Antibody screen: An antibody screen will tell if you have antibodies that can affect the fetus. If you have those antibodies that can cross the placenta and affect the fetus, an ultrasound by a high risk obstetrician (maternal fetal medicine doctor) can tell with there are affects such as edema.

Only if you're Rhneg: In order to be at risk, you need to have an rh (rhesus)-negative blood type (ex. A neg, etc.) and a positive antibody screen, which is drawn in the first trimester. In this case, your obstetrician should do frequent antibody titers to assess the risk, and check the father-of-the baby's rh-status. If he's negative, you're not at risk. If he's positive and the titer is high, you need ultrasound eval.

Follow titers: There is a blood test they can do on you every few weeks called titers. They measure your bodies reaction to the baby's blood type. If the titers start going up then they will need to check to see if the baby has developed anemia.
