Blood Groups - do you know yours/your family's?

[Jodee]

I was trying to find a record of ds's blood group recently and couldn't find it - it isn't noted in the red book. I know mine, I'm O Rh Neg, this is because I have given blood.

Would my GP have ds's blood group on record, I presume they must have found this out at birth?

And DH doesn't know his - he is reluctant to give blood, despite my twisting his arm, could he ask for a blood test from his gp just to find out this info?

i just feel it is knowledge that we as a family should know.

To be fair, it is possible (I think) for the blood group thing to indicate a paternity problem when there isn't one, thanks to chimerism. I think it's pretty rare, but still ...

Blood transfusion service seems the cheapest ,most unstressful ,most civic minded way to find out the info dh and me both b+.
Carolinamoose - my mum always gave blood and in such a way that It was a right of passage for me when i got to be 18 . Only grown ups can give blood . Pity they cant take it any more.

I agree NQC, I think thats why they stopped telling people, there was no clinical need to know what the child's blood group was routinely, but it was causing unnecessary anxiety when people thought 'how can this be my child then?', because presumably the genetics is more complicated than if mum is this and dad is this child can only be this.

Janh, isn't it possible for the reaction to be caused with the first rh +ve baby if there's been a bleed during pg?

This is what I was told when they gave me anti-D when I was pg with ds.

I'm B negative
DH is A postitive
DD must be something positive as I had anti-D after her birth

It is the first baby that causes sensitivity to the positive blood. This can then cause problems in subsequent pregnancies which is why anti-D would be given i.e. the first pregnancy is usually ok but the ones that come next can have problems if not managed properly.
