Managing transfusion of female children and women of childbearing age involves managing risks not present in other patient groups. Of key significance is accurate RhD typing to determine risk for anti-D.
- Between 1% and 4% of individuals have altered D antigens
- “Partial D” phenotypes or "Weak D" phenotypes
- Patient is RhD positive but may be at risk for anti-D
- Serology cannot distinguish these. RhD genotyping can determine:
- appropriate transfusion (Rh neg or Rh pos)
- candidates for Rh immune globin
