Test Details
Methodology
Multiplex flow immunoassay
Result Turnaround Time
2 - 4 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Use
Anti-GBM antibodies (glomerular basal membrane; Goodpasture Antigen) are important for the diagnosis of glomerulonephritis, which may be accompanied by pulmonary hemorrhage (Goodpasture pulmo-renal Syndrome). Due to clinical symptoms similar with systemic vasculitis, it is appropriate to concurrently carry out tests for anti-GBM and antineutrophil cytoplasmic antibodies (ANCA).
