Where 60 represents MW of urea and 14*2 MW of urea nitrogen. Elsewhere, the concentration of urea is reported in SI unit as mmol/L, which is generally depending on the lab.ī U N m g / d L BUN (Blood Urea Nitrogen) Chemistry study of blood serum to measure the level of urea in the blood, a sign of impaired kidney function or urinary obstruction. If your kidneys are not working well, the urea nitrogen will stay in the blood. Normal range may vary somewhat according to the brand of laboratory assay materials used. OTC deficiency is also accompanied by hyperammonemia and high orotic acid levels.īUN (urea-N) is mg/dL in the United States, Mexico, Italy, Austria, and Germany. Reference values have not been established for patients who are <12 months of age. What level of BUN indicates kidney failure. Women often have a lower creatinine level.

Estatic analysis of these data showed the average of 71.36 mg/dl. A normal result is 0.7 to 1.3 mg/dL (61.9 to 114.9 mol/L) for men and 0.6 to 1.1 mg/dL (53 to 97.2 mol/L) for women. Reference ranges for blood tests, comparing urea (yellow at right) to other blood constituentsĪnother rare cause of a decreased BUN is ornithine transcarbamylase deficiency, which is a genetic disorder inherited in an X-linked recessive pattern. The estimated normal range of BUN was 14-23 mg/dl both in male and female elderly subjects, and that of Cr was 0.9-1.3 mg/dl in male and was 0.7-1.1 mg/dl in. The value of BUN in male cats was between 50.92 mg/dl to 91/8 mg/dl.
