Special Instructions The patient’s posture at the time of collection should be noted (see Patient Preparation). Specimen Plasma, frozen Volume 1 mL Minimum Volume 0.8 mL (Note: This volume does not allow for repeat testing.) Container Lavender-top (EDTA) tube Collection Draw blood into an EDTA tube. Keep tube at room temperature. Centrifuge at room temperature.1 Transfer the plasma into a LabCorp PP transpak frozen purple tube with screw cap (LabCorp N° 49482). Freeze immediately and maintain frozen until tested.
