Reference Interval

Negative

Interpretive Data

Negative or Positive
This test has been authorized by the FDA under an Emergency Use Authorization (EUA).  Negative results do not rule out SARS-CoV2 infection, particularly in those who have been in contact with the virus.  Follow-up testing with a molecular diagnositic test should be considered to rule out infection in these individuals.  Results from antibody testing should not be used as the sole basis to diagnose or exclude SARS-CoV2 infection or to inform infection status.  

Positive results may be due to past or present infection with non-SARS CoV2 coronavirus strains such as cornovirus HKU1, NL63, OC43, or 229E.

This test should not be used to screen donated blood.
