Previously it was seen and thought that ABO
incompatibility protects against pregnancy
induced Rh hincompatibility.But there were some reports that it is always not so.

We,the Neonatologists do not see the bad neonatal naundice cases,hydrops from RH incompatibility.In fact exchange transfusion of blood in newborns has dramatically reduced now!thanks to innovations.
