Question

Quizplus · Accepted Answer

Passive immunity provides temporary protection to the baby based on the transfer of maternal antibodies. Maternal hormones would not lead to a clinical diagnosis of fetal anemia. These blood types and Rh factors are the same; therefore, no antibodies will be created. In this situation, an Rh-negative mother and Rh-positive baby will result in stimulation of antibodies that will stimulate a reaction leading to hemolysis.
