What is the test?
A kidney biopsy is a procedure to obtain a sample of your kidney tissue so that it can be examined under a microscope. A kidney biopsy is useful in patients with kidneys that are not functioning properly, to determine the cause of the problem and the most appropriate treatment.
How do I prepare for the test?
You will need to sign a consent form giving your doctor permission to perform this test. Tell your doctor if you have ever had an allergic reaction to lidocaine or the numbing medicine used at the dentist's office.
