Normal BUN Levels What is the normal level of BUN? 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 bodies’ ability to split up protein molecules. Oftentimes, the BUN test is done together with the Creatinine test to figure out renal problems.

Bright Hub Engineering Before explaining what an azeotrope is, it would be useful to define the process of distillation. The process of distillation relies on the fact that the different components of a mixture will boil and therefore vaporize at different temperatures.This is possible because the various ingredients of the mixture have different boiling points.he process of distillation relies on the fact that the different components of a mixture will boil and therefore vaporize at different temperatures.

BUN-to-creatinine ratio The normal range of urea nitrogen in blood or serum is 5 to 20 mg/dl, or 1.8 to 7.1 mmol urea per liter. The range is wide because of normal variations due to protein intake, endogenous protein catabolism, state of hydration, hepatic urea synthesis, and renal urea excretion.A BUN of 15 mg/dl would represent significantly impaired function for a woman in the thirtieth week of gestation.he range is wide because of normal variations due to protein intake, endogenous protein catabolism, state of hydration, hepatic urea synthesis, and renal urea excretion.

- Blood urea nitrogen (BUN) measures the amount of urea nitrogen in bloodstream. Urea is formed in liver as the end product of protein metabolism and digestion. Urea is transported to the kidneys for excretion. A normal range for blood urea nitrogen is generally 8 to 24 mg/dl for adult males and 6 to 21 mg/dl for females.Generally, a high blood urea nitrogen level means that the kidneys are not performing well, particularly if the result is above 50mg/dl.lood urea nitrogen (BUN) measures the amount of urea nitrogen in bloodstream.

Overview Results of the blood urea nitrogen test are measured in milligrams per deciliter (mg/dL) in the United States and in millimoles per liter (mmol/L) internationally. In general, around 7 to 20 mg/dL (2.5 to 7.1 mmol/L) is considered normal. But normal ranges may vary, depending on the reference range used by the lab, and your age. Ask your doctor to explain your results. Urea nitrogen levels tend to increase with age. Infants have lower levels than other people do, and the range in children varies. Generally, a high blood urea nitrogen level means your kidneys aren't working well.

Blood urea nitrogen The BUN is roughly one-half of the blood urea (R). Normal human adult blood should contain between 5 to 20 mg of urea nitrogen per 100 ml (5–20 mg/dL) of blood, or 1.8 to 7.1 mmol urea per liter (R). To convert from mg/dL of blood urea nitrogen to mmol/L of urea, multiply by 0.357.

What is the normal level of urea in the blood? Confidence votes 162. Normal findings (in mg/dL) are 10 to 20 for adults, 5 to 18 for children and infants, 3 to 12 for newborns, and 21 to 40 for cord blood. In the elderly, the blood urea nitrogen may be slightly higher than the normal adult range. while a maximum limite of a normal range can reach 25 mg/100 ml.n abnormally high blood urea nitrogen (BUN) level may indicate  damage to the kidneys and a decreased ability to properly remove  nitrogenous waste from the blood in your u … rine.

Normal BUN & Creatinine Levels The BUN measures the amount of urea nitrogen in the blood. Urea is formed in the liver as the end product of protein metabolism and digestion. The urea is deposited in the blood and transported to the kidneys for excretion. The BUN serves as an index of the function of the liver and the kidneys.

Blood Urea Nitrogen (BUN) Occasionally, a health practitioner will look at the ratio between a person's BUN and blood creatinine to help determine what is causing these concentrations to be higher than normal. The ratio of BUN to creatinine is usually between 10:1 and 20:1. An increased ratio may be due to a condition that causes a decrease in the flow of blood to the kidneys, such as congestive heart failure or dehydration.

What Is BUN in a Blood Test? A blood urea nitrogen, or BUN, test is used to gauge the amount of nitrogen in the blood of a person. It also helps to understand how well the liver and kidneys are functioning, as stated by the Mayo Clinic. If the urea nitrogen levels are high in the blood, it shows that the kidneys are not functioning properly. A person is advised not to consume a lot of meat or other protein-rich food 24 hours prior the test. A BUN test may be conducted together with a creatinine test.

Useful For Clinicians frequently calculate a convenient relationship, the urea nitrogen/creatinine ratio: serum bun in mg/dL/serum creatinine in mg/dL. For a normal individual on a normal diet, the reference interval for the ratio ranges between 12 and 20, with most individuals being between 12 and 16.

Understanding Blood Work: The Biochemical Profile for Dogs BUN stands for blood urea nitrogen and is the primary end product of protein metabolism. High levels indicate kidney failure or disease, dehydration, shock, high protein diet, certain toxin ingestions, poor circulation to the kidneys and urinary obstruction. Low levels indicate liver disease or starvation.

What is blood urea nitrogen (BUN)? 384,845 Helpful Votes. A. Blood urea nitrogen (BUN) is a product of metabolism that is excreted in the urine. It is measured in the blood as an indirect measure of how well the kidney is functioning. Increased BUN levels in the blood may indicate early kidney damage, meaning the kidneys aren't effectively excreting BUN.

- Updated April 19, 2016. Blood urea nitrogen - BUN - is a blood test performed as a marker of kidney function. It is part of the basic metabolic panel done for health screening. It is also used to monitor the progression of kidney failure. BUN is produced by the breakdown of protein and usually cleared from the blood by the kidneys.
