In normal adult serum, the approximate percentage composition of IgG with respect to its subclasses is IgG1:65percent, Ig2:23percent, IgG3:6percent, and IgG4:6percent. Abnormal levels of one or more subclasses may be associated with autoimmune, anaphylatic and gut diseases, as well as with recurrent infection.
