A product of metabolism that is excreted in the urine. It is measured in the blood as an indirect measure of how well the kidney is functioning. Increased BUN levels in the blood may indicate early kidney damage, meaning the kidneys aren't effectively excreting BUN.
A waste product in the blood that comes from the breakdown of food protein. The kidneys filter blood to remove urea. As kidney function decreases, the BUN level increases.
The term BUN refers to the substance urea, which is the major breakdown product of protein metabolism, and is ordinarily removed by the kidneys. During kidney failure, ure accumulates in proportion to the degree of kidney failure and to the amount of protein breakdown. The symptoms of uremia correspond roughly to the amount of urea in the blood stream.
A measure of the nitrogenous waste products circulating in the blood; elevated levels are usually indicative of kidney malfunction.
Byproduct of protein metabolism that is normally filtered out of the blood and found in the urine. Elevated levels in the blood can indicate decreased kidney function.
a measure of blood level of urea, the end product of protein metabolism
the amount of nitrogen associated with urea in the blood. High values are associated with dehydration and compromised kidney function.
this blood test is an indirect measure of kidney function
a measurement of urea in the blood. An elevated Bun may mean the kidneys are not working properly.
Abbreviated BUN. A measure primarily of the urea level in blood. Urea is cleared by the kidney. Diseases that compromise the function of the kidney frequently lead to an increased BUN.
A waste product of the kidneys. Increased levels of BUN in the blood may indicate early kidney damage.
A byproduct of protein breakdown in the body.
A blood test that helps measure kidney function.
The blood urea nitrogen (BUN) test is a measure of the amount of nitrogen in the blood that comes from urea. Urea is a substance secreted by the liver, and removed from the blood by the kidneys.
