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

For interpretation of the aldosterone:renin ratio in the context of hypertension please see Figure 1 in Primary Aldosteronism: An Endocrine Society Clinical Practice Guideline | The Journal of Clinical Endocrinology & Metabolism | Oxford Academic.  (Please note our aldosterone method is LC-MS/MS in pmol/L and our renin method is Direct Renin Concentration (DRC)).

Therapeutic concentrations of risperidone range between 10 and 90 μg/L, and the total sum of risperidone and 9-hydroxyrisperidone range between 10 and 100 μg/L.
