## Ca/Cr Ratio Formula

Ca:Cr = Ca/Cr

Variables:

- Ca:Cr is the Ca/Cr Ratio ()
- Ca is the total calcium (mg/dL)
- Cr is the total creatinine level (mg/dL)

To calculate Ca/Cr Ratio, divide the total calcium by the total creatinine.

## How to Calculate Ca/Cr Ratio?

The following steps outline how to calculate the Ca/Cr Ratio.

- First, determine the total calcium (mg/dL).
- Next, determine the total creatinine level (mg/dL).
- Next, gather the formula from above = Ca:Cr = Ca/Cr.
- Finally, calculate the Ca/Cr Ratio.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

total calcium (mg/dL) = 5

total creatinine level (mg/dL) = 6
