1) Aldosterone and Renin are ordered together, or
2) Aldosterone/Renin Ratio or PRA Ratio is written on the requisition
Position - Is the patient upright or lying down? For PSC and outpatients, enter "Upright".
Minutes in Position - How many minutes has the patient been in this position? For PSC and outpatients, calculate how many minutes the patient has been awake. If patient is unavailable to confirm and if not indicated on requisition, enter "0".

Aldosterone 1 x 3.5 mL gold top SST tube
|Specimen Handling||Aldosterone: Use label indicating GOLD SST.|
Renin: Three labels will print; use the 2 labels indicating SEE GTS for the aliquot tubes and the third label for the primary tube.
|Testing Frequency||Aldosterone - twice a week; Tuesdays and Thursdays.|
Renin - twice a week: Tuesdays and Thursdays.
|Alternate Name(s)||PRA (Plasma Renin Activity), PRA Ratio, Direct Renin Ratio|
|Reference Interval||An aldosterone (pmol/L) / renin concentration (mIU/L) ratio > 60 may be indicative of primary aldosteronism if drawn in the absence of confounding drugs. Clinical correlation or further investigation may be required for confirmation of this interpretation. |
