Renin Aldosterone Ratio Calculator

This calculator helps in determining the Renin Aldosterone Ratio (RAR) which is used to assess adrenal function and diagnose conditions like primary aldosteronism, hypertension, and renal artery stenosis.

Renin Aldosterone Ratio (RAR)

--

Calculation Formula

RAR = PRA / SAC

Where:
PRA = Plasma Renin Activity (ng/dL·h)
SAC = Serum Aldosterone Concentration (ng/dL)

How to Use the Calculator

  1. Enter the Plasma Renin Activity (PRA) in ng/dL·h. This measures the activity of renin in the blood.
  2. Enter the Serum Aldosterone Concentration (SAC) in ng/dL. This measures the concentration of aldosterone in the blood.
  3. Click the "Calculate" button to compute the Renin Aldosterone Ratio (RAR).
  4. The result will be displayed in the RAR field.

Interpreting the Results

The Renin Aldosterone Ratio (RAR) is used to assess adrenal function and diagnose conditions such as:

  • Primary Aldosteronism
  • Hypertension
  • Renal Artery Stenosis

A high RAR may indicate primary aldosteronism, while a low RAR may suggest secondary aldosteronism or other conditions affecting renin or aldosterone levels.

Normal Range

The normal range for the Renin Aldosterone Ratio (RAR) is typically between 0.2 and 2.0 ng/dL·h/ng/dL. However, this can vary based on individual factors and laboratory reference ranges.

Important Notes

It's important to consult with a healthcare professional for proper interpretation of the results. This calculator is for educational purposes only and should not be used as a diagnostic tool.
