The theory claims that blood types are an important indicator of a person’s personality. In Japan, there’s a blood type personality theory known as ketsueki-gata. People with the blood type AB- represent about 0.6% of the adult population.ĭoes blood type affect personality compatibility?.People with the blood type AB+ represent about 3.4% of the adult population.People with the blood type B- represent about 1.5% of the adult population.People with the blood type B+ represent about 8.5% of the adult population.People with the blood type A- represent about 6.3% of the adult population.People with the blood type A+ represent about 35.7% of the adult population.People with the blood type O- represent about 6.6% of the adult population.People with the blood type O+ represent about 37.4% of the adult population.According to the Stanford School of Medicine, in the United States: How common are different blood types?ĭepending on your blood type, it might be easier or more difficult to find a potential partner with a compatible blood type. So, if you want to be in a position to donate blood to your spouse, make sure you and your future spouse have compatible blood types. Rh+ or Rh- blood can be given to those who are Rh+, but if you are Rh-, you can only receive Rh- blood. If you have type B blood, you can receive type B or type O red blood cells.If you have type A blood, you can receive type A or type O red blood cells.If you have type O- blood, you are a universal donor and can donate red blood cells to anyone.If you have type AB+ blood, you are a universal recipient and can receive red blood cells from all donors.A transfusion of the wrong type of blood product can result in a potentially fatal toxic reaction.īeing able to supply needed blood for a partner with a medical issue might not be a deal breaker for most couples, but it could be a nice perk in the event of an emergency. People without compatible blood types cannot donate blood to each other. Rh immune globulin contains Rh IgG antibody, so your body does not react to your baby’s Rh positive cells as if they were a foreign substance, and your body will not produce its own Rh antibodies.Ĭompatible blood types could be useful if you or your partner need a blood transfusion. If Rh incompatibility has been diagnosed, your doctor will most likely recommend Rh immune globulin (RhoGAM) in your seventh month of pregnancy, and then again within 72 hours after delivery if your baby’s blood type is confirmed as Rh positive upon delivery. If this occurs, your baby might need a red blood cell transfusion either during your pregnancy or immediately after delivery. If there was an Rh incompatibility in a first pregnancy, and there’s an Rh incompatibility in second and other future pregnancies, these maternal antibodies can damage the baby’s red blood cells. But they can cause issues if you have a subsequent pregnancy and are carrying another child that is Rh+. These antibodies will not cause problems to an Rh+ baby during the first pregnancy.
If there’s an Rh incompatibility and this happens, your body might produce Rh antibodies against Rh factor. If your doctor identifies a potential for Rh incompatibility, your pregnancy will be monitored closely for any related issues and may need extra care.Īlthough your blood and your baby’s blood typically do not mix during pregnancy, a minimal amount of your baby’s blood and your blood could come in contact with each other during delivery. That would indicate that your baby is Rh+. If you are Rh-, your doctor will test your blood again later in your pregnancy to see if you have formed antibodies against Rh factor. The mother’s body might form antibodies to attack the baby’s Rh+ red blood cells.Īt your first prenatal visit, your doctor will suggest a blood type and Rh factor screening. Blood cells from an Rh+ baby crossing its Rh- mother’s bloodstream might trigger an immune response. Rh factor can be a concern if the biological mother is Rh- and the baby is Rh+. The most common type is Rh positive.īeing Rh positive or negative typically does not affect your health, but it could affect your pregnancy. Rh factor is an inherited protein, so being Rh negative (-) or Rh positive (+) is determined by your parents. How does blood compatibility affect pregnancy?Ĭompatibility in blood group is only a concern for couples if a pregnancy is involved where both partners are the biological parents.
