The Rh factor test is done during pregnancy to identify a woman's Rh factor. In some cases, the baby's father might need an Rh factor test, too. During pregnancy, problems can occur if you're Rh negative and the baby you're carrying is Rh positive. Usually, your blood does not mix with your baby's blood during pregnancy.
This immune system response is called Rh sensitization. Rh sensitization can occur during pregnancy if you are Rh-negative and pregnant with a developing baby (fetus) who has Rh-positive blood. In most cases, your blood will not mix with your baby's blood until delivery.
