Antibodies

[Thistles24]

Hi all, just wondering if anyone has been told they have antibodies in their blood after routine blood tests?
I'm 18 weeks pregnant with DC3 and didn't have any during my first 2 pregnancy, but when I was at my 16 week appointment the midwife read out a long list of antibodies I've tested positive for. She seemed a bit vague about it, and said they'd check what the levels are at 24 weeks as there was no information about the levels, just the fact they were present.
I've had a quick Google and the only one I can remember that she listed was K, which seems like it could cause problems and I should have levels checked sooner, DH also should be tested. Anybody have any experience?
TIA

I have no experience but just found this x

I have Anti-S antibodies. My levels were checked every 4 weeks during the latter stages of pregnancy but were always low.

It did mean that the hospital were very cautious when DD arrived and (in my view) they overreacted when DD started showing signs of jaundice and insisted on doing formula top ups (I was hell bent on EBF). The inference seemed to be that jaundice relating to antibodies needed more firm handling than it would have otherwise.

Anyway, DD is 11 months now and both she and I are absolutely fine.

The most important thing I had in mind was that they had cross-matched blood readily available during my c-section (as ideally you want a blood transfusion from a donor with the same antibodies).

Im 17 weeks pregnant and have anti nuclear and anti ro antibodies. Both can be dangerous in pregnancy. Anti nuclear can cause placental insufficiency and therefore I've been proscribed aspirin throughout my pregnancy to make it easier for blood to pass through my placenta. Anti ro can cause congenital heart block and needs to be monitored, so I have weekly scans with my consultant to check my baby's heart. These antibodies will never change in my blood so repeat tests are pointless. I knew pre pregnancy so was able to request a referral at my booking appointment, as advised by the doctor who did the original tests. My midwife knew nothing about my condition as it's very rare, so if you have either of those you need to be referred immediately as monitoring begins at 16 weeks. I'm classed as a high risk pregnancy and must be consultant led and give birth in a hospital with doctors. I'd ask for a consultant to review my results in anyway as I know a number of others can also be a risk. Feel free to message if you need any advice.

If you have Anti-K you should have titres measured every 4 weeks up to 28 weeks then after that they should be checked every two weeks. Partner testing is usually performed to assess the chance of your baby being K+ and whether they are at risk of HDFN or not.
It might be worth chatting with your mw again and asking for more information.
