Pulmonary renal syndrome (PRS) is characterized by rapidly progressive glomerulonephritis (RPGN) and diffuse alveolar hemorrhage secondary to an autoimmune response. The most common causes of PRS in adults are ANCA-associated vasculitis (AAV) and anti-GBM disease. Due to the overlap in clinical presentation, frequency of RPGN, and the need for early diagnosis and treatment, testing for ANCA and anti-GBM is recommended during the differential diagnosis.

Prompt identification of ANCA and anti-GBM antibodies allows for early initiation of treatment and may improve patient outcomes. Antibodies to GBM antigens cause glomerulonephritis, Goodpasture’s syndrome, and, less commonly, pulmonary hemosiderosis. Anti-neutrophil cytoplasmic antibodies occur in various types of autoimmune diseases including renal limited vasculitis (e.g., Wegener’s granulomatosis [WG] or microscopic polyangiitis [MPA]) and pauci-immune necrotizing GN.1 Comprehensive testing, prompt result reporting, and access to more than 150 years of advanced medical knowledge deliver the answers your practice needs to keep care local.
