Defining normal IgG changes throughout pregnancy

[摘要] Immunoglobulin G (IgG) is the major serum immunoglobulin, accounting for roughly 75% of all immunoglobulin. IgG is the only class of immunoglobulin that crosses the placenta and it serves as the main immunologic barrier between the fetus and external environments.There has not been a clear consensus on what the normal values of IgG are throughout pregnancy.The aim of this study is to measure serum immunoglobulin G in each trimester of the pregnant female to determine a normal IgG profile throughout all trimesters in normal pregnancy.
