Decreased BUN may be caused by anabolic steroids, diminished protein. Blood urea was elevated 2- to 3-fold in rabbits made anuric by ligation of ureters (Adjarov et al., 1976). Spontaneous or induced tumors affecting kidney function elevated BUN levels (Fox, 1989). Healthy kidneys should remove the BUN and leave only a small amount in the blood. Blood urea values are 2.14 times greater than BUN (urea/2.14 urea nitrogen). Your liver breaks down the proteins you eat and produces urea nitrogen, which is released into your blood.

The normal range of blood urea nitrogen (BUN) is between 7 and 20 mg/dL or 2.5 and 7.1 mmol/L. The normal range of blood urea nitrogen (BUN) is between 7 and 20 mg/dL or 2.5 and 7.1 mmol/L. There is no definite value of BUN that would diagnose kidney failure. Overhydration can also cause low BUN levels. Blood urea nitrogen (BUN) is one of the parameters used to ascertain kidney function. Low protein can cause fatigue, poor muscle tone, poor concentration, and low immunity. Increase your Blood urea nitrogen (BUN) by 2 mg/dL to be within normal range.īecause BUN is produced when your body breaks down protein, a low-protein diet can cause low BUN levels.
