Panels that include this biomarker

  • Dementia Panel, Secondary Causes 34541

    3 analytes · Serum · Fasting not stated

    Method and collection
    Method
    See individual tests
    Preparation
    Fasting specimen is preferred. Specimen collection after fluorescein dye angiography should be delayed for at least 3 days. For patients on hemodialysis, specimen collection should be delayed for 2 weeks. According to the assay manufacturer Siemens: "Samples containing fluorescein can produce falsely depressed values when tested with the Advia Centaur TSH3 Ultra assay."
    Collection
    EDTA (lavender-top): Maintain specimen at room temperature. Do not refrigerate. If multiple draw, collect EDTA (lavender-top) tube last. Traumatic draw can introduce thromboplastin and trap WBC and platelets. Refrigeration can precipitate fibrin and trap WBC and platelets. Serum note: If transport to performing laboratory will exceed 24 hours please transport refrigerated (cold packs).

    Preparation
    Patients taking calcineurin inhibitors should stop their medication for 72 hours prior to draw. Specimen collection after fluorescein dye angiography should be delayed for at least 3 days. For patients on hemodialysis, specimen collection should be delayed for 2 weeks after angiography. According to the assay manufacturer Siemens: samples containing fluorescein can produce falsely depressed values. Dietary supplements containing biotin may interfere in assays and may skew results to be either falsely high or falsely low. For patients receiving the recommended daily doses of biotin, draw samples at least 8 hours following the last biotin supplementation. For patients on mega-doses of biotin supplements, draw samples at least 72 hours following the last biotin supplementation.

We compile this page from named laboratory catalogs, guidelines and studies. Labs calculate reference intervals from the people they test, for one assay method and one population group, so an interval describes that population rather than an optimal target.
