title: IgG antibody level to mycobacterial glycoprotein in pulmonary tuberculosis by ELISA.
abstract: Sera from patients with active pulmonary tuberculosis and sera from appropriate control individuals were assayed for IgG, IgA and IgM antibodies against glycoprotein from tubercle bacilli by an enzyme-linked immunosorbent assay. The mean antibody levels in IgG and IgA were significantly higher in the tuberculosis patients than in the controls. By measuring IgG antibody, this assay may provide a diagnostic tool to distinguish patients with active pulmonary tuberculosis from patients with other pulmonary disease.
