Aldosterone:Renin Ratio >=31 pmol/mIU makes primary hyperaldosteronism (Conn's syndrome) more likely

Collection Conditions / Other Information:LAB INSTRUCTIONS: Use EALRE if renin also requested. Separate and freeze plasma.

Referred to Another Laboratory?No

Further information:Affected by most anti-hypertensives with the exception of alpha blockers, verapramil and hydralazine.
