What is the meaning of urea test? A blood urea nitrogen (BUN) test measures the amount of urea in a sample of blood. Urea is a waste product that forms as part of the body’s natural process of breaking down proteins. It is also referred to as urea nitrogen and is filtered out of the blood by the kidneys.
What is urea test used for? Test Overview
A blood urea nitrogen (BUN) test measures the amount of nitrogen in your blood that comes from the waste product urea. Urea is made when protein is broken down in your body. Urea is made in the liver and passed out of your body in the urine. A BUN test is done to see how well your kidneys are working.
What is normal urea test? In general, around 6 to 24 mg/dL (2.1 to 8.5 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.
What happens if urea is low? Low urea levels are not common and are not usually a cause for concern. They can be seen in severe liver disease or malnutrition but are not used to diagnose or monitor these conditions. Low urea levels are also seen in normal pregnancy. Urea levels increase with age and also with the amount of protein in your diet.
What is the meaning of urea test? – Related Questions
What does high urea mean?
A high BUN value can mean kidney injury or disease is present. Kidney damage can be caused by diabetes or high blood pressure that directly affects the kidneys. High BUN levels can also be caused by low blood flow to the kidneys caused by dehydration or heart failure.
What level of urea indicates kidney failure?
A GFR below 60 is a sign that the kidneys are not working properly. Once the GFR decreases below 15, one is at high risk for needing treatment for kidney failure, such as dialysis or a kidney transplant. Urea nitrogen comes from the breakdown of protein in the foods you eat. A normal BUN level is between 7 and 20.
Can drinking water reduce blood urea?
Results: Serum urea and folic acid concentration decreased up to 40% after administration of the water load in 24 hours. Serum creatinine concentration decreased up to 20% after administration of the water load in 30 minutes.
What is the cause of low urea?
There are two physiological causes of reduced concentration: low-protein diet, and pregnancy. Low-protein diet is associated with reduced urea production and consequent tendency to reduced plasma/serum urea concentration.
What is low urea in blood test means?
If you have low BUN levels, it could indicate: ● Liver disease. ● Malnutrition (when your diet doesn’t have enough nutrients or your body can’t take them in well) ● Overhydration (having too much fluid) But a BUN test is not a way to diagnose these issues, so more tests may be needed.
How does high urea affect the body?
Uremia can lead to kidney failure when left untreated. Someone with uremia may have seizures, loss of consciousness, heart attacks, and other life-threatening symptoms. Some will need a kidney transplant. Kidney failure may also damage other organs, so untreated uremia can result in liver or heart failure.
What is normal range of urea and creatinine?
We defined the normal range as range within the single SD-line of the remainder. 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 female.
Which test is for kidney?
Your kidney numbers include 2 tests: ACR (Albumin to Creatinine Ratio) and GFR (glomerular filtration rate). GFR is a measure of kidney function and is performed through a blood test. Your GFR will determine what stage of kidney disease you have – there are 5 stages.
Can kidneys repair themselves?
It was thought that kidney cells didn’t reproduce much once the organ was fully formed, but new research shows that the kidneys are regenerating and repairing themselves throughout life.
Is drinking water at night bad for kidneys?
Given the quantity of blood that filters through your kidneys on an hourly basis, those few extra cups are as insignificant to your kidneys as barnacles are to a battleship. So the best time to drink water is not at night.
Does lemon water reduce urea?
A lemon should not increase uric acid levels and should not increase the serum creatinine. It will increase citrate elimination in the urine which can decrease the rate of kidney stone formation.
How can I check my kidneys at home?
One of the best ways to test for CKD and assess kidney damage is a simple urine test which detects the presence of albumin. The smartphone app from Healthy.io enables lay users to conduct a urinalysis test at home and securely share results with their clinicians.
What drinks are bad for kidneys?
According to the American Kidney Fund, a recent study suggests that drinking two or more carbonated sodas, diet or regular, each day may increase your risk for chronic kidney disease. Carbonated and energy drinks have both been linked to the formation of kidney stones.
What color is urine when your kidneys are failing?
Light-brown Urine.
Light-brown or tea-colored urine can be a sign of kidney disease or failure or muscle breakdown.
Are eggs bad for kidneys?
Although egg yolks are very nutritious, they contain high amounts of phosphorus, making egg whites a better choice for people following a renal diet. Egg whites provide a high quality, kidney-friendly source of protein.
Can dehydration cause high urea?
Dehydration generally causes urea levels to rise more than creatinine levels. This causes a high urea-to-creatinine ratio. Kidney disease or blockage of the flow of urine from your kidney causes both urea and creatinine levels to go up.
Is milk good for kidney patients?
Yet people with chronic kidney disease (CKD) have to limit dairy products in their kidney diet. High levels of phosphorus, potassium and calcium in something like low-fat milk are not good for someone on a kidney diet.
Where does urea produce?
Urea is produced in the liver and is a metabolite (breakdown product) of amino acids. Ammonium ions are formed in the breakdown of amino acids.
Is Apple good for kidney?
An apple is a healthful snack that contains an important fiber called pectin. Pectin may help reduce some risk factors for kidney damage, such as high blood sugar and cholesterol levels.
Where is kidney pain felt in the body?
Pain from the kidneys is felt in the sides, or in the middle to upper back (most often under the ribs, to the right or left of the spine). The pain may also progress to other areas, such as the abdomen or groin. Kidney pain is a result of swelling or blockage in the kidneys or urinary tract.

The typical range for serum creatinine is: For adult men, 0.74 to 1.35 mg/dL (65.4 to 119.3 micromoles/L) For adult women, 0.59 to 1.04 mg/dL (52.2 to 91.9 micromoles/L)
