A kidney biopsy is the removal of a small piece of kidney tissue or cells. A doctor who specializes in tissue diagnosis uses a microscope to look at the tissue for abnormalities.

A kidney biopsy is done to diagnose a disease or medical condition.
A kidney biopsy may be done if you have:
- Blood in the urine
- High levels of protein in the urine
- Low kidney function
- A growth on the kidney
- Kidney infection
- A cyst on the kidney
After the tissue is examined, your doctor can make a diagnosis and provide treatment.
If you had a kidney transplant, this procedure may be done to see if your new kidney is working properly.
