Collection Instructions
MUST USE FUTHAN COLLECTION KIT Container/Tube; Lavender Top Tube Specimen: 1 mL Plasma, EDTA with Futhan preservative Transport Temperature: Frozen Collection Collect EDTA whole blood sample into a chilled lavender-top tube. Immediately add Futhan preservative as directed in the Futhan collection kit (LabCorp N° 78946). Recap lavender tube and invert several times to mix well. Centrifuge the whole blood specimen to separate the plasma. Transfer the plasma into the plastic screw-cap tube that is included in the collection kit. The specimen must be submitted in this transfer tube, which is labeled with the words "Futhan Added." Freeze immediately and maintain frozen until tested. Patient Preparation No radioactive isotopes administered within 48 hours prior to venipuncture.
Samples that are not properly collected and stored will produce erroneously elevated results due to in vitro activation. Blood must be drawn directly into tubes containing EDTA at a final concentration of at least 10 mM with the addition of nafamostat mesilate (Futhan, FUT-1750) to further reduce in vitro complement activation.
