Blood urea nitrogen (BUN) measures the amount of nitrogenous waste (specifically urea) in the blood, which signifies the efficiency of the kidneys in filtering out waste products. Creatinine clearance and urinalysis also evaluate kidney function, but they are not specifically measuring the amount of nitrogenous waste in the blood. Culture and sensitivity is a test used to identify the specific microbe causing an infection and determine the best antibiotic treatment, so it is unrelated to measuring nitrogenous waste levels.
