| 13th August 2024 | Collection & Request Instructions |
Collection Requirements for both or either tests
Collect into 4 mL EDTA tubes at Room Temperature. Do not collect on ice
If both Renin and Aldosterone are requested together, they can be collected into the same EDTA tube
Renin is stable in whole blood for up to 6 hours at room temperature.
In the laboratory, spin and separate the plasma. Plasma is stable at Room Temperature for up to 2 days.
Renin must be frozen at -70 C. if unable to test within 2 days.
Transport plasma at room temperature.
Add-on tests for Renin and Aldosterone should not be done on samples which have been previously collected or stored at 4 C.

Collection Requirements for both or either tests
Collect into 4 mL EDTA tubes at Room Temperature. Do not collect on ice
If both Renin and Aldosterone are requested together, they can be collected into the same EDTA tube
In the laboratory, spin and separate the plasma immediately. Plasma is stable at Room Temperature if analysis is performed on the same day.
Renin must be frozen at -80 C. Transport plasma at room temperature (Maroondah and Angliss) until it can be placed in -80 C Freezer.(Must be done within 3-4 hours).
Add-on tests for Renin and Aldosterone should not be done on samples which have been previously collected or stored at 4 C.
Renin will not be collected at Healesville Hospital and Yarra Ranges Health Collection Rooms.
Samples from Angliss and Maroondah must be collected within business hours to allow transport to Box Hill via courier. |

| Notes | Prior to testing, patients should be withdrawn from diuretics, ACE inhibitors, angiotensin II receptor antagonists, beta blockers and calcium channel blockers for 3 weeks. Patients should also be well hydrated, have had 7g/day of salt for one week and have normal plasma potassium and bicarbonate levels.
