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.
