Antibodies in blood

[JoSands]

Hi. I've just had a letter from the hospital to say they have detected antibodies in my blood from the blood tests I had done at 13 weeks. Has anyone ever had this? If so please can you explain how it affected the pregnancy/baby?
This is my 2nd pregnancy, never had any problems with 1st pregnancy.
The letter was very vague and I'm now worrying about what it means and what will happen etc.
Any advice/info would be great, thanks!!

What sort of antibodies? Are you rhesus negative?

Antibodies for what?

Are you Rh Neg, and had the blood test done to see what blood type baby will be? If this is the case then its nothing to worry about, it just means you have to have an anti D injection at some point. Its really simple, straight forward and relatively common

I am Rh neg and have antibodies. I'm booked in for an anti-d injection at around 26 weeks, then I think there's another one just before the birth. You just need to be cautious that if you have any big knocks to your bump before your injection, you get checked out by the midwife.

Another (rare) possibility is that you have Anti-Ro/SSA or SSB antibodies. I had this and these can affect the baby's heart which means you need extra scans around weeks 16-24 to check the heart is developing properly. It's potentially serious however the actual chance of something happening is only 1-5%, which means you have a 95% of everything being fine!
