A waste product of the kidneys. Increased levels of BUN in the blood may indicate early kidney damage.

2. Blood urea nitrogen (BUN)
This is an indicator of glomerular filtration rate. However, because it is dependent upon the protein intake in the diet and renal function, it is an insensitive indicator. At least 50 % of the kidney substance must be destroyed before BUN is elevated. (Normal range: 3 - 7 mmol/L)
