Instructions for Collection and Transport
Centrifuge specimen ASAP. Specimen should be centrifuged within 2 hours of collection if not collected in a grey top tube. For specimens needing transport to a central lab, if collected in a non-gel grey top tube, aliquot plasma into plastic vial after centrifugation. Transport refrigerated on freeze packs. If holding overnight, aliquot serum/plasma from the clot/gel into plastic vial and refrigerate.
Home Health agencies: Transport to laboratory within 2 hours of collection for centrifguation if not collected in a grey top tube since glucose in whole blood specimens is subject to degradation if not stabilized in sodium fluoride.
