Rh sensitization can occur during pregnancy if you are Rh-negative and pregnant with a developing baby (fetus) who has Rh-positive blood. Problems with the Rh factor happen when the mother's Rh factor is negative and the baby's is positive. That can happen if some of the baby's blood mixes with the mother’s blood – for instance, following minor injuries to the placenta or umbilical cord during birth. Rh-positive blood does have this marker. A type III hypersensitivity reaction will occur building up in the baby's organs. Typically nothing happens.

One of those tests will determine whether you have the Rhesus protein; in other words, whether you are Rh-positive or Rh-negative. Therefore, a person may have a Rh + blood type and can still have an Rh - gene (See the chart below). Since more people are Rh positive than Rh negative, it is likely that an Rh-negative mother could be carrying a baby who is Rh positive, creating the risk for hemolytic disease of a newborn (HDN) in future pregnancies, essentially destroying that baby’s red blood cells. Problems can arise when the fetus’s blood has the Rh factor and the mother’s blood does not. There can be a problem if a mother and baby have a different blood type and Rh factor. HDN most frequently occurs when an Rh negative mother has a baby with an Rh positive father.
