KIDNEY BIOPSY LIGHT MICROSCOPY AND DIF

What this test checks

Examines kidney tissue under multiple microscopy techniques — including light microscopy and immunofluorescence — to identify the exact type of kidney disease affecting you.

Why do people get this test?

Many kidney diseases look similar on standard tests but require different treatments. This comprehensive biopsy analysis pinpoints the exact diagnosis so your specialist can choose the most effective therapy.

When you should consider this test

• When kidney function tests are abnormal and the cause is unclear
• When protein or blood is found in the urine and standard tests don't explain why
• Before starting immunosuppressive therapy for kidney disease

How to prepare

Your doctor will give specific instructions before the biopsy procedure. Usually involves lying still; a small tissue sample is taken with a needle under ultrasound guidance.
