A kidney biopsy is a test to take a sample (biopsy) of kidney. The doctor puts a long needle through your back (flank) into the kidney. Another doctor will look at the kidney tissue with a microscope to check for problems.
After the test, you will be told to lie down on your back for several hours. After this, you should avoid strenuous activity for about 1 week.
It's normal to feel some soreness in the area of the biopsy for 2 to 3 days. You may have a small amount of bleeding on the bandage after the test. You may notice some blood in your urine after the test. This should go away within 12 to 24 hours. If it doesn't, call your doctor or Health Link at 811.
It can take several days to get the results of the biopsy. The doctor or nurse will discuss the results with you.
