HISTOPATHOLOGY KIDNEY BIOPSY LIGHT MICROSCOPY

What this test checks

Examines kidney tissue under standard light microscopy to identify structural changes in the kidney — used for diagnosing glomerular diseases, tubular injury, and interstitial nephritis.

Why do people get this test?

Light microscopy alone provides essential information about kidney disease patterns, identifying many conditions without the need for additional special stains or immunofluorescence.

When you should consider this test

• When kidney function is declining and the cause needs to be established
• As part of a kidney biopsy work-up (may be combined with immunofluorescence and electron microscopy)
• When investigating proteinuria, haematuria, or nephrotic syndrome

How to prepare

No preparation needed — the kidney biopsy is performed by a nephrologist at the hospital.
