Ca:Cr Ratio Calculator

Formula

The formula to calculate Ca:Cr Ratio is:

\[ \text{Ca:Cr} = \frac{Ca}{Cr} \]

Where:

\( \text{Ca:Cr} \) is the Calcium to Creatinine Ratio
\( Ca \) is the Total Calcium (mg/dL)
\( Cr \) is the Total Creatinine (mg/dL)

What is the Ca:Cr Ratio?

The Ca:Cr Ratio (Calcium to Creatinine Ratio) is a clinical measurement used to assess the amount of calcium excreted relative to creatinine. This ratio is commonly used in diagnosing and monitoring various medical conditions, such as hypercalciuria, which is an excessive excretion of calcium in the urine. The Ca:Cr Ratio is important because it helps to evaluate the balance between calcium and creatinine, providing insight into kidney function and calcium metabolism.

Example Calculation

Let's consider an example:

Total Calcium (Ca): 8.5 mg/dL
Total Creatinine (Cr): 1.2 mg/dL

Using the formula to calculate Ca:Cr Ratio:

\[ \text{Ca:Cr} = \frac{8.5}{1.2} \approx 7.08 \]

This means that the Ca:Cr Ratio is approximately 7.08.
