Direct renin measurement (new methodology from March 2016) can be used in conjuction with aldosterone for an aldosterone renin ratio to aid in the investigation of primary hyperaldosteronism.

<30Primary aldosteronism unlikely
≥30<250Primary aldosteronism unlikely (aldo not in range associated with PA)
≥30250 - 399Primary aldosteronism not excluded (aldo typically >400 in PA)
≥30≥400Consistent with primary aldosteronism (suggest confirmatory testing

Please see link for guidance on the management of Primary Aldosteronism.
