blood urea nitrogen
Kidney waste marker
Blood urea nitrogen is a measure of the nitrogen contained in urea circulating in the bloodstream, used as an indicator of kidney function.
The kidneys filter urea, a waste product of protein metabolism, from the blood; elevated levels suggest the kidneys aren't working efficiently.
Often abbreviated BUN: The doctor ordered a BUN test as part of the routine bloodwork.
