Overview
Laboratory findings consistent with the diagnosis of Goodpasture syndrome include presence of auto-antibodies such as anti-glomerular basement membrane antibodies.Other findings associated with pulmonary and renal injury include elevated blood urea nitrogen, low-grade proteinuria, gross or microscopic hematuria, and red cell casts.
Laboratory Findings
Laboratory findings consistent with the diagnosis of Goodpasture syndrome include presence of auto-antibodies such as anti-glomerular basement membrane antibodies.[1][2][3]
- Other findings associated with pulmonary and renal injury include elevated blood urea nitrogen, low-grade proteinuria, gross or microscopic hematuria, and red cell casts.
- If laboratory test cannot detect the presence of anti-glomerular basement membrane antibodies, other tests such as anti-neutrophil cytoplasmic antibodies should be done to determine and rule out the presence of ANCA associated vasculitis.[4]
- Routine laboratory test that may be ordered to help in identifying the cause are:
- Complete blood count (leukocytosis and anemia)
- Renal function test (BUN, S. creatinine )
- Urinalysis for proteinuria, hematuria, and red cell casts
- ESR and CRP
