Can a child with RH neg blood come from parents that are A positive and A negative
What happens if a mother is Rh positive and a father is Rh negative is that they mother is given a RhoGAM shot when she gives birth. She will have to do this each time she gives birth, even if the births are not live.
yes
The rhogam shot is routinely given to mothers who are rh negative who may have rh positive babies. If you are rh positive there is no need to get the shot. However, if you are rh positive and get the shot it will not effect you or the baby.
of course. if mother is negative and father is positive, even no harm of first issue. but for second issue, it is necessary to inject anti-d.
The chance they will have a child is most likely high unless they use birth control. If the mother were rh-negative, that can sometimes cause complications, though it's usually manageable.
Yes, parents with blood group O positive can have a child with blood group O negative. This is possible if one parent is heterozygous for the Rh factor (one parent has both positive and negative Rh alleles), allowing for the possibility of the child inheriting the negative Rh factor.
Yes!
Yes. The child can either have an A or O blood type. The problem occurs when the mother is NEGATIVE and the child is POSITIVE, at which point the body create antibodies against the child as it passes through the birth canal (this is because the positive/negative stand for the presence/absence of the Rhesus factor, so if the mother lacks it (negative) then it will identify her child (positive) as "foreign" and attack it) In the chance of conceiving another child with a positive blood type, the already-present antibodies will attack the child unless the mother's antibodies have been counteracted. But in your case, there is no problem! :)
This can be a cause if the baby had a low blood count from birth or very shortly after, especially if this is not the first pregnancy. Hemolytic disease of the newborn can be caused by the mother's antibodies attacking the baby's red blood cells if the baby if Rh positive and the mother is Rh negative. The antibodies get into the baby before birth, however, so if the baby developed a low blood count at 3 months it would not be because of the negative/positive blood type.
No there is not. There is only a risk of Hemolytic Disease of the Newborn if the mother were Rh negative and the child Rh positive. In this scenario, during birth the fetal blood cells may enter the mother's blood stream of the mother. Since the mother doesn't have Rh antigens, her immune system sees the cells as a foreign substance and develops an anti-RH antibody to eliminate them. This would not do anything to the first negative child, however, if she gave birth to a second Rh positive child, the anti-Rh antibodies that are now in her blood stream would see the fetus Rh positive antigens as a threat and try to eliminate them. This would often result in death of the fetus or serious birth defects.
The negative blood comes from the rhesus scale. So type A negative blood means you are rH negative. This poses a potential problem during pregnancy if the mother is rH negative and the father is rH positive. In that case the mother will receive a rhogam shot during pregnancy and right after birth to prevent the potential mixing of blood between mother and child from causing a serious reaction in the mother's body.
When the father is Rh positive, it is possible that the child will also be Rh positive. Or, if the father is homozygous ++ or DD, then all of his children will be Rh positive. When an Rh negative person is exposed to Rh positive blood, in this case during birth, they will develop antibodies against the Rh positive blood. This means that if they come in contact with Rh positive blood again, they have antibodies which will attack the Rh positive blood. This is what happens when the mother is Rh negative and the foetus is Rh positive. There usually isn't a problem with the first pregnancy, because the mother might not have been exposed to Rh positive blood before. However, if the second foetus is also Rh positive, the antibodies in the mother's blood will attack the foetus. This ranges in severity, but can cause the death of the foetus. In most cases this is preventable - the mother can receive an injection of anti-RhD immunoglobulin during pregnancy or soon after delivery.
