4/11/2024 0 Comments What is bun normal rangeThe doctors use both BUN and Creatinine tests to check out the BUN to Creatinine ratio. The rate of creatinine formation depends on the individual’s muscle mass.Īs creatinine production reflects muscle mass, it can change little from day to day due to mass change.Īn excessive amount of creatinine is a sign of impaired kidney function or kidney disease. It comes from creatinine, a protein that helps generate energy for muscle contraction and is transported through the bloodstream to the kidneys, where it is filtered and excreted through the urine. What Is a Creatinine Test?Ĭreatinine is a type of molecule or waste product that is generated from muscle wear and tear. High levels of urea may be a sign of some kidney problem that needs medical attention. Having some urea in the blood is normal as the liver is constantly producing it. Optimal functioning kidneys then filter and remove other waste products like urea through urination. The nitrogen comes from the waste product urea converted from nitrogen and produced in the liver when protein is metabolized after eating. It allows the doctors to learn about your kidney and liver performance. In most cases of chronic renal or kidney damage, this ratio stays relatively normal.Ī Blood Urea Nitrogen (BUN) test measures the amount of nitrogen in your blood.When there is a decline in the formation of urea, the ratio of BUN/Creatinine also goes down.Increased urea formation can also increase the ratio, such as gastrointestinal bleeding and trauma, etc.Reduced kidney perfusion such as congestive heart failure or recent onset of urinary tract obstruction can lead to an increase in the BUN/Creatinine ratio.The BUN/Creatinine ratio helps with differential diagnosis of acute or chronic kidney disease.Some essential factors to know about BUN/Creatinine blood test When the BUN levels are studied with the creatinine levels, it gives a better picture of what is happening with the kidneys. It is the reason a creatinine test is also needed. The BUN level alone does not reveal much about kidney health. It allows the healthcare providers to assess how well the kidneys are functioning. Together, they help in measuring the overall kidney function. They can also determine gastrointestinal bleeding or trauma in some cases.īlood urea nitrogen and creatinine are both filtered in the kidney and excreted in the urine. And while they can be tested separately, the BUN/creatinine ratio can help pinpoint significant health issues. These tests reveal a lot about your metabolism, kidney, liver, and overall health. What Is a Bun/Creatinine Ratio Test?īUN (blood urea nitrogen) and creatinine are two blood tests used for diagnosing acute or chronic kidney damage or disease. The internal medicine doctors at the Century Medical and Dental Center focus on diagnosing your renal problems and use the test results to recommend the best treatment. The BUN/Creatinine ratio blood test measures the overall kidney functions and detects any sign of metabolic disease or liver damage. If you have a family history of kidney disease or suffer from diabetes and high blood pressure, get your BUN and creatinine ratio tested as urea and creatinine are filtered in the kidney and excreted in the urine. Early kidney disease is a silent problem, and you may not know about it until you begin to feel the symptoms and it is too late to reverse it.
