Blood Urea Nitrogen/Creatinine Ratio (BUN/Cr) Risk Class Calculator
Blood Urea Nitrogen/Creatinine (BUN/Cr) Ratio: Explanation and Clinical Context The BUN/Cr ratio is a commonly used biochemical marker to assess the relative elevation of blood urea nitrogen compared to serum creatinine. It is widely applied in the context of acute kidney injury (AKI), volume depletion, and other renal and systemic conditions. A BUN/Cr ratio <10 is generally considered low risk, indicating a low like
