Rh-ve mother
Her 1st Rh +ve child
Anti Rh antibody produced in mother
Contact of blood at birth
Her subsequent child will be acted on by the antibody
1. If the mother is Rh-ve and her first child is
Rh+ve.
Would the mother have problem ?
2. If the mother is Rh+ve and her first child is
Rh-ve.
I) Would the mother have problem ?
II) Would her subsequent children have problem ?
