Ordering Recommendation

Use to determine the genetic etiology of disease in individuals with a suspected or confirmed diagnosis of a primary antibody deficiency (eg, agammaglobulinemia, hyper-IgM syndrome, or common variable immunodeficiency). This test does not analyze B-cell expression or immunoglobulin levels and is not recommended for individuals who have not had previous clinical testing for immunodeficiencies.
