What is a CVID?
Common variable immunodeficiency (CVID) is a group of disorders characterized by low levels of a type of protein known as immunoglobulins (Ig). Because of low level of Ig, the immune system cannot make antibodies that fight bacteria, viruses or other toxins in the body.

While in most cases the cause of CVID is unknown, a genetic change has been found in about one-third of cases. [4] This condition is diagnosed based on the symptoms, specific laboratory testings, and exclusion of other disorders. Treatment for CVID includes Ig replacement therapy, which stops the cycle of recurrent infections.
