What is the full form BUN?

BUN stands for "Blood Urea Nitrogen".

It is a blood test that is done in order to know details about the kidney as well as liver functioning. The test is done to measure the amount or count of blood urea nitrogen.

Let’s dig in to understand the importance of this test:

• Liver secrets ammonia which is filled with nitrogen. This fluid helps break down protein with the aid of the body cell.
• The nitrogen so formed then links itself to the other elements for example Carbon, Hydrogen, and Oxygen in order to produce Urea. Which is actually a waste product.
• The urea so formed then travels through the liver to kidneys by the means of a common passage that is the bloodstream.
• The healthy kidney is able to properly filter the urea removing the other waste products from the blood.
• Then the waste product is thrown out of the body by the means of urine.

The test done is able to differentiate the levels of the urea getting produced in the body. The higher the level of nitrogen than normal, the higher risk of the damaged liver and kidney. This damage signifies that the kidney or the liver might not be working properly.
