A female whose blood group is `AB^(-)` got conceived and later it is diagnoised that her foetus possess `B^(+)` What measures would be taken to prevent the focus from Hae molytic disease of New born (HDN

Explanation

If the mother is Rh negative and focus is Rh positive , anti Dantibodies should be administered to the mother at `28^(th) and 34^(th)` week of gestation as a prophylactic measure . If the Rh negative mother delievers Rh positive child then D antibodies hould be administered to the mother soon after delievery . This develops passive immunity and prevents the formatin of anti D antibidies in the mothers blood by destroying the Rh foetal RBC before the mother.s immune system is sensitized . This has to be done whenever the woman attains pregnancy .
