BUN to Creatinine Ratio Calculator
Result
BUN to Creatinine Ratio Calculator Calculate the BUN-to-creatinine ratio from your blood urea nitrogen and serum creatinine values — a lab ratio used to help distinguish causes of kidney dysfunction. Enter both lab values in mg/dL to get the ratio and a g — free online calculator.
Formula
- BUN to Creatinine Ratio Calculator calculates its result from Bun, Serum Creatinine Both In Mg Dl. It uses the formula Ratio = BUN ÷ serum creatinine (both in mg/dL). Change any input to recalculate the result instantly. This is an informational calculation and is not medical advice.
- The main inputs are Bun, Serum Creatinine Both In Mg Dl. Enter them in the units and format shown in the calculator.
- Use the measurement units shown beside each field. The result is an estimate and should be interpreted in context.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: BUN to Creatinine Ratio
- Bun: 2
- Serum Creatinine Both In Mg Dl: 11
Using Bun = 2, Serum Creatinine Both In Mg Dl = 11, the calculated result is 0.1818181818.
