Using a chilled 6-mL lavender-top (EDTA) tube taken from a Trasylol® kit, collect a whole blood specimen
Immediately following collection, mix the specimen several times by inverting the EDTA collection tube to prevent clotting
After removing the cap from the EDTA draw tube, take one of the sterile, Beral pipettes (from under the grey 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.
