Current Question (ID: 14446)

Question:

Erythroblastosis foetalis occurs when a factor from mother passes into the foetus through the placenta. The factor is

Options:

1. Rh antigen
2. Rh antibodies
3. Agglutinins
4. ABO antibodies

Solution:

Erythroblastosis foetalis is a hemolytic disease that occurs in newborns due to Rh incompatibility between the mother and the foetus. If the mother is Rh-negative and the foetus is Rh-positive, there is a risk that the mother's immune system will produce antibodies against the Rh factor. These antibodies can cross the placenta and attack the foetus's red blood cells, causing hemolysis and other complications. This condition can be prevented by administering Rh immunoglobulin to the mother during pregnancy.
