Test Details
Methodology
High-pressure liquid chromatography/tandem mass spectrometry (HPLC/MS-MS)
Result Turnaround Time
8 - 12 days
Special Instructions
Add aprotinin (Trasylol®) to all specimens to allow for analyte stability. Separate plasma immediately, store, and ship frozen.
Specimen Requirements
Specimen
Plasma with aprotinin (Trasylol®), frozen
Volume
1 mL
Minimum Volume
0.5 mL (Note: This volume does not allow for repeat testing.)
Container
Trasylol® collection kit (Obtain N° 33328 through LabCorp branch locations.)
Storage Instructions
Freeze.
Causes for Rejection
Thawed or nonfrozen specimen; specimen type other than EDTA plasma
Collection Instructions
Using a chilled lavender-top (EDTA) tube, collect a whole blood specimen, add 0.25 mL of Trasylol® to the tube and mix well. Centrifuge the sample and remove the plasma. Freeze immediately. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.
