Why do people get a blood urea nitrogen (BUN) test?

ANSWER

Your doctor may order a BUN test as part of a routine checkup. It may be one of several blood tests that you get.

If you have a kidney condition, the test is a way to check what your BUN levels are before you start a medication or treatment. It’s also standard for a BUN test to be given when you’re in the hospital for certain conditions.

If your doctor suspects you may be getting kidney problems, she may order the BUN test.
