Goodpasture's syndrome is now generally held to be an immunological disease where antibody is formed to the glomerular basement membrane, and where the alveolar damage is secondary to the production of this antibody. The trend is now increas- ingly to reserve the label 'Goodpas- ture's syndrome' for those cases where pulmonary hemorrhage and subacute glomerulonephritis co-exist, and where it is possible to demonstrate linear deposition of IgG along the basement membrane of the glomerulus using immunofluorescent technique.
