   The blood urea nitrogen (BUN) test is a measure of the amount of nitrogen in the blood that comes from urea. It is used as a marker of renal function , though it is inferior to other markers such as creatinine because blood urea levels are influenced by other factors such as diet, dehydration, [ 35 ] and liver function.
