Do You Need A RhoGAM Injection?

By the end of your twenty-eighth week of pregnancy, your baby will be packing on the pounds as your baby nears that date when they meet the outside world. Some women during this stage in there pregnancy will have to get a shot if the blood type they have is RH negative blood type and the father is a RH positive blood type, or vice versa. Your physician probably told you in the first trimester whether or not if this shot was needed. Usually during the first pregnancy your doctor may not give the RhoGam injection if you are RH negative. The reason behind this is because your body will not have enough time to have built up antibodies against the unborn child. Any pregnancy after that will require a RhoGam injection because the body has a plentiful supply of those antibodies from the previous pregnancy.

Blood Types

Everyone is born with a specific blood type. RH negative blood is basically blood that doesn't have the RH factor. If you are RH positive then you don't have to worry about taking the injection at all. If you are RH negative then the RhoGam injection will be recommended so further complications don't arise during your pregnancy. Examples of RH positive is A+ or B+. RH Negative examples are A- or B-.

RhoGAM Injection

What is a RhoGam injection? This injection, RhoGam is RH immune globulin and used for the purpose of the baby having RH positive blood and the mother having RH negative blood. The mother's immune system would then recognize the baby's blood as a foreign material and try to attack it like it would a virus. That is why this injection is important because it creates RH antibodies and keeps both the mothers blood type and the baby's from conflicting with each other. Within the 28th week mark of pregnancy, the baby's blood and the mothers will most likely cross through the umbilical region and this injection will stop a likely conflict.

There are many complications that can arise without this injection. Rhesus disease or hemolytic disease of the newborn can be prevented with the use of this medication. The injection is given at 28 weeks. After delivery your baby will have his or hers blood type tested. If the baby's blood type is RH positive then you will receive another RhoGam injection. If the baby is RH negative then another injection will not be needed. If bleeding occurs at any time during your pregnancy, this injection will be used during that time. The side effects are mild and the risk of not taking the injection is not worth jeopardizing your baby's health. Just discuss with your physician any questions regarding the shot.
