Symptoms of liver and kidney diseaseĪccording to the Centers for Disease Control and Prevention (CDC), an estimated 15 percent of adults in the United States have long-term kidney disease, known as chronic kidney disease. A doctor may carry out a BUN test alongside other kidney tests, such as the serum creatinine test. The BUN test requires only a blood sample. Kidney and liver conditions are common in adults, but they are easy to overlook or mistake for other disorders. A doctor will most often request a BUN test along with other related lab tests if they suspect kidney or liver diseases. This is not technically correct, but the two go hand-in-hand and measuring the level of this in the bloodstream helps to give a reliable indication of kidney and liver health.Ī component of many other blood tests, a doctor can order a BUN test for any person, even if they have no apparent symptoms or underlying conditions. Urea contains nitrogen and is also the compound responsible for helping clear excess nitrogen from the body.įor this reason, people often refer to both “urea” and “urea nitrogen” as the same compound. The liver releases urea into the blood, and it travels to the kidneys for removal in the urine. The liver produces urea as part of the body’s process of breaking down protein.

The liver and kidneys influence BUN levels profoundly, as they are responsible for breaking down protein and managing the waste. Healthcare professionals use BUN tests for a variety of reasons, including monitoring kidney and liver function.

In most cases of chronic renal disease, the ratio remains relatively normal. When there is decreased formation of urea, as seen in liver disease, there is a decrease in the BUN/Creatinine ratio. Increased urea formation also results in an increase in the ratio, e.g. congestive heart failure or recent onset of urinary tract obstruction, will result in an increase in BUN/Creatinine ratio. Please Note: If results for BUN and Creatinine are both within the normal reference range, the BUN/Creatinine ratio will not be reported (not applicable).Ĭlinical Significance: The BUN/Creatinine ratio is useful in the differential diagnosis of acute or chronic renal disease. To calculate the new eGFR from a previous Creatinine or Cystatin C result, go to. The eGFR is based on the CKD-EPI 2021 equation. Methodology: Photometric Assay, Calculation Transport: Store serum at 2☌ to 8☌ after collection and ship the same day per packaging instructions included with the provided shipping box.Ĭauses for Rejection: Specimens other than serum improper labeling samples not stored properly samples older than stability limits
