Interpretation of aldosterone-to-renin ratio*44 | ||
Method for measuring renin | Weak positive result for ARR | Strong positive result for ARR |
Plasma renin activity (ng/mL/h) | 550–750 | > 750 |
Renin concentration (mU/L) | 60–90 | > 90 |
Renin concentration (ng/L) | 100–144 | > 144 |
Note: ARR = aldosterone-to-renin ratio.
↵* Dependent upon the method for renin measurement used by the local laboratory; however, standard reporting of aldosterone in pmol/L is assumed.
