Enter the mass concentration of aldosterone (ng/dL) and the plasma renin activity (ng/(mL-h)) into the Renin/Aldosterone Ratio Calculator. The calculator will evaluate the Renin/Aldosterone Ratio.

## Renin/Aldosterone Ratio Formula

The following two example problems outline the steps and information needed to calculate the Renin/Aldosterone Ratio.

**RA = R/A**

Variables:

- RA is the Renin/Aldosterone Ratio (ng/(mL-h) / (ng/dL))
- A is the mass concentration of aldosterone (ng/dL)
- R is the plasma renin activity (ng/(mL-h))

## How to Calculate Renin/Aldosterone Ratio?

The following steps outline how to calculate the Renin/Aldosterone Ratio.

- First, determine the mass concentration of aldosterone (ng/dL).
- Next, determine the plasma renin activity (ng/(mL-h)).
- Next, gather the formula from above = RA = R/A.
- Finally, calculate the Renin/Aldosterone 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.

mass concentration of aldosterone (ng/dL) = 30

plasma renin activity (ng/(mL-h)) = 14

RA = R/A** **= ?
