I am O postive blood type my newborn is B postive what kind of problems could this cause?

Question

They did not explain much to me in the hospital other then telling me my white or red blood cells could have been attacking his.

Also we think my husband is bpostive but we are not sure he is from bosnia and said they never told him what his was he thinks his father is B postive though.

Answer 1

Because you are o that means that you're blood cells don't have any antigens on them which are the things that distinguish you from foriegn substances such as bacteria - it's part of the immune system. Sine you're kid is b it means that the antibodies that you're body makes against foreign substances will be made against b blood and also a blood. So there could have been a chance when he was still developing inside you that your antibodies attacked his but I wouldn't worry about it much, it should be alright :)

Answer 2

The answer is generally NONE and for a few reasons:
1. ABO antigens are not well developed at birth
2. The POWERFUL anti-B which you posses is mostly IgM and not capable of crossing the placenta (it's too big).
3. The small amount IgG anti-B which can cross the placena will attach to all cell types which carry the B antigen (not just red cells) remember: this is not well developed at birth. In many cases ABO mismatched babies are born with a negative DAT. Ask your Dr. what was the result of the babies IgG direct coombs test (DAT). Negative means no worry.
4. The worst cases of mismatch occur from other IgG systems (Rh being the most worrysome) and which can cross the placenta and do harm during the entire gestation.
Of course there are Rare Exceptions e.g. if there is an abnormal placenta, (where by IgM could have crossed ) Your Dr. would have used word's like "HDN" or "Hemolytic Disease of the Newborn".

Answer 3

The only thing I can think of is hemolytic disease of the newborn, which is when your antibodies cross the placenta and attack the child's red blood cells. However, this can only occur if the mother is Rh negative and the child is Rh positive (and certain other conditions have been met). You are Rh positive (the "positive" part of your blood type), meaning that your kids are not at risk.

It's not a problem if your children have different ABO blood types, because antibodies against those parts of the red blood cell are a type (IgM) that do not cross the placenta.

Answer 4

There is a disease called ABO Hemolytic Disease of the Newborn where O group mothers are exposed to A or B fetal blood and produce IgG anti-A,B which CAN cross the placenta and attack the fetal blood. A popular misconception is that HDN is only limited to Rh blood types, when in fact ABO and other blood groups can cause HDN. The good news is that ABO HDN is far less serious than the kind caused by Rh exposure.

Answer 5

There really isn't a problem. O is the universal donor, which means that if your baby needs a transfusion, you would be able to give the blood. It doesn't work in reverse, however. BTW, AB type blood is the universal recipient, and can take A, B, AB, or O blood.

Answer 6

confident it somewhat is accessible. in case your mom replaced into O blood group, you had a 50-50 danger of having O or B blood. regardless of if the two mom and dad had B or your mom had A blood, then you certainly might have 25% danger of having an O blood group. If the two mom and dad have been O, you should basically have O blood your self.

Answer 7

You could have an ABO incompatibility with erythroblastosis. This is usually a mild form, and the lab should have told you the diagnosis.

Answer 8

There is no problem. Maternal blood does not cross the placenta. The only problem would be if you were GIVEN his blood. I can't imagine how that would happen, though.
