Normal BUN levels differ with age and gender. A healthy male adult must have BUN levels from 8 to 24 mg/dL, while a healthy female adult should have it from 6 to 21mg/dL. The normal BUN levels for children fall between 5 and 18 mg/dL.Meanwhile, the healthy BUN level for pregnant women is from 5 to 12 mg/dL. The normal BUN levels for children and women are relatively low due to their bodiesâ ability to split up protein molecules.he normal BUN levels for children fall between 5 and 18 mg/dL. Meanwhile, the healthy BUN level for pregnant women is from 5 to 12 mg/dL.
Urea is found dissolved in blood and is excreted by the renal tubules. In addition, a small amount of urea is also excreted in sweat. Therefore, the BUN level may reflect functioning of the liver and/or kidneys. In the United States, blood urea nitrogen (BUN) is measured in mg/dL.To convert BUN to a concentration in mmol/L (SI units), multiply by 0.357 ([10 dL/1 L]/[28 mg of N/mmol of urea] = 0.357).n addition, a small amount of urea is also excreted in sweat. Therefore, the BUN level may reflect functioning of the liver and/or kidneys. The reference range of the BUN level is 3-20 mg/dL. Individual laboratories may have different reference ranges, since the procedure may vary.
