The urea nitrogen appearance, U, equals the urine urea nitrogen + the non urea nitrogen (weight in kg X 0.031 g nitrogen/kg/day).
Calculated Protein Intake is urine nitrogen excreted in grams/day + (weight in kilograms X 0.031 g nitrogen/kg/day) multiplied by 6.25. A 70 kg person with a UUN of 5 grams would have an estimated protein intake of 44.8 grams. Feel free to add your own values.
Calculated Protein Inake is ??? grams.
