Renin Activity, Plasma
Collect: Lavender (EDTA) - 1 ml plasma.
Specimen Preparation : Draw blood into an EDTA tube. Keep tube at room temperature. Centrifuge at room temperature. Transfer the plasma into a LabCorp PP transpak frozen purple tube with screw cap . Freeze immediately and maintain frozen until tested. It is critical that the plasma be transferred and frozen as quickly as possible to prevent cryoactivation of protein to renin (which results in falsely elevated renin levels). To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.
Storage/Transport Temperature: CRITICAL FROZEN.Causes for Rejection: Gross hemolysis; serum or heparinized plasma specimen; specimen not received frozen; recently administered isotopes
Stability : Room Temperature/Refrigerated: Unacceptable; Frozen: 14 days
