Q

(Loss or Destruction Anemia - Hemolytic anemias) How does the hemolytic disease of newborns work?

A

An Rh negative mother has a baby with Rh positive father, where the1st baby has separate blood circulation & during delivery the blood mixes & the mother will develop antibodies against future Rh-positive babies.
