Renin must be frozen at -80 C. Transport plasma at room temperature (Maroondah and Angliss) until it can be place in -80 C Freezer.(Must be done within 3-4 hors).

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.

Prior to testing, patients should be withdrawn from diuretics, ACE inhibitors, angiotensin II receptor antagonists, beta blockers and calcium channel blockers for 3 weeks.
