Collect: One 6.0 mL SST (Gold) tube, One 6.0 PST (lithium or sodium heparin) 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)
After separation from cells: Ambient: 24hours; Refrigerated: 7days; Frozen: 1 year (avoid more than 7 freeze/thaw cycles)
Performed
Microbiology/Serology Daily
Remarks
To aliquot: Centrifuge the sample and transfer the serum into a clean tube.
Notes
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).
