Creatinine is a natural product of muscle breakdown that occurs at a low level in the body. Both BUN and creatinine are filtered by the kidney and excreted in urine. For this reason, BUN and creatinine are used together to measure kidney function. If kidney function begins to decline, BUN and creatinine rise. A normal creatinine depends on muscle mass and age. In general, a normal creatine is 0.5 to 1.2 milligrams per deciliter (mg/dL). A normal BUN is 7 to 20 mg/dL. Remember that different laboratories use different testing equipment, and may have slightly different ranges for normal.
Bun and creatinine. Question: Recent labwork revealed an elevated BUN of 34 w/ a ref range of 5-26. Creatinine was 0.69 w/ ref range of 0.5-1.50. BUN/creatinin ratio was elevated at 49 w/ ref range of 8 to 27. This was a fasting sample (approx 12 hours w/o food or drink)....
