Rhesus (Rh) Factor

Rhesus Rh Factor

Rhesus, or Rh factor, can help determine if special care is needed during pregnancy. If the mother is Rh factor negative and the father is Rh factor positive, then there is a potential for the fetus to develop hemolytic anemia (low iron due to immune attack). This said, it is important for both mother and father to be tested.

You should bring your Rh factor test results to your primary care physician.
