MessagePatient Preparation: 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. Collect a full tube, following standard venipuncture techniques. Allow blood to clot at room temperature (20-26° C) and centrifuge immediately to separate the serum from the cells. Freeze as soon as possible.
