What kind of conditions does Rh isoimmunization develops in a pregnant clien?

Rh-positive fetal blood crosses into maternal blood, stimulating maternal antibodies.

Rh isoimmunization occurs when Rh-positive fetal blood cells cross into the maternal circulation and stimulate maternal antibody production. In subsequent pregnancies with Rh-positive fetuses, maternal antibodies may cross back into the fetal circulation and destroy the fetal blood cells.
