Renin/Aldosterone Ratio Calculator

Formula

The formula to calculate the Renin/Aldosterone Ratio is:

\[ \text{RA} = \frac{A}{R} \]

Where:

\( \text{RA} \) 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))

What is the Renin/Aldosterone Ratio?

The Renin/Aldosterone Ratio (RA) is a diagnostic measure used in the assessment of conditions such as primary aldosteronism. It is calculated by dividing the concentration of aldosterone by the plasma renin activity. This ratio helps in understanding the balance and relationship between aldosterone, a hormone that regulates sodium and potassium levels, and renin, an enzyme that plays a key role in the body's blood pressure regulation.

Example Calculation

Let's assume the following values:

Aldosterone (A) = 15 ng/dL
Renin (R) = 1.5 ng/(mL-h)

Using the formula to calculate the Renin/Aldosterone Ratio:

\[ \text{RA} = \frac{15}{1.5} = 10 \text{ ng/(mL-h) / (ng/dL)} \]

The Renin/Aldosterone Ratio (RA) is 10 ng/(mL-h) / (ng/dL).
