Blood Urea Nitrogen Test
BLOOD UREA NITROGEN TEST DEFINITIONA BUN test (also known as a blood urea nitrogen test) divulges the important data and info about how healthy the liver and kidneys are and how well they're functioning. This test basically measures the levels of urea nitrogen in your blood.
BLOOD UREA NITROGEN TEST PURPOSEIf your doctor believes you have kidney damage or if the organ's function needs to be analyzed, then you may be tasked to take a BUN test. Alternatively, a BUN test can also assist in determining the effectiveness of hemodialysis or peritoneal dialysis treatment in case you're undergoing either treatment.
BLOOD UREA NITROGEN TEST RISKSYou may become infected, lightheaded, and faint or you may bleed excessively (thanks to a blood condition or by taking anticoagulant drugs) by having your blood drawn depending on the circumstances.

BLOOD UREA NITROGEN TEST PREPARATION REQUIREDBecause the BUN test is your typical blood test, you don't need to undergo any special preparation. You just need to have your blood drawn and endure pain that will last a couple of hours at most. You can drink or eat anything prior to the test without negatively affecting the BUN test's outcome.
BLOOD UREA NITROGEN TEST PROCEDUREThe attending physician, his nurse, or a technician will stick a needle into your vein in order to draw a blood sample from you, which will be sent to a lab to check your urea nitrogen levels). You can return to your normal activities afterwards.
BLOOD UREA NITROGEN TEST COMPLICATIONSThe complications linked with this blood test (or any blood-drawing test) are the accumulation of blood under your skin (hematoma), lightheadedness or fainting, infection (this is always something you risk whenever undergoing a procedure involving skin penetration).
BLOOD UREA NITROGEN TEST SIDE EFFECTSPain and throbbing for a short period of time... around a couple of hours or more... is a common side effect of putting a needle on a vein of your arm and drawing blood from it. If you experience continued, persistent pain long after the BUN test, consult your doctor immediately.
BLOOD UREA NITROGEN TEST RESULTSDepending on what your doctor is looking for or suspecting, if the BUN test shows that your urea nitrogen levels are higher than normal, it could mean that you have poor circulation, inadequate fluid intake, high protein intake, or a sign that your kidneys aren't working the way they should. The normal range of blood urea nitrogen is 8 to 24 milligrams per deciliter (ml/dL) for adult men and 6 to 21 mg/dL for adult women.
