Dad's Giving Blood?

Mom won’t be the only one giving blood. Mom recently found out that she has an A negative blood type. In general, this is not of concern in a person’s daily life, but it does when a female becomes pregnant. If a negative mom mates with a positive dad, the baby has the potential to be positive. This difference can potentially cause RH disease. So, dad’s blood needs to be tested to confirm what blood type he is. Dad has documentation for his blood, but a previous doctor’s note is a little illegible and may not meet mom’s doctor’s requirements. Dad’s notes are that he is A positive.

RH disease is basically when the mother’s body develops antibodies to the RH positive blood. Although this is generally not an issue during a first pregnancy; it can be for future pregnancies as the antibodies become more abundant in the mother’s body. The mother’s and baby’s blood remain separate during pregnancy, but may be mixed if an amniocentesis is performed and/or during birth and a few other instances. Prevention of the antibodies forming is treated by giving the mother a shot between the 26 – 28th week of the pregnancy and then again right after birth. The shot basically inhibits the mom from creating antibodies which could cause the mother to fight the baby.

We will find out more during our next doctor visit on April 13th, but attached are a couple of links that better explain this new development.
