CVID: Aka combined variable immunodeficiency. This test is done because you have recurrent sinusitis, bronchitis or pneumonia & screening tests for weak immune system - CBC & diff, quantitative immunoglobulins, ch50- are ok. A 2nd low test means you don't make adequate antibodies against some bacteria that infect the respiratory tract. Antibiotics & gamma globulin injections will help you.
