L022
Renin Activity, Plasma
| Methodology: | Radioimmunoassay (RIA) |
| Performed: | Varies |
| Reported: | 5-6 days |
| Specimen Required: |
Collect: Lavender (EDTA) - 1 ml plasma. Patient Preparation: In order to facilitate interpretation of test results, the patient should be taken off medications for at least three weeks prior to sample collection. Dietary sodium levels during the period prior to testing can affect renin levels.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 isotopesStability : Room Temperature/Refrigerated: Unacceptable; Frozen: 14 days Note: This test is approved for NY .Performing Lab
