The 16 pages that link to Kidney biopsy, each with the reason it gives.

• Chronic kidney diseaseRelated: It can identify the cause and pattern of damage when blood and urine tests are insufficient.

• Diabetic nephropathyRelated: It can distinguish diabetic lesions from other causes when the presentation is atypical.

• ProteinuriaRelated: Biopsy can identify the disease causing persistent or substantial protein loss.

• Nephrotic syndromeRelated: Biopsy can identify the underlying glomerular disease when clinical features do not suffice.

• Granulomatosis with polyangiitisRelated: It can confirm pauci-immune glomerulonephritis and assess the severity of renal involvement.

• IgA nephropathyRelated: Biopsy establishes the diagnosis by showing IgA-dominant deposits and characterizing lesions.

• Alport syndromeRelated: Biopsy may reveal characteristic basement-membrane changes when genetic testing is unavailable or inconclusive.

• GlomerulonephritisRelated: Biopsy can identify the pattern and severity of glomerular injury.

• NephrologyRelated: It can distinguish diseases that produce similar symptoms or laboratory results.

• Fanconi syndromeRelated: Biopsy can clarify the cause when proximal-tubule injury or light-chain disease is suspected.

• Goodpasture syndromeRelated: Linear antibody staining along glomerular basement membranes supports the diagnosis.

• Atypical hemolytic uremic syndromeRelated: Biopsy can demonstrate thrombotic microangiopathy when clinical findings leave the diagnosis uncertain.

• Focal segmental glomerulosclerosisRelated: Biopsy establishes the lesion and helps distinguish its histologic variants and causes.

• Rapidly progressive glomerulonephritisRelated: Biopsy identifies crescents and helps distinguish the causes of rapidly declining function.

• Membranoproliferative glomerulonephritisRelated: Biopsy establishes the pattern and helps identify the mechanism of injury.
