I was diagnosed with anti-kell during my second pregnancy. It is hard to find information about it, but a lot of the same information applies with rh sensitization.
First, you'll probably need to find out how you got sensitized. If you have had a blood transfusion, that might be it. If you haven't had a blood transfusion, your mw (or doc) will test your dp. If your partner carries the antigen (mine did) they will further test to see if he is homozygous or heterozygous. If he is homozygous, all your children will have the antigen (kell) that you make the antibodies (anti-kell) for. My dh is heterozygous, which means that, statistically, our children have a 50/50 chance of having the antigen. All three have had it though, so so much for statistics.
There are a few routes you can take. If it is an issue with your dp being heterozygous, you can do an amnio to see if the baby does indeed have the antigen. You can also go the route of checking titer levels (above 1:32 warrants further observation) weekly sonograms to measure the blood flow through the cerebral artery in the brain. They can detect if the babe is getting anemic fairly well this way. If they babe is getting anemic (neither of mine were) they can do a blood transfusion through the umbilical cord. They can do this until the risks of the baby being born outweigh the risks of the baby staying in. My first sensitized baby was born at 40 weeks and my second we choose to induce at 37 weeks when it looked like him might be getting anemic.
After the baby is born, depending on whether they were already anemic in the womb will dictate what course of action. They watch for pathological jaundice (which is very different from normal physiological jaundice) The baby might need to be on bililights, have a blood transfusion or have ivig treatments.The good news
is that there is a ton of things that can be done about this. The outlook with the techonology available is amazing. And, some cases just aren't as severe as others. My first sensitized baby had to do the lights for three days and then we took him home with a biliblanket. He roomed-in with the lights and never went to the nicu. My second was extremely healthy and his bilirubin levels were never even enough to warrant lights. Sometimes the anti-bodies don't "see" the baby's antigen until late in the pregnancy and sometimes not at all.
I am sorry this is so long, please let me know if you need anymore information. I have a ton stored in my brain
Google Dr. Kenneth Moise. He has written stuff about kell
