These antibodies then attack the unborn baby’s red blood cells. But when a mother is Rh negative and her fetus is Rh positive, the mother’s blood may produce antibodies against the baby’s Rh factor. On its own the Rh factor does not cause health problems. Mild transfusion reactions are not dangerous, but a severe transfusion reaction may be deadly. But if an Rh negative (RhD-) person receives Rh positive (RhD+) blood, their body reacts, making chemicals (antibodies) to defend against the foreign Rh factor. If this is not available, they may be given blood from a compatible blood group. Otherwise a reaction to the ‘foreign’ blood may occur. When someone needs a blood transfusion it is preferable that they are transfused with blood from the same ABO and RhD groups as their own. For example, someone’s blood may be ‘O positive’ (written O+) and another person may be ‘AB negative’ (written AB-).

Each blood type is also further identified by a plus (+) or minus (-) sign, which designates the Rh status of the blood. In Australia, around 80 per cent of people are Rh positive.īlood is classified into groups, the most well-known being the ABO system in which a person’s blood is recorded as either A, B, AB or O. Most people have the Rh factor and test Rh positive (RhD+), however, some people don’t have the Rh factor and so are Rh negative (RhD-). A person’s blood is either Rh positive (has the RhD protein) or Rh negative (doesn’t have the RhD protein).

What Is The Rh Factor? Why Is It Important?.

Once you have produced the RH antibodies in your body the Rhogam will not help, and your next baby may need a blood transfusion through the umbilical cord to survive. Rhogam is also necessary if a mother is experiencing any invasive testing such as amniocentesis and chorionic villa sampling. For Rh negative mothers, Rhogam is necessary in the case of miscarriage, abortion, ectopic pregnancy, molar pregnancy, and with bleeding that may occur during pregnancy.

If she is Rh negative, her baby could be positive or negative, and she should receive a Rhogam injection to prevent any Rh antibodies from forming. If a woman is pregnant, it is important for her to find out her blood type and Rh factor early on. Whatever your current decision is, find out your Blood Type and RH factor and if you are RH negative make sure you get Rhogam. It is recommended that you receive a Rhogam injection within 72 hours after an abortion, miscarriage, or any abnormal bleeding. These RH antibodies can cross the placenta and destroy the baby’s red blood cells. This would not be a problem during a first pregnancy but could cause a serious problem for future pregnancies if those babies were RH positive. If this occurs, it could cause the mother’s body to produce RH antibodies. Usually, the baby’s blood and mother’s blood would not mix, but a small amount of baby’s blood could encounter the mother’s during delivery or if she is experiencing any bleeding or abdominal trauma. If the baby is Rh positive, complications in pregnancy can occur. RH negative blood type usually does not affect a person’s health but can affect a pregnancy. If a woman is RH negative, her baby may be positive or negative. This means that though someone’s parents may not have the Rh factor, they could still inherit the gene themselves. If your blood type is negative, then your blood cells lack the Rh protein.” Like blood type, the gene for Rh factor is also inherited, even though it is a recessive gene.

If your blood type is positive, then your blood cells have the Rh protein. What is the Rh factor?Īccording to the American National Red Cross, “the Rh factor is an inherited protein that can be found on the surface of the red blood cell. For more information on blood and blood type, visit.

The type of blood that one has determines how they can give or receive a blood transfusion. Blood type can be determined by “the presence or absence of certain antigens – substances that can trigger an immune response if they are foreign to the body.” Blood type is inherited, meaning that people get it from their biological parents. There are 8 blood types: O positive, O negative, A positive, A negative, B positive, B negative, AB positive, AB negative. It is important for everyone to know these things for the sake of their health, but it is especially important for women who are or who might be pregnant. Not everyone knows their blood type, and even fewer are aware of whether they are impacted by the Rh factor.
