A member asked:

What does quantitative igg subclass measurement blood test show?

A doctor has provided 1 answer

IgG subclasses: There are several classes of immunoglobulins like IgA, IgM, and IgE. IgG also has subclasses that we test for. A subclass deficiency can be an explanation for susceptibility to certain types of infections. An Allergist/Immunologist can put the results in perspective for you in the context of your history.
