Specimen stability for the antibody test is as follows:

  • Room temperature: 5 days
  • Refrigerated (2 °C–8 °C): 7 days
  • Frozen (-20 °C): 7 days

Specimens should be transported refrigerated to Sonora Quest according to standard operating procedures. Cold packs/pouches must be used if placing specimens in a lockbox for courier pick-up. STAT pick-up cannot be ordered for this test. The COVID-19 antibody test does not need to be ordered on its own separate requisition.
