BUN to Creatinine Ratio Calculator

Formula

To calculate the BUN to Creatinine Ratio (BCR):

\[ BCR = \frac{BUN}{Cr} \]

Where:

\(BCR\) is the BUN to Creatinine Ratio
\(BUN\) is the blood urea nitrogen level (mg/dL)
\(Cr\) is the creatinine level (mg/dL)

What is the BUN to Creatinine Ratio?

The BUN to Creatinine Ratio is a measure used to help diagnose and monitor kidney function. It is calculated by dividing the blood urea nitrogen level by the creatinine level. Abnormal ratios can indicate various conditions, including dehydration, kidney disease, or other underlying health issues.

Example Calculation 1

Let's assume the following values:

BUN (\(BUN\)) = 20 mg/dL
Creatinine (\(Cr\)) = 1.0 mg/dL

Using the formula:

\[ BCR = \frac{20}{1.0} = 20 \]

The BUN to Creatinine Ratio is 20.

Example Calculation 2

Let's assume the following values:

BUN (\(BUN\)) = 15 mg/dL
Creatinine (\(Cr\)) = 0.8 mg/dL

Using the formula:

\[ BCR = \frac{15}{0.8} = 18.75 \]

The BUN to Creatinine Ratio is 18.75.
