A Blood Urea Nitrogen (BUN) test reveals vital informations about the functioning of kidney and liver. A BUN test informs that your kidney or liver may not working properly by assessing whether the urea nitrogen levels are higher than normal. It also used to evaluate a person’s general health status.
A BUN Test is required if :
You have a kidney damage,
To evaluate your Kidneys’ function
To assess the effectiveness of dialysis treatment if one receive hemodialysis or peritoneal dialysis.
Though, an abnormal BUN test result alone doesn’t confirm, it can give hints of a possible liver damage, urinary tract obstruction, congestive heart failure or gastrointestinal bleeding.
How BUN rises in blood?
Urea is a byproduct formed in the liver when protein is metabolised.Urea is released by the liver into the blood and is carried to the kidneys, where it is filtered out of the blood and released into the urine. Since this is an ongoing process, there is usually a small but stable amount of urea nitrogen developed in the blood. However, when the kidneys cannot filter wastes out of the blood due to disease or damage, then the level of urea in the blood will rise.
