How dangerous is it...? - Page 2

¨ok, I may be confused, if you're talking about DH having both ++ genes then sure I bet you're right. But I have never heard of getting that kind of typing done?? is that something you got because of your situation? Everyone I know just knows they're one or the other.¨amiev

Yes, I did have to get more specific typing done. If the baby´s dad is homozygous positive he would have 2 positive alleles on his blood, so ++, but if he is heterozygous, he will have *-. The heterozygous guy could father a rh - baby. Of course my dh is homozyg for ´+, lucky me A man with 2 positives can only have a positive baby.

There are cool things like the du factor though that can make an rh negative woman unlikely to ever develop antiboides. There are any variations and weird things about this whole issue that they haven´t even learned yet. There are definitely worse problems than being isoimminuzed though!

Interesting discussion!

More thoughts to add:

Having an indirect Coombs done on the maternal blood will determine the presence of antibodies in her blood. If positive, an antibody ID would then be done.

RhoGAM is thought to "cover" those with the anti-D (that is what it is given for), which most Rhneg people have, but doesn't protect moms (therefore babies) with other antibodies.

My children are both RH-negative, so I didn't need the rhogam after birth, but my grandmother is also RH-negative and had seven children without rhogam, including at least several who were +. She did not have a problem until the sixth child, who required a blood transfusion at birth but survived.

It depends on where the typing's done. At some labs, they do check homozygosity. When my Dh was typed for Kell, they checked his homozygosity v. heterozygosity because for us it would make a difference.
