Certain factors, such as dehydration, pregnancy, high or low protein intake, steroids, and aging can impact your levels without indicating a health risk. Creatinine is a normal byproduct of muscle metabolism that is excreted by the kidneys, with normal serum values of about 0.6 mg/dL - 1.2 mg/dL. If there is a problem with your kidneys, creatinine can build up in your blood and less may be released in urine. Normally, your kidneys filter creatinine from your blood and remove it from your body in your urine. Its made when you use your muscles and some of the muscle tissue breaks down. However, abnormal BUN levels don’t necessarily mean you have a kidney condition. Creatinine is a normal waste product in your body. A medication wouldn’t be recommended to lower BUN levels. A low-protein diet can also help lower BUN levels. BUN/Creatinine Ratio between 10 and 20 is considered a normal value or may be suggestive of a post-renal cause of ARF. An eGFR higher than 60 means you have at least 60 kidney function. It drops to 85 mL/min/1.73m2 for people in their 60s. The average eGFR for someone in their 20s is about 116 mL/min/1.73m2. The rate naturally declines as you age and lose muscle mass. Proper hydration is the most effective way to lower BUN levels. Values for eGFR vary depending on age, sex and other factors. Keep in mind that some medications, such as certain antibiotics, can raise your BUN levels.ĭepending on your test results, your doctor may also run other tests to confirm a diagnosis or recommend treatments. In the United States only the nitrogen component of urea is measured (the blood urea nitrogen, i.e., BUN), which is roughly one-half of blood urea. Normal BUN levels for adults over 60 are slightly higher than normal levels for adults under 60. children 1 to 17 years old: 7 to 20 mg/dL.Abnormal BUN levels may indicate problems with liver or kidney functioning. In general, normal BUN levels fall in the following ranges: A BUN test measures the level of urea nitrogen in the blood using a standard blood sample. It’s also important to note that each laboratory has different ranges for what’s normal. Normally, the BUN:sCr ratio is about 15 : 1, with the BUN and sCr increasing by 10 to 15 and 1.0 to 1.5 mg/dL/day, respectively, in the absence of glomerular. The normal BUN level is between about 7 and 20 milligrams per deciliter (mg/dL). Normal BUN values tend to vary depending on gender and age. In normal circumstances, Both BUN and Cr are filtered. Renal damage causes reduced reabsorption of BUN, therefore lowering the BUN:Cr ratio.

Results of a BUN test are measured in milligrams per deciliter (mg/dL). Some sources say the normal range is 10-15:1.
