One 6.0 mL SST (Gold) tube or One PST tube or One 5.0 mL EDTA (Lavender) tube.
2 mL serum or plasma (Min: 1.0 mL).
Storage/Transport Temperature
Refrigerated. If sample transport to the lab is not the same day as collected; aliquot the serum or plasma.
Stability (from collection to initiation)
Stability: After separation from cells: Ambient: <8 hours; Refrigerated: 14 days if pour off serum, 72 hours if gel serum; Frozen: 1 year (avoid more than 6 freeze/thaw cycles)
Performed
Serology/Microbiology. Daily.
Remarks
To aliquot: Centrifuge the sample and transfer the serum into a clean tube.
Notes
Report comment: Weakly reactive samples will be confirmed by neutralization. Specimen in positive range: Confirmatory testing is recommended on all reactive (positive) samples collected for prenatal screening. If patient fits this criteria, please call Regional Pathology Services to request confirmatory testing. Confirmation by Neutralization will be sent to ARUP Laboratories (#0020128).
Biotin interference: Serum samples spiked with 10 ng/mL of biotin demonstrated <= 10% change in qualitative result.
Biotin Therapy may invalidate results. Some assays may exhibit interference when samples are collected from patients consuminghigher than recommended doses of biotin or supplements(including prenatal multivitamins),which also contain biotin. Simple daily supplementation, recommended dosage, is not problematic.It is recommended that all patients be asked if they are consuming high-dose biotin or biotin containing supplements. Patients should be cautioned to stop using biotin-containing supplements at least 72 hours prior testing.
