Kidney biopsy section from Patient 1 showing (a) pauci-immune focal necrotising glomerulonephritis (H and E, × 400) and (b) negative immunofluorescence for IgG (× 400); (c) A positive control showing linear IgG staining at identical exposure; (d) Indirect immunofluorescence staining of patient sera on primate kidney; (e) positive control indirect immunofluorescence and (f) negative control indirect immunofluorescence. Positive anti-glomerular basement membrane staining for IgG in a linear fashion was seen using the patient’s serum (× 400)
