Which antibody can cross the placenta?

Understand the Problem

The question is asking about which type of antibody is capable of crossing the placenta from the mother to the fetus during pregnancy. This typically involves understanding the function of different immunoglobulin classes.

More Information

IgG is essential for providing the fetus with immunity against infections during pregnancy. It is transferred across the placenta through a process mediated by the neonatal Fc receptor (FcRn).

Tips

A common mistake is to confuse IgG with other immunoglobulins like IgA, IgM, or IgE, which do not significantly cross the placenta.
