Fetal Blood Type Screening Results & Next Steps

Fetal RHD screening uses a blood sample from you to predict your baby’s RhD status. Results help determine whether you need RhD Immune Globulin (RhIG) during pregnancy.

Allo-FBGG is offered when a pregnant person has red blood cell antibodies (anti-D, anti-C, anti-c, anti-E and/or anti-K) that may cause hemolytic disease of the fetus and newborn (HDFN). The result predicts whether your baby has the blood group antigen that your antibody can react to.
