UUN is determined from 24-hour urine collection. Along with UUN, values for BUN, protein content of diet, enteral or parenteral nutrition, and notable outputs other than urine (gastric residual, fistula output, drainages) are needed to calculate nitrogen balance.Nitrogen Balance = Protein intake/6.25- (UN + 4*) * For average loss via sweat and feces.

Feb 28, 2018 · A common test for urea nitrogen is the blood urea nitrogen test, better known as BUN.This article refers to the urine urea nitrogen test, which is performed using a urine sample.

Accurate nitrogen balance studies are helpful in monitoring protein utilization and determining appropriate nutrition support regimens in the critically ill. Urinary urea nitrogen (UUN) is commonly used instead of total urea nitrogen (TUN) when calculating nitrogen balance, because it is generally less expensive and more readily available. UUN is thought to comprise 80 to 90% of …

Objective: We investigated the accuracy of methods to estimate total urinary nitrogen (TUN) excretion from urinary urea nitrogen (UUN) excretion for patients who have multiple trauma and receive specialized nutritional support. Methods: Fifty-five critically ill, adult patients who had multiple trauma and were receiving specialized nutritional support were evaluated.

The validity of the urinary urea nitrogen (UUN) estimate of total urinary nitrogen (TUN) was tested in patients who required iv nutrition. UUN and TUN were determined in 120 urine collections from ten preoperative, 13 postoperative, and 11 stressed patients. The …

Nitrogen balance has historically been estimated by using urinary urea nitrogen (UUN) multiplied by a factor of 1.25 to account for nonurea nitrogen present in the urine. Recently, the reliability of UUN as an estimate of nitrogen losses has been questioned and the …
