Kell Antibodies, Need expert help
martinawilliams posted:

I am currently 15 weeks pregnant with our 2nd child. Our 1st child was very healthy when she was born.

We were required to do blood tests and the results are back. I am K neg while my boyfriend is K positive. Can anyone tell me what are the implications and negative affect of this findings on our unborn baby? What are the possible outcomes?

Thanks very much
Robert O Atlas, MD responded:
The real question is whether you have antibodies to the Kell antigen. My assumption is since you are asking you do. Most don't know their status.

It can be not a big deal or it can cause some significant risks of great harm to the growing fetus. You really need to be refered to a maternal fetal medicine subspecialist is is well trained in this area.

you may only need to have blood work done every month to having to have ultrasounds weekly ( to look at a blood vessel in the brain of the baby. it can help determine whether the fetus is anemic, low blood count).

If the fetus is thought to have anemia, then the maternal fetal medicine physician may need to put a needle in the umbilical cord of the fetus and see what the fetuses blood count is and possibly give a blood transfusion.

So, as you can see, it can be not much or it can be quite dangerous to the outcome of the fetus.

I wish you the best. please let me know if there is any other information I can provide to you.
