Interpretation
If the mother is not sensitized to the Rho(D) antigen, is Rho(D) negative, delivers a Rho(D) positive infant, and has a negative DAT test, the mother is a candidate for Rho(D) immune globulin. Although the DAT test can be positive due to ABO attached antibodies, this will not exclude the mother’s candidacy for RhIG immune globulin.
