ARCE HERNANDEZ, Ada Amalia  y  VILLAESCUSA BLANCO, Rinaldo. IgG subclasses in several diseases: clinical significance. Rev Cubana Hematol Inmunol Hemoter [online]. 2004, vol.20, n.3, pp. 0-0. ISSN 1561-2996.

IgG subclass deficiencies represent possible disturbances of immune responses, although several studies have shown low concentrations of IgG subclasses in asymptomatic individuals. A number of diseases associated with increased or decreased levels of IgG subclasses as well as indications for their measurement were described in this paper.
