The CCR is typically measured in ml/min. Normal Values of BUN and Creatinine. Clinicians frequently calculate a convenient relationship, the urea nitrogen:creatinine ratio-serum bun in mg/dL/serum creatinine in mg/dL. A normal ratio of BUN:creatinine is anywhere in the range of 10:1 to 20:1. Find out the BUN to creatinine ratio if blood urea nitrogen is 4 mg/dL and serum creatinine is 2 mg/dL. Moreover, the values from the tests are evaluated based on other factors and on an individual’s health.

BUN to creatinine ratio specifies the ratio of two serum laboratory values, the blood urea nitrogen and serum creatinine,this ratio is used to evaluate the cause of acute kidney damage. Serum blood urea nitrogen (BUN) determinations are considerably less sensitive than BUN clearance (and creatinine clearance) tests, and levels may not be abnormal until the BUN clearance has diminished to less than 50%. In the US the urea is expressed as BUN (Blood Urea Nitrogen) in mg/dL. 1986 May;4(2):223-33.
