On the other hand, a low BUN level may indicate liver diseases, malnutrition, overhydration, or certain other medical conditions. It is essential to remember that elevated BUN levels alone are not diagnostic of a specific condition, and further evaluation is necessary to determine the underlying cause. High BUN levels may also occur due to dehydration, gastrointestinal bleeding, heart conditions, urinary tract obstruction, certain medications (such as NSAIDs, ACE inhibitors, or ARBs), or other factors. In addition, children typically have higher levels of BUN compared to adults.Ī high BUN level may indicate that your kidneys are not functioning correctly and the urea is not filtering out in the urine. However, it's important to note that the specific reference range provided by the laboratory conducting the test should be considered. On average, for adults, the normal range of BUN is between 6 to 20 milligrams per deciliter (mg/dL). The normal range of BUN differs across age groups and can vary based on different factors and the laboratory's reference range. While measuring BUN levels, healthcare professionals generally evaluate blood urea nitrogen/creatinine ratio (BUN/Cr) to assess kidney function. BUN measures the concentration of nitrogen in the blood that comes from urea. The kidneys filter out urea from the bloodstream and eliminate it through urine. These byproducts are released into the bloodstream and carried to the liver, where they are converted into urea. Urea is a waste product generated by our bodies' breaking down proteins into amino acids, which are further broken down into ammonia and carbon dioxide. To understand BUN, we need to understand its basic science. This guide is intended to provide general information and insights into BUN and should not serve as a substitute for medical advice. Therefore, it's always recommended to follow the advice of a healthcare professional. Before delving into the various aspects of BUN, it's important to note that interpreting BUN results can be complex. In this comprehensive guide to BUN, we will explore the science behind BUN, how to interpret BUN results, its significance in kidney function, and the clinical applications of BUN. ![]() BUN is an essential laboratory test that provides crucial information about our body's metabolic activity and can help diagnose various medical conditions. BUN is a laboratory test that detects the amount of urea nitrogen in your blood, which is a byproduct of protein metabolism targeted by the kidneys to filter out of the body via urine. Your BUN Creatinine ratio test results will typically be available within a few hours after this procedure.Blood Urea Nitrogen, or BUN, is a common term you might come across during your routine medical checkup. ![]() A pathologist, a specialist in studying diseases, will collect a small blood sample from your veins using a needle. When your doctor recommends a BUN Creatinine ratio test, you'll likely undergo a simple blood draw specifically targeting the measurement of BUN Creatinine ratio. ![]() This page was viewed the most from these cities in the last 30 days:Īmbasamudram Santa Caterina Albanese Lempaut Tambra Island Rajgir Villard, Haute-Savoie Ernemont-Boutavent Margny-aux-Cerises Liang (state) Orland Park, Illinois Panchvalley Fraissinet-de-Fourques Rangmahal Roman Catholic Diocese of Valence Big Razorback Island Aix-Noulette Kondumal Chikhale, Panvel Bethon Qazigund Nuclear Energy Agency Birpur Quingentole Kizer Island Roy-Boissy Hérimoncourt Sambaragi Petitmont Pujols-sur-Ciron Marcheprime British rule in Burma Sambalpur State Zio Prefecture Kuchaikote (community development block) Le Havre Poggio-di-Venaco Surajkaradi Roman Empire Tughlaq dynasty Fakirbhudihal La Couvertoirade Becks Mill, Indiana Le Gua, Isère Soirans Lironcourt Gamaches-en-Vexin Chas block Anse Rodrigue, les Saintes Chavand Blue Grass, Iowa Important : How our patients treated their
