are found to be increasing, they like to take a sample of the amniotic fluid to test bub's bilirubin levels. If neccessary they will then take a sample of blood from the umbilical cord to test the heamoglobin (as anti-D antibodies destroy bub's red blood cells), and if it is low enough they will transfuse bub. I have looked after babies that have had this done multiple times during pregnancy. But it is not common.
Thanks ladies,
That's what I thought, I've had plenty of anti d shots & had a BT before I fell Preg with this bub that showed I hadn't developed antibodies so all should be fine.
She sometimes says things to scare me I think.
Just wanted to let you know I have 3 boys and only had the Anti D with all of them. My first pregnancy ended in a miscarriage so I had the Anti D after that and then with each pregnancy first one at 28 weeks and next Anti D injection around 34 weeks from memory.
On a side note all my boys are o- themselves so turns out I probably didn't need them as both DH and I are o-.
I am RH neg, have 3 children and got a shot before DD2 was born. I can't even remember it being an issue for the first two. Bad memory maybe, but it was never a huge issue. Anti-d was the answer.
