Mrs. RF is a 29-year-old female who has been admitted for delivery of her third child. She has no history of transfusion. History check reveals a group and screen was performed 11 months earlier.
Results from that admission:
- O Rh negative
- Antibody screen: negative by LISS IAT
A group and screen is ordered as a precaution and as a consequence of the difficult delivery of her second child. A healthy infant is delivered and the cord blood is sent to the lab for testing.
- The laboratory SOP for maternal-fetal testing protocol requires an ABO/Rh and DAT on the cord blood.
- A maternal group and screen is performed as ordered.
