Clinical significance: |
The ABO/Rh is necessary to evaluate newborn’s compatibility with maternal blood and therefore gauge the risk of hemolytic disease of the newborn. The Rh is used to determine if the mother is a candidate for Rh Immune Globulin. The DAT determines if red cells have been coated in vivo with immunoglobulins (IgG only) and is used primarily for investigation of hemolytic disease of the fetus and newborn. | |
