Result Interpretation

This test has not been reviewed by the FDA. It has been validated to be accurate

by Northwell Health Laboratories.

Negative results do not rule out SARS-CoV-2 infection, particularly in those

who have been in contact with the virus. Follow-up testing with a molecular

diagnostic 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-CoV-2 infection or to inform infection status.

Positive results may rarely be due to past or present infection with non-SARS-CoV-2 coronavirus strains, such as coronavirus HKU1, NL63, OC43, or 229E.

Northwell Health Laboratories, through extensive validation testing, has confirmed that this risk is minimal with this test
