Test Details

The Blood Urea Nitrogen (BUN) Serum test measures the concentration of urea nitrogen in the bloodstream. Urea nitrogen is a waste product produced during the breakdown of proteins in the body. This test is often used to assess kidney function and overall metabolic health.

Blood Sample: A healthcare provider will collect a blood sample, typically from a vein in your arm, using a needle and syringe or a specialized blood collection tube.

Laboratory Analysis: The blood sample is sent to a laboratory for analysis. There, the concentration of BUN is quantified.

Fasting is not usually required for the Blood Urea Nitrogen (BUN) Serum test. You can typically eat and drink normally before the test.

You may feel a brief pinch or discomfort when the needle is inserted to draw the blood sample. Afterward, there might be some mild bruising or soreness at the site, but this is usually temporary

Normal results for the Blood Urea Nitrogen (BUN) Serum test vary depending on the laboratory and measurement units used. Typically, BUN levels fall within a specific reference range

Kidney dysfunction: Elevated BUN levels may suggest impaired kidney function, which can be caused by various kidney conditions.

Dehydration: In some cases, high BUN levels can be associated with dehydration, as less water in the body can lead to higher concentrations of urea nitrogen.

Other medical conditions: Abnormal BUN levels can also be caused by conditions like congestive heart failure, gastrointestinal bleeding, or certain medications.

The Blood Urea Nitrogen (BUN) Serum test is a routine blood test and is generally safe. Risks are minimal and may include:

Mild bruising at the blood sample site.

Rarely, fainting or lightheadedness during or after the blood draw.
