Urea Nitrogen, 24 Hr details
What Urea Nitrogen, 24 Hr shows
Urea is the main waste product made when your body breaks down protein, and most of it is removed by the kidneys in urine. This test measures the total urea nitrogen in all the urine you pass over 24 hours. It is mainly used to estimate how much protein you are eating and breaking down, and to assess nitrogen balance, for example during illness or nutritional support. A higher result can reflect a high-protein diet or increased protein breakdown. A lower result can reflect low protein intake or reduced kidney function. An incomplete collection affects the result, so it is interpreted with your diet, health and blood tests.
