Why are BUN, Serum Creatinine, and BUN/Creatinine Ratio Assessed?Д«UN and serum creatinine are commonly assessed together to evaluate kidney function, to diagnose kidney disease, and to monitor patients with acute or kidney disease.Д«UN/creatinine ratio is useful in determining the more specific causes of abnormalities in the levels of BUN and serum creatinine.
