FAQs
What does it mean if you have Rh factor? ›
The positive or negative sign next to the blood groups is known as the Rhesus (Rh) factor. The Rh factor is an inherited protein that can be found on the surface of the red blood cell. If your blood type is positive, then your blood cells have the Rh protein.
Is having Rh factor good or bad? ›Each blood type also has a positive or negative factor. The positive or negative next to the blood type is your Rh factor. Your Rh factor doesn't cause problems or hurt your health in any way. It only becomes important when blood types are mixed together, like during pregnancy and childbirth.
What happens if Rh factor is positive? ›If you're Rh positive, you don't need to do anything. If you're Rh negative and your baby is Rh positive, your body could make antibodies that might be harmful during another pregnancy. Take these steps: If you have vaginal bleeding any time during pregnancy, contact your health care provider right away.
Why is Rh negative blood so rare? ›For example, if someone's Rh factors are both positive, it is not possible for his or her child to have a negative blood type. Only people with at least one Rh-negative factors will have a negative blood type, which is why the occurrence of Rh-negative blood is less common than Rh-positive blood.
What problems can the Rh factor cause? ›During a pregnancy, Rh antibodies made in a woman's body can cross the placenta and attack fetal blood cells. This can cause a serious type of anemia in the fetus in which red blood cells are destroyed faster than the body can replace them.
Should I worry about being Rh-negative? ›Most of the time, being Rh-negative has no risks. But during pregnancy, being Rh-negative can be a problem if your baby is Rh-positive.
Does Rh factor affect personality? ›There's even a prevailing belief that certain blood types do better with a blood-type specific diet. But to date, no studies have found a correlation between blood type and personality in a large study group.
Can Rh negative cause miscarriage? ›The Rh-negative blood type can pose risks during pregnancy, including increasing the risk of miscarriage or stillbirth in the second or third trimester. Nowadays, women with a negative blood group are preventively given the Rho GAM injection, to reduce the risk involved.
Who is at risk for Rh factor? ›Rh incompatibility develops only when the mother is Rh-negative and the infant is Rh-positive. This problem has become less common in places that provide good prenatal care. This is because special immune globulins called RhoGAM are routinely used.
Is Rh positive a problem for pregnancy? ›More than 85% of people are Rh-positive. The Rh factor does not affect a person's general health. Problems can occur during pregnancy when the baby's blood has the Rh factor and the mother's blood does not, however it can be prevented in most cases with the medication called immunoglobulin (RhIg).
What blood types can't have babies together? ›
When a mother-to-be and father-to-be are not both positive or negative for Rh factor, it's called Rh incompatibility. For example: If a woman who is Rh negative and a man who is Rh positive conceive a baby, the fetus may have Rh-positive blood, inherited from the father.
What 2 blood types are not compatible for pregnancy? ›Rh incompatibility occurs when a mother has Rh-negative blood and the baby has Rh-positive blood. The mother's body will produce an auto-immune response that attacks the fetus or newborn's blood cells as if they were a bacterial or viral invader.
Is O negative and Rh negative the same? ›Blood is further classified as being either "Rh positive" (meaning it has Rh factor) or "Rh negative" (without Rh factor). So, there are eight possible blood types: O negative. This blood type doesn't have A or B markers, and it doesn't have Rh factor.
Is Rh negative the golden blood type? ›Whilst “golden blood” is still part of the Rh system, it is the rarest known type. It is Rh-null: 61 Rh antigens are absent in it. If you're Rh negative, you still have some Rh proteins but you have more missing than you have present. If you're Rh-null, you have none of these antigens at all.
Does O positive blood have Rh factor? ›O positive.
This blood type doesn't have A or B markers, but it does have Rh factor. O positive blood is one of the two most common blood types (the other is A positive).
