Dont Know What It Is

I recently found out that im pregnant and im so happy but worried at the same time. My last pregnancy didnt go so well as we found out that our baby had something in its blood called 'Weak Anti-K' and noone could explain to me what it was all they kept saying was that its very serious. But they told us that my partner had to get tested to see if he had something in his blood that could 'cure' it, he didnt. But still noone could tell us what the problem was so we decided to terminate as everyone was saying it was serious.

So im worried in case we have the same trouble with this pregnancy.

Im wanting to know if anyone has heard of this 'Weak Anti-K' or experienced it as I would like more information (the internet is no help)

Thankyou very much :)

anti kell antibodies can cause problems for baby. Basically these antibodies can cause anaemia in baby (called Haemolytic disease of the newborn - HDN) and if the levels aren't monitored it can ultimately result in death.

There are 2 ways of mums getting these antibodies, the first one is having a blood transfusion from a person who was kell positive or from having a previous pregnancy/termination where the baby was kell positive. Both chances are very low as only 9% of the population are kell positive! These days they monitor the kell group of blood donors and won't give kell positive blood to ladies under 60.

Once these antibodies have been detected, your partners blood should be taken to determine his blood group. If he is 'carrying' the kell antigen then there is a 50:50 chance that baby will be affected by the kell antibodies in babies blood. If he isn't carrying the kell antigen then baby 'should' be ok.

Next, the docs have to determine the levels of antibody in blood. if levels are high 1:256 (if levels are less than 1:32 than baby should be ok). .

If baby starts to become anaemic then they can do a blood transfusion from 20 wks and if the baby starts to become severely affected then they might deliver baby at any point after 28wks.

i dont know how much help this is going to be but i hope it does a little
