My sister just had a baby and they tested her blood as O-. Both my parents are A+ and my mom was tested when she had my sister to make sure she didn't need that shot they give when the blood types are different and she didn't need a shot and neither did my sister. She only found out her blood was O- after the baby was born. Could they have messed up the blood test? If they didn't, did someone else mess up because my sister had no idea her and the baby would have this sort of problem. Wouldn't the doctor let her know about it?

I'm just wondering why they didn't catch this earlier. The baby is AB+ like his Dad. Hmmm and if my sister is O- and my MOM is A+, why didn't she need the shot after she was born and wouldn't my Mom have been told about it? There are 6 of us and 4 are A+, I'm not certain about my youngest 2 sisters.

O- is the "universal" blood type. Your mother didn't need the shot because she is +, Your sister didn't need the shot because her blood type is compatible with any blood type. Yes the doctor would let her know if there were anything to be concerned with and they test very early on for RHfactor.

If your sister and the baby are both O negative then what is the problem? There is only a problem when the mother is negative and the baby is positive and it doesn't matter WHAT blood types your parents are your sister can STILL be negative. Both of my parents are postive, my sister is postive, even my step sisters are positive, I am O negative. My daughter had complications at birth because she was positive, I had the shot years ago but for some reason it didn't work (sometimes it doesn't) . They didn't test me to find out if the shot had worked when I got pregnant so they didn't give me the shot again...which is why the complications.

Im not really too sure as to what you're asking...
Everyone, whether your A, B or O, carries a recessive O gene. For example, I am A- my hubby is B+, our daughter is O+. She received the recessive O gene from both of us.
If you are asking about a case of Rh incompatability, If your sister is Rh negative, yes she should have had the Rhogam shot during her pregnancy. If the baby is Rh positive, as you state the baby is, your sister should have had another dose of Rhogam. The reason for this is to prevent your sisters blood from developing antibodies against the foreign Rh positive blood, if she were to become pregnant again, and that baby is Rh positive. If by small chance the baby's blood crosses with your sisters blood. her body will try to attack the Rh positive blood as if were an intruder.
I hope i answered your question.

The first thing they check you for at your ob/gyn's office before std's when they find out you are pregnant is your blood type! The Rh factor is only a bad thing when the mom is O- and the baby has a different blood type. I am O- and I have to get a shot during pregnancy and then one after wards if the baby is not O-. Also, this usually only causes problems after your first child, meaning it takes the whole pregnancy for the mom to produce antibodies against a baby. Hope that helps.....if not, then you can search or Rh Factor online!

Yes. To read more about it, read 'Kidnapped at Birth?' by Louis Sachar.
Anyways, it is very rare. One out of a million has blood type O-.

O negative is the most common blood typeby far,so it's not unusual.
