[Studies of immunoglobulins G in newborn infants, using the immunodiffusion method].
Immunoglobulins G (IgG) were determined in the neonate using immunodiffusion in Hyland Travenol agar gel. IgG values were tested in the umbilical cord and perpheral blood, establishing their relationship with various parameters. Hypogammaglobulinemia does not appear to be so rare in the neonate (4.91%).
