O negative Rhesus Negative question

    Just found out this is my blood group. Am pregnant with my 1st child. Have checked out wikipedia but can't find any information solely on O neg with rhesus neg ( mainly stuff on O group and rhesus neg).

    Anyone know if this is a good thing or a bad thing? I know I can only get a transfusion of O neg but does it have to be rhesus neg too. My sister is a blood doner but has been on warfarin for the last 6 months due to pulmonary embolism ( the pill, shes fine). So I don't think I can call on her and I think this might be very rare group combo.

    Thanks for any info.

    When you say you've got type O neg blood, the negative part actually refers to rhesus neg. You should only receive O- transfusions, if you're exposed to O+ blood you can develop antibodies to the rhesus antigen which can cause reactions in future exposures.

    There's some basic info here

    Doh!

    Thanks very much. I was afraid it was really rare and I would have trouble with donors.

    Grawns you will get the anti d injection after your baby is born.

    Only 8% of the population are O neg/ We're universal donors (ie can donate to anybody) but we can only receive O neg blood. That's why it's extra important for O neg people to be blood donors. Unfortunately I can't anymore as I lived in the North for a few years :(

    The anti d injection isnt given if hte child is rh negative too.

    Ideally they test the partner before birth to find out his blood type, if he's neg the child will be neg, if he's pos it'll be found out when the child is born.

    That's not how it happened with me Tree. They did test the baby's blood type but gave me the injection before the results came back! It turned out the baby was O neg too... though maybe it was because there was some bleeding for a few days before she was born and they didn't want to risk waiting any longer:confused: Second baby was O + so it was needed.
