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)) 

To calculate the renin aldosterone ratio, divide the mass concentration of aldosterone by the plasma renin activity.

How to Calculate Renin/Aldosterone Ratio?

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

  1. First, determine the mass concentration of aldosterone (ng/dL). 
  2. Next, determine the plasma renin activity (ng/(mL-h)). 
  3. Next, gather the formula from above = RA = R/A.
  4. Finally, calculate the Renin/Aldosterone Ratio.
  5. 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 = ?
