Enter the total BUN (mg/dL) and the plasma Creatinine (mg/dL) into the Bun Creatinine Ratio Calculator. The calculator will evaluate and display the Bun Creatine Ratio.

## Bun Creatinine Ratio Formula

The following formula is used to calculate the Bun Creatinine Ratio.

BCR = TB / PC

• Where BCR is the Bun Creatinine Ratio ( )
• TB is the total BUN (mg/dL)
• PC is the plasma Creatinine (mg/dL)

## How to Calculate Bun Creatinine Ratio?

The following example problems outline how to calculate Bun Creatinine Ratio.

Example Problem #1:

1. First, determine the total BUN (mg/dL).
• The total BUN (mg/dL) is given as: 125.
2. Next, determine the plasma Creatinine (mg/dL).
• The plasma Creatinine (mg/dL) is provided as: 5.
3. Finally, calculate the Bun Creatinine Ratio using the equation above:

BCR = TB / PC

The values given above are inserted into the equation below and the solution is calculated:

BCR = 125 / 5 = 5 ( )

Example Problem #2:

For this problem, the variables required are provided below:

total BUN (mg/dL) = 160

plasma creatine (mg/dL) = 7

Test your knowledge using the equation and check your answer with the calculator above.

BCR = TB / PC = ?
