It happens when the Rh factors in the mom's and baby's blood don't match. If the Rh negative mother has been sensitized to Rh positive blood, her immune system will make antibodies to attack her baby. When the antibodies enter your baby's bloodstream, they will attack the red blood cells.
Rhesus (Rh) factor is an inherited protein found on the surface of red blood cells. If your blood lacks the protein, you're Rh negative. Rh positive is the most common blood type. Having an Rh negative blood type is not an illness and usually does not affect your health.

Being Rh-negative in and of itself does not cause miscarriage or pregnancy loss. You are only at risk if you have been sensitized. The risk is very small if you have the recommended RhoGAM shots during pregnancy, or after an ectopic pregnancy, pregnancy loss, or induced abortion.
Mother-fetus incompatibility occurs when the mother is Rh- (dd) and her fetus is Rh+ (DD or Dd). Maternal antibodies can cross the placenta and destroy fetal red blood cells. The risk increases with each pregnancy. Rh type mother-fetus incompatibility occurs only when an Rh+ man fathers a child with an Rh- mother.
In general, the rarest blood type is AB-negative and the most common is O-positive. Here's a breakdown of the most rare and common blood types by ethnicity, according to the American Red Cross.
One of the rarest blood types in the world is Rhnull, sometimes referred to as 'golden blood'. People with this blood type have a complete absence of any of the Rh antigens.
It happens when the Rh factors in the mom's and baby's blood don't match. If the Rh negative mother has been sensitized to Rh positive blood, her immune system will make antibodies to attack her baby. When the antibodies enter your baby's bloodstream, they will attack the red blood cells.
If the mother is Rh-negative, her immune system treats Rh-positive fetal cells as if they were a foreign substance. They destroy the baby's circulating red blood cells. When red blood cells are broken down, they make bilirubin. This causes an infant to become yellow (jaundiced).
When the blood from your Rh-positive baby enters your Rh-negative bloodstream, there will be a blood type mismatch. RhoGAM, if given to you at the right time, will prevent your immune system from reacting to your baby's blood. RhoGAM is made from human blood and may carry a risk of transmitting disease-causing agents.
If your baby has Rh-positive blood, you will get another dose of RhoGAM within 72 hours after you give birth. If your baby's blood is Rh negative, you will not need the second RhoGAM shot.
RhoGAM prevents the Rh-negative mother from making antibodies directed against her baby's Rh-positive red blood cells during her pregnancy. While there can be mixing of blood between mom and baby, the dose of antibodies in RhoGAM given to Rh-negative moms has never been shown to harm the fetus.
Special immune globulins, called RhoGAM, are now used to prevent RH incompatibility in mothers who are Rh-negative. If the father of the infant is Rh-positive or if his blood type is not known, the mother is given an injection of RhoGAM during the second trimester.

Being Rh negative means that you do not have Rh proteins on your red blood cells. Fortunately, Rh sensitization is very rare because women who are Rh negative can get a shot that stops their body from making antibodies to Rh-positive blood.
However, when it comes to the Rh blood types, many of us do not fully understand what it means to be positive or negative. In the United States, approximately 85% of the population has an Rh-positive blood type, leaving only 15% with Rh negative.
Of the eight main blood types, people with type O have the lowest risk for heart disease. People with types AB and B are at the greatest risk, which could be a result of higher rates of inflammation for these blood types. A heart-healthy lifestyle is particularly important for people with types AB and B blood.
No it doesn't. Neither of your parents has to have the same blood type as you. For example if one of your parents was AB+ and the other was O+, they could only have A and B kids. In other words, most likely none of their kids would share either parent's blood type.
In areas with a lot of Toxoplasma, being Rh negative might be an advantage. The less severe effects of the parasite may outweigh the effects on pregnancy. Rh negative people may also be resistant to other viruses or parasites that we haven't discovered yet.
Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.
Compatible blood types could be useful if you or your partner need a blood transfusion. People without compatible blood types cannot donate blood to each other. If you have type A blood, you can receive type A or type O red blood cells. If you have type B blood, you can receive type B or type O red blood cells.
Almost always, an individual has the same blood group for life, but very rarely an individual's blood type changes through addition or suppression of an antigen in infection, malignancy, or autoimmune disease. Another more common cause of blood type change is a bone marrow transplant.
Types O negative and O positive are best suited to donate red blood cells. O negative is the universal blood type, meaning that anyone can receive your blood. And O- and O+ blood are both extra special when it comes to traumas where there is no time for blood typing.
People with A blood type are sensitive, cooperative, emotional, passionate and clever. They are very patient, loyal and love peace and thus do not like to get into a fight with anyone. But sometimes these people become overly sensitive.
A person with type A blood receiving a transfusion of type B or AB blood would have an ABO incompatibility reaction. In an ABO incompatibility reaction, your immune system attacks the new blood cells and destroys them. If you have type AB blood, you have both A and B antigens.
ABO Compatibility
A mother and child may also have an ABO blood type incompatibility, which can also cause hemolytic disease of the newborn. However, this incompatibility usually has less serious consequences. It occurs when the mother is type O and the baby is A, B, or AB.
