Urea nitrogen is a waste product that your kidneys remove from your blood. Generally, a normal BUN range is between 7 to 20. The BUN test measures the amount of urea nitrogen in your blood. In most cases of chronic renal disease, the ratio remains relatively normal. The normal blood urea nitrogen (BUN) levels can vary depending on the laboratory and individual factors. It allows the doctors to learn about your kidney and liver performance. When there is decreased formation of urea, as seen in liver disease, there is a decrease in the BUN/Creatinine ratio. A Blood Urea Nitrogen (BUN) test measures the amount of nitrogen in your blood. 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. And an example of normal ranges for the values. Standard or normal ranges for a BMP are: Na: 134 to 144 mmol/L. BUN levels in toddlers are around 66 of the levels found in an. When you look at your results, it will likely include the normal range for that specific lab. Generally, blood urea nitrogen levels increase with increasing age. BUN levels also change with gender and age and during pregnancy. High creatinine levels that reach 2.0 or more in babies and 5.0 or more in adults may indicate severe kidney impairment. A result greater than 50 mg/dL indicates an underlying medical problem. A person with only one kidney may have a normal level of about 1.8 or 1.9. To calculate the new eGFR from a previous Creatinine or Cystatin C result, go to. The range of normal levels of blood urea nitrogen is between 7 and 22 mg/dL. The eGFR is based on the CKD-EPI 2021 equation.
