A kidney biopsy is used to identify the nature and extent of kidney damage. The biopsy may be carried out as an outpatient procedure, or you may have to stay in hospital overnight. During the biopsy, a small piece of kidney tissue is removed. This tissue is then sent to a laboratory for microscopic examination. After the biopsy, you will be advised to rest for about 2 hours to minimize the risk of bleeding from the kidney.
