What's BUN?: BUN stands for blood urea nitrogen. Urea nitrogen is what forms when protein breaks down and it not used by itself to identify patients with kidney disease. BUN is elevated in cases of dehydration as well as kidney disease. Serum creatinine (C) is a better determinant of kidney function. If the BUN C ratio is > 20, the patient may be dehydrated. The normal range of B is 7-20 mg/dl.
