What is the Rh factor? Why is it important? (2021).Necessary cookies are absolutely essential for the website to function properly.ABO and Rh blood group distribution in Kayseri province, Turkey. 225,000 people who were tested for the virus were involved in the study, with researchers finding that risk was 12 lower for those with O blood type compared to those. The significance of being Rh negative or Rh positive. A study published in late 2020 in Annals of Internal Medicine, revealed that people with type O or Rhnegative blood may be at slightly lower risk from COVID-19.The Rh factor: How it can affect your pregnancy.Pregnancy and birth: What is the benefit of determining the Rh factor before birth?

This reaction can produce a number of symptoms and rapidly progress to shock. Similarly, Rh-negative people who receive an Rh-positive blood transfusion may experience an incompatible transfusion reaction, known as an acute hemolytic transfusion reaction. In severe cases, this may result in a stillbirth. Due to a lower number of RBCs, the fetus may also experience anemia and the enlarging of their organs. When RBCs break down, they release bilirubin, which may cause jaundice. However, without treatment, later pregnancies may be at risk.Īn attack by the anti-D antibodies on the fetal blood cells can result in hemolytic disease of the newborn.

Health problems do not usually occur during an Rh-negative person’s first pregnancy with an Rh-positive fetus, as the body is unlikely to produce enough anti-D antibodies. Some people may refer to this as Rh disease. These antibodies can cross the placenta and attack the fetus’s blood cells. When a person who is Rh-negative is pregnant with an Rh-positive fetus, their body will recognize the Rh-positive blood as foreign and produce anti-D antibodies.

This may occur during pregnancy or if a person accidentally receives incompatible blood during a transfusion. The main complication relating to Rh factors involves those who are Rh-negative encountering Rh-positive blood and producing anti-D antibodies in response. However, it can influence their compatibility with other blood types, affecting the type of blood they can receive. While being Rh-positive is more common, being Rh-negative does not indicate illness, and it does not usually affect a person’s health. The positive or negative sign next to the ABO grouping refers to the Rh status and whether the RhD antigen is present or not. Combining these systems creates the eight most common blood types: People with no A or B antigens on the surface of their RBCs have blood type O. The absence or presence of A or B antigens and Rh factor can help classify blood types. RBCs contain proteins, or antigens, on their surface that allow specialists to determine blood types. Although Rh status can vary among populations, roughly 85% of people in the United States are Rh-positive. People inherit their Rh status from their parents, separate from their ABO blood type. The Rh D antigen is the most immunogenic, meaning that it may provoke an immune response. There are five main Rh antigens on RBCs, of which the most important is the Rh D antigen. The Rh factor is an inherited protein that can be present on the surface of RBCs. Share on Pinterest Yothin Sanchai/EyeEm/Getty Images
