Web23. sep 2024 · Posted January 17, 2024. Under routine circumstances, we do not prepare an eluate from positive DAT cells from a neonate because identity of the antibody can be determined from the mother's sample. Of course, if a neonate with a Positive DAT arrived without a mother, no maternal sample, or from a Group AB mother with a Negative … WebIf the DAT is positive with the anti-IgG reagent then an elution should be performed. Elution Elution is a procedure that allows for the uncoupling (elution) of bound antibodies from sensitized RBCs. These now unbound (eluted) antibodies are referred to as the eluate.
