SARS CoV 2 Nucleocapsid Antibody, IgG

The Abbott Architect SARS-CoV-2 IgG assay, run under an emergency use authorization from the FDA, is a qualitative test designed to detect IgG antibodies to the nucleocapsid protein of SARS-CoV-2 in serum and plasma from patients who are suspected of past coronavirus disease (COVID-19) or in serum and plasma of subjects that may have been infected by SARS-CoV-2.

Reactive (Positive) results may be due to past or present infection with SARS-CoV-2. 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.

Nonreactive (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.
