Nitrile rubber Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Nitrile rubber, also known as Buna-N, Perbunan, acrylonitrile butadiene rubber, and NBR, is a synthetic rubber copolymer of acrylonitrile (ACN) and butadiene. Trade names include Nipol, Krynac and Europrene.

- A common blood test, the blood urea nitrogen (BUN) test reveals important information about how well your kidneys and liver are working. A BUN test measures the amount of urea nitrogen that's in your blood. Your liver produces ammonia — which contains nitrogen — after it breaks down proteins used by your body's cells.

Viton vs. Buna: Which seal for your applications? Viton and Buna seals have several very crucial differences that make them especially well suited to certain applications. While both Viton and Buna seals both serve as great sealing options at moderate temperatures, Viton is far superior to Buna for high temperature applications.oth of these sealing options offer an extensive list of diverse applications, and they both serve as excellent general purpose seals. Nevertheless, to optimize your choice in seals be sure to consider the advantages and disadvantages of these two exceptional seals.

BUN-to-creatinine ratio In medicine, the BUN-to-creatinine ratio is the ratio of two serum laboratory values, the blood urea nitrogen (BUN) (mg/dL) and serum creatinine (mg/dL) (Cr).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. A BUN of 15 mg/dl would represent significantly impaired function for a woman in the thirtieth week of gestation.

- 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.

What Does a High BUN Count Mean? BUN is an acronym for blood urea nitrogen, and results can vary depending on an individual's age as well as the lab that processes the test, as explained by Mayo Clinic. Shock, severe burns and some medications, such as certain antibiotics, can also cause higher-than-normal BUN results. Doctors consider a BUN test a standard type of blood test and use it to measure the amount of urea nitrogen in the blood. The liver breaks down proteins in the body, which causes ammonia production, according to Mayo Clinic.

- What is Blood Urea Nitrogen (BUN)? Blood urea nitrogen (BUN) is a measure of the amount of urea in the blood . It provides useful information about your health. The liver produces urea as a waste product of the digestion of proteins (R, R). Urea is a safe vehicle to get rid of excess nitrogen from the body.

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.

BUN and Creatinine Levels What Are BUN and Creatinine? BUN stands for blood urea nitrogen. The BUN is a measurement that represents the level of urea in the blood. Urea is considered one of the body’s waste products. It is produced when the liver participates in protein metabolism, and it is usually eliminated from the body by the kidneys.

Medical Dictionary Blood urea nitrogen to creatinine ratio (BUN:creatinine). A BUN test may be done with a blood creatinine test. The level of creatinine in your blood also tells how well your kidneys are working-a high creatinine level may mean your kidneys are not working properly. blood urea nitrogen (BUN) test is done to: 1  See if your kidneys are working normally. 2  See if your kidney disease is getting worse. 3  See if treatment of your kidney disease is working.

- However, your feedback is important to us. A blood urea nitrogen (BUN) test checks kidney function by measuring how much urea nitrogen is in your blood. Urea nitrogen is a waste product from the breakdown of protein in the body. Normally, this waste is filtered by the kidneys and leaves the body through urine. Too much or too little urea nitrogen in the blood could signify kidney problems. The BUN test is frequently done along with other tests to diagnose or monitor kidney diseases.

Blood urea nitrogen BUN is an indication of renal (kidney) health. The normal range is 1.8-7.1 mmol/L or 6–20 mg/dL. Blood urea nitrogen levels can also help identify damage to body systems and diseases of the digestive, circulatory, and respiratory systems. The main causes of an increase in BUN are: high protein diet, decrease in glomerular filtration rate (GFR) (suggestive of renal failure) and in blood volume (hypovolemia), congestive heart failure, gastrointestinal hemorrhage, fever, and increased catabolism.
