Hypogammaglobulinemia

Hypogammaglobulinemia refers to a condition where the concentration of some or all types of serum immunoglobulins is lower than normal. Normally, the human body has various types of immunoglobulins. If one, two, or all types of immunoglobulins, such as IgG, IgA, and IgM, are deficient, it can be termed hypogammaglobulinemia. It is primarily observed in infants and young children.
