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.
