The BUN to Creatinine Ratio Calculator is used to calculate the BUN to Creatinine Ratio (BUN:Cr).
In medicine, the BUN to creatinine ratio is the ratio of two serum laboratory values, the blood urea nitrogen (BUN) (mg/dL) and serum creatinine (Cr) (mg/dL). The ratio may be used to determine the cause of acute kidney injury.
The BUN to creatinine ratio calculation formula is as follows:
BUN to Creatinine Ratio = Blood urea nitrogen / Serum creatinine
