What is BUN?

BUN test is a short form of the Blood Urea Nitrogen test. When our body breaks the protein that we consume through foods, our liver produces urea nitrogen as a waste product.

When we talk about the functionality of kidneys, they are responsible for eliminating waste products through urination.

BUN is removed by the kidneys through urine. If our kidneys are not healthy, BUN will not be adequately removed from the body and mixed up with blood.

A BUN test is performed to check the amount of waste product present in your blood. BUN Lab Value means a normal range of BUN levels in our blood. If the amount of BUN in our blood is high, there might be a problem with your liver or kidneys.
