Renin

Renin

Reference Range

From 1/3/18 renin samples are analysed using the IDS iSYS direct renin mass immunoassay which will use the following reference ranges:

Ambulatory:  Female: 6.1 – 62.7 mIU/L,  Male: 9.0 – 103 mIU/L

Supine: 4.2 – 59.7 mIU/L

Screen positive for Conns: Aldosterone/renin ratio >91pmol/mU + aldosterone >750 pmol/L

(Endocrine guidelines on the investigation of Conns https://doi.org/10.1210/jc.2015-4061)

The Aldosterone/Renin ratio cut-off that we are providing is a guide only and not a diagnostic test and the ratio should be interpreted, cautiously, in conjunction with relevant clinical information and medications that may affect the ratio.
