Interpretive Data
Negative or Positive
This antibody can be useful in detecting immunity developed due to SARS-CoV2 infection OR after vaccination OR monoclonal antibody treatment. IgG antibodies can be detected in most patients 2 weeks post symptom onset or post vaccination.
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.
