Blood urea nitrogen Blood urea nitrogen (BUN) is a medical test that measures the amount of urea nitrogen found in blood. The liver produces urea in the urea cycle as a waste product of the digestion of protein. Normal human adult blood should contain between 6 and 20 mg of urea nitrogen per 100 ml (6–20 mg/dL) of blood.

Medical Dictionary A 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.  Check for severe dehydration. Dehydration generally causes BUN levels to rise more than creatinine levels.

BUN Blood urea nitrogen. A measure of serum urea, a by-product of the breakdown of blood, muscle and protein. Urea is cleared by the kidney; diseases that compromise renal function lead to increased BUN. Increased in. Renal disease, dehydration, CHF, GI bleeding, starvation, shock, urinary tract obstruction (e.g., by tumour or prostate gland).

- BUN stands for blood urea nitrogen. Creatinine is a natural product of muscle breakdown that occurs at a low level in the body. Both BUN and creatinine are filtered by the kidney and excreted in urine. For this reason, BUN and creatinine are used together to measure kidney function. If kidney function begins to decline, BUN and creatinine rise. A normal creatinine depends on muscle mass and age. In general, a normal creatine is 0.5 to 1.2 milligrams per deciliter (mg/dL). A normal BUN is 7 to 20 mg/dL.

Understanding Your Lab Values Blood Urea Nitrogen (BUN): Urea nitrogen is a normal waste product in your blood that comes from the breakdown of protein from the foods you eat and from your body metabolism. It is normally removed from your blood by your kidneys, but when kidney function slows down, the BUN level rises.

What are BUN-Creatinine Levels? BUN (blood urea nitrogen) is a blood test to check kidney function. So is the serum creatinine test. When your doctor talks about BUN/creatinine levels or a BUN-to-creatinine ratio, he or she is referring to the two main blood tests that tell how well the kidneys are filtering waste products from your blood. The ratio of BUN to creatinine is normally in the range of 10:1 to 20:1.

What Does High BUN Mean For kidney failure patients, they may found there shows high level of BUN in their rest report. So what does it mean? Is high BUN a dangerous sign for kidney failure patients? What does high BUN mean? To know clearly about it. Now, let’s learn what BUN is firstly. BUN is the abbreviation of Blood Urea Nitrogen and refers to urea nitrogen in blood. For an healthy adult individual, his BUN level should be in the range 6 to 20mg/dL (3.2-7.1mmol/L). Urea nitrogen is a waste product of the digestion of protein and mainly discharged through our kidneys. Therefore, high BUN level is always closely related with kidney condition. Kidney failure is a common cause for high BUN, but it is not the only cause. In clinic, aside from kidney problem, many other factors like high protein intake, severe dehydration and hepatorenal syndrome also can cause elevation of BUN.

BUN 26: What does it mean? In general, the normal BUN level for healthy individuals is 7-20 mg/dL (2.5 to 7.1 mmol/L) in adults, and 5-18 mg/dL in children. But normal ranges may vary, depending on the reference range used by the lab, and your age. Infants have lower levels than other people do.

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 principle behind this ratio is the fact that both urea (BUN) and creatinine are freely filtered by the glomerulus, however urea reabsorbed by the tubules can be regulated (increased or decreased) whereas creatinine reabsorption remains the same (minimal reabsorption).

BUN 26: What does it mean? The BUN level of 26 is much higher than the normal range. The main causes of an increase in BUN are: high protein diet, decrease in Glomerular Filtration Rate (GFR) which implies kidney damage, low blood volume (hypovolemia), congestive heart failure, gastrointestinal hemorrhage, fever and increased catabolism.

What does a consistent low BUN result in a blood test mean? BUN is part of both the BMP and CMP, groups of tests that are widely used: 1  As part of a routine health checkup. 2  To check how the kidneys are functioning before starting to take certain drug therapies.  When an acutely ill person comes to the emergency room and/or is admitted to the hospital.

Blood Urea Nitrogen (BUN) Test A blood urea nitrogen (BUN) test is used to determine how well your kidneys are working. It does this by measuring the amount of urea nitrogen in the blood. Urea nitrogen is a waste product that’s created in the liver when the body breaks down proteins. Normally, the kidneys filter out this waste, and urinating removes it from the body. BUN levels tend to increase when the kidneys or liver are damaged.

A normal BUN-to-creatinine ratio is between 10 to 1 and 20 to 1. (For example, a BUN of 14 and a creatinine of 1.2 would be a ratio of 12.).

- 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.

What is the employer's Social Security tax rate for 2018? The employer's Social Security tax rate for 2016 is 6.2% of each employee's first $118,500 of wages, salaries, etc. If an employee's wages, salaries, etc. are greater than $118,500, the amount that is in excess of $118,500 is not subject to the Social Security tax. Hence, the maximum amount of the employer's Social Security tax for each employee in 2016 is $7,347 (6.2% X $118,500). (The percentage and the earnings limit are unchanged from 2015.) (Employees also pay a Social Security tax. In effect, the employer is matching each employee's Social Security tax.)

BUN (Blood Urea Nitrogen) Test The BUN test is conducted to check the functioning of the kidneys. The kidneys are a pair of organs that are tasked with the function of cleaning the blood. Blood is used as a transport medium for nutrients and hormones to various parts of the body. Blood is also used to remove wastes from these parts of the body.
