+What is Rh+?

- Foetus id Rh+
- Mother is Rh-
- during delivery placental tissue breaks down which results in mixing of blood between foetus and mother
- So foetus Rh+ blood enter mother blood circulation
- as she is Rh-, the Rh+ d antigen is foreign
- so it leads to immune response producing antibodies d
(anti Rh+ antibodies) - These antibodies go into foetus, and attach to foetal RBC
- lead to haemolysis : break down of RBC
- foetus dies!
