At a Glance
Blood urea nitrogen 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 6 to 20 mg/dL of urea nitrogen.BUN and creatinine levels that are within the ranges established by the laboratory performing the test suggest that your kidneys are functioning as they should. Increased BUN and creatinine levels may mean that your kidneys are not working as they should.BUN is to evaluate the health of your kidneys, to help diagnose kidney disease, to monitor the effectiveness of dialysis and other treatments related to kidney disease or damage. Urea is a waste product formed in the liver when protein is metabolized into its component parts (amino acids). This process produces ammonia, which is then converted into the less toxic waste product urea. This test measures the blood urea nitrogen (BUN) level in the blood. Sometimes, a bun to cr ratio is calculated to help determine the cause of elevated levels.
When BUN Test Ordered?
Your doctor may order a blood urea nitrogen test as part of a routine health screening. It helps her see how well your kidneys are working. BUN is often ordered with creatinine or renal panel when it is suspected that you have a kidney problem with signs and symptoms such as Blood and/or protein in your urine ,Swelling or puffiness (edema), particularly around the eyes or in the face, wrists, abdomen, thighs, or ankles, Urine that is foamy, bloody, or coffee-colored, A marked decrease in the amount of urine, Problems urinating, frequency of urination, especially at night, Mid-back pain (flank), below the ribs, near where the kidneys are located, High blood pressure (hypertension).
BUN/Creatinine Ratio
The bun cr ratio blood test is used to diagnose acute or chronic renal (kidney) disease or damage. It may also be used to determine gastrointestinal bleeding or trauma. BUN (blood urea nitrogen) and creatinine are both filtered in the kidneys and excreted in urine. The two together are used to measure overall kidney function. Once a person performs both a BUN and Creatinine test, doctors can use the combined results to find the BUN-to-creatinine ratio. The BUN and creatinine tests alone are excellent methods of testing liver and kidney health, but together, doctors get a much better understanding of your kidney health and can provide a more accurate diagnosis to kidney-related issues .Are you searching "where to get blood work done" for bun cr ratio test?.
