Complement Tests are not typically used as the primary diagnostic tool for Goodpasture's syndrome, a rare autoimmune disorder that affects the lungs and kidneys. Goodpasture's syndrome is primarily diagnosed through clinical evaluation, including symptoms, specific blood tests for anti-glomerular basement membrane (anti-GBM) antibodies, and, in some cases, kidney biopsies. However, Complement Tests may provide supplementary information about complement activity in some cases, contributing to disease management.
