The typical ratio of BUN to creatinine in your blood is 10:1 to 20:1, according to the American Association for Clinical Chemistry.hen your liver filters proteins, it gives off urea nitrogen as a waste product. The kidneys are responsible for filtering the urea nitrogen out of your blood supply and into your urine. If a BUN test reveals higher-than-normal levels, your kidneys may not be working properly or as effectively as they should.
