Specimen Requirements
Specimen
Plasma with Trasylol®, frozen
Volume
2 mL
Minimum Volume
0.3 mL
Container
Lavender-top (EDTA) tube
Collection
Trasylol® kits may be ordered through the PeopleSoft system (LabCorp N° 33328). Using a chilled 6-mL lavender-top (EDTA) tube taken from the kit, collect a whole blood specimen. Mix the specimen several times by inverting the EDTA collection tube. After removing the cap from the EDTA draw tube, take one of the sterile, Beral pipettes (from under the gray foam), and add 0.25 mL Trasylol® to the EDTA tube. Recap the EDTA tube and invert several times to mix well. Centrifuge the EDTA tube to separate the plasma from the cells, and immediately transfer the plasma into one of the brown screw-cap transfer tubes provided in the kit. There should be a "Trasylol® Added" label affixed to the brown transfer tubes. Cap and freeze the labeled transfer tube containing the EDTA plasma with Trasylol® added. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.
