    Specimen Requirements


    Specimen

    Plasma, frozen


    Volume

    6 mL (3 mL for viral quantitation and 3 mL for reflex to PhenoSense Integrase®)


    Minimum Volume

    4 mL (Note: This volume does not allow for repeat testing.)


    Container

    Ship in two or more screw-cap polypropylene frozen transport tubes.


    Collection

    Collect specimen in lavender-top (EDTA) or PPT™ tubes. Do not use green-top (heparin) tubes. Centrifuge specimen within six hours of collection. Remove plasma, transfer plasma to screw-cap polypropylene transport tubes (not "pop-top" or "snap-cap"), and freeze. Ship frozen (preferred). Do not ship frozen in PPT™. If PPT™ is used to collect plasma, specimen must be transferred to screw-cap tubes prior to freezing to avoid false elevation of low viral load samples. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.


    Storage Instructions

    Freeze. Separate frozen sample required for PhenoSense Integrase® portion of the test. Frozen sample is preferred for the viral load assay but is also stable at room temperature for one day or refrigerated for five days. Freeze for long-term storage.


    Causes for Rejection

    Hemolysis; green-top (heparin) tube; specimen received in "pop-top" or "snap-cap" tube; quantity not sufficient for analysis; frozen PPT™
