title: Transplacental passage of anti-s antibody without haemolysis.
abstract: The production of anti-s antibodies during pregnancy is a rare event and usually causes haemolysis of fetal red cells. A case is presented where an IgG anti-s antibody crossed the placenta, but did not produce any evidence of haemolysis.
