SARS-CoV-2 (IgG) Antibody Panel Saliva Collection

Spike Protein, N-Protein, Receptor Binding Domain

Consistency in collection methods and sample handling is recommended for optimal results. Production of volumes larger than 1 mL may produce a diluted sample that may necessitate a recollection.

Before Sample Collection

• Avoid foods with high sugar, acidity, or caffeine immediately before sample collection.
• Document consumption of prescription/over-the-counter medications within the prior 12 hours.
• Rinse mouth with water to remove food residue and then wait at least 10 minutes before collecting saliva.

During Sample Collection

• Recommended Collection Volume: 0.3 – 1 mL
  
• Use a collection device that has been validated for the measurement of this analyte.
• Follow your selected sample collection device/method protocol.

After Sample Collection

• Record the time and date of specimen collection.
• Refrigerate samples immediately (if possible) and freeze at or below -20°C (household freezer) when possible, until sample shipping.
• Do not add preservatives to saliva samples unless they have been previously validated with the assay.
• Consider aliqouting samples to avoid multiple freeze-thaws.
• If shipping temperature can be maintained below 22°C, ambient overnight shipping is acceptable. If temperatures may be encountered during shipping above 22°C, ship on cold packs, overnight.
