ANTI-D in Blood before I've had injection. Help

[nellieellie]

I've also put this in the Health thread as desperate for info. I am rhesus negative and had an anti-d injection as standard when pregnant with my 18mth old. I am now 14wks pregnant and after blood tests have just been phoned up by the Dr to be told that the test detected anti-d in my blood. The Dr asked me whether I'd had an injection in this pregnancy - I haven't. She seemed bewildered by it and when I queried what this meant and whether it was "bad" she just said they didn't know they needed to do another blood test. I am now worried sick. If there is anti-d left over from previous pregnancy can this have affected the baby? Normally the anti d injection isn't till 28 wks so must be some reason why given late rather early in pregnancy...Please any info re this would be much appreciated. I am not going in for 2nd blood test till Friday, and god knows how much information I'm likely to get then - my guess is not much.

Yes, you cab definitely have it earlier.

I'm A-, and both of my children are O-, so there's never been a problem for me, but if you are really worried call your MW. I'm sure everything will be fine, and now they know this they can monitor you as neccessary

Maybe they've mixed up your sample with someone else's. Do you have a common surname?

They won't have mixed your blood sample up with anyone's. Every part of the label has to be correct - name, dob, nhs number. If one letter/number is wrong the lab will send it back.

Its possible that you had a silent bleed early on in your first pregnancy and some fetal blood got into your circulation. If so an anti-d injection at 28 weeks would have been too late to be effective as the antibodies would have formed, funny that they didn't pick it up later on in your 1st pregnancy though.

If you have got antibodies in your blood - they know and can monitor you and baby. They will keep an eye on your titre levels to make sure they don't go to high. If they do go high then I believe there are things they can do such as in-utero blod transfusions for baby - but that is a worst case scenario and unlikely that things get to that stage. But even if they do, its not that awful. A friend of mine had to have regular in-utero blood transfusions to her 2 babies when pregnant and has 2 perfectly healthy children.
