Collection Requirements for both or either tests

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 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.
