Treatment for common variable immunodeficiency aims at boosting the body's immune response and preventing or controlling infections. Immune serum, obtained from donated blood, is given as a source of antibodies
Common variable immunodeficiency is an immunodeficiency disorder characterized by a low level of antibodies. Patients with this disease are subject to recurring infections.
With good medical care, people with common variable immunodeficiency usually have a normal life span.
The main diagnostic test that distinguishes common variable immunodeficiency from other immunodeficiency diseases is the low antibody level despite the normal number of B cells. Antibody levels are tested in the serum

B cells with IgG antibodies on their surface are capable of responding to microorganisms. The lack of IgG on the surface of the B cells means that they are not prepared to fight infection.
Patients with this disease have frequent infections, especially those caused by the same microorganism. Recurring infections are an indication that the immune system is not responding normally and developing immunity to reinfection.
The disease itself cannot be prevented, but patients and their families can take precautions to prevent the recurrent infections commonly associated with it. For example, good hygiene and nutrition are important, as is avoiding crowds
The main symptom is recurring infections that tend to be chronic rather than acute. Patients may also develop diarrhea and, as a consequence of the diarrhea, do not absorb food efficiently. This can lead to malnourishment
