Quantitative Liquid Chromatography/Tandem Mass Spectrometry |
| SPECIMEN REQUIREMENTS | ||||
|---|---|---|---|---|
| Specimen | Specimen Volume (min) | Specimen Type | Specimen Container | Transport Environment |
| Preferred | 0.5 mL (0.15 mL) | Plasma | Sodium Heparin (Green Top / No-Gel) | Frozen |
| Alternate 1 | 0.5 mL (0.15 mL) | Plasma | Lithium Heparin PST (Light Green Top) | Frozen |
| Instructions | Notes: 0.15 mL (Note: This volume Does not allow for repeat testing.) Specimen Type: PREFERRED: Frozen plasma from green-top (sodium heparin) tube. ACCEPTABLE: Frozen plasma from green-top (lithium heparin) tube, frozen plasma from lavender-top (EDTA) tube or frozen plasma from PPT(TM). Frozen serum from serum separator tube (SST) or frozen serum from red-top tube will not be rejected. NOTE: Plasma reference ranges will be applied to all specimen types. Specimen Storage: Centrifuge, remove plasma from cells, and FREEZE immediately. Specimen Collection: Separate plasma from cells. Transfer specimen to plastic transport tube before freezing. To avoid delays in turnaround time when requesting multiple tests on frozen samples, PLEASE SUBMIT SEPARATE FROZEN SPECIMENS FOR EACH TEST REQUESTED. Specimen Stability: Ambient: Unstable, Refrigerated : Unstable, Frozen: 14 days |
