A low urea-to-creatinine ratio may be caused by a diet low in protein, a severe muscle injury called rhabdomyolysis, pregnancy, cirrhosis, or syndrome of inappropriate antidiuretic hormone secretion (SIADH).Women and children may have lower urea levels than men because of how their bodies break down protein.Drinking excessive amounts of liquid may cause overhydration and cause a low urea value.A low urea value may be caused by a diet very low in protein, malnutrition, or severe liver damage.A very high urea-to-creatinine ratio may be caused by bleeding in the digestive tract or respiratory tract. High urea-to-creatinine ratios occur with sudden (acute) kidney problems, which may be caused by shock or severe dehydration.A high urea value may be caused by a high-protein diet, Addison's disease, tissue damage (such as from severe burns), or from bleeding in the gastrointestinal tract.Be sure to tell your doctor about all the non-prescription and prescription medicines you take. Many medicines may cause a high urea level.High urea levels can also be caused by low blood flow to the kidneys caused by dehydration or heart failure. Kidney damage can be caused by diabetes or high blood pressure that directly affects the kidneys. A high urea value can mean kidney injury or disease is present.A value that isn't in the normal range may still be normal for you. Your doctor will also look at your results based on your age, health, and other factors. Your lab report should show the range that your lab uses for each test. A urea-to-creatinine ratio can help your doctor check for problems, such as dehydration, that may cause abnormal urea and creatinine levels.Įach lab has a different range for what's normal. Urea and creatinine tests can be used together to find the urea-to-creatinine ratio (urea:creatinine). 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. Urea to creatinine ratio (urea:creatinine)Ī urea test may be done with a blood creatinine test. A low urea level can occur normally in the second or third trimester of pregnancy. Liver disease or damage can lower your urea level. Heart failure, dehydration, or a diet high in protein can also make your urea level higher. If your kidneys are not able to remove urea from the blood normally, your urea level rises. Urea is made in the liver and passed out of your body in the urine.Ī urea test is done to see how well your kidneys are working. Urea is made when protein is broken down in your body. Some disorders related to a low BUN level in the blood are pregnancy and acromegaly.A blood urea nitrogen (BUN) or urea test measures the amount of nitrogen in your blood that comes from the waste product urea. If kidneys do not work properly urea remains in the bloodstream and its concentration in the blood will be abnormally higher.Ī BUN level below the normal range may be a sign of a low-protein diet or a liver disorder (the liver is not doing a proper protein metabolism). Kidney disorders ( kidney failure, nephropathies, etc.).High protein catabolism (due to an excessive consumption of proteins, etc.).A decrease in the plasma volume due to dehydration or upper GI (gastrointestinal) bleeding.Urea level in the blood is directly related to nutrition, protein metabolism/catabolism and renal functionality.Ī high level of BUN in the blood may be due to: Urea is a marker for kidneys and liver activity. Maximum values increase with the age and are higher in elderly people. Age is an important factor to normal ranges.If your test is expressed in urea you must convert the values from urea to BUN or the information given will not be specific for your case. A BUN test can help uncover kidney problems at an early stage. People with early kidney disease may not have any symptoms. Higher than normal BUN levels may be a sign that your kidneys arent working well. Urea nitrogen is a waste product that your kidneys remove from your blood. Warning: In this page we talk about BUN levels. The BUN test measures the amount of urea nitrogen in your blood. It important to know if the values measured are the BUN levels used in the US and other countries or instead the values measured are the total urea used in Europe and around the world.There are some circumstances to take into account about BUN normal ranges in the blood: Your doctor will study the results along with your medical record, screenings, physical condition, symptoms and any other relevant information about your situation. There may be also slight differences in the normal levels according to age, gender, race or ethnic origin, geographic region, diet, type of sample and other relevant status. These ranges depend on the makeup of the local population, the technologies used and the accuracy of the measurement. Each laboratory must establish its own normal ranges for BUN in the blood.
