Additional Technical Information

Ordering Recommendation

Use for the qualitative detection of IgG antibodies against the nucleocapsid protein of SARS-CoV-2 (COVID-19) that develop in response to natural infection with SARS-CoV-2. These antibodies do not develop as a result of a COVID-19 vaccination. There are no current recommendations for assessing COVID-19 vaccine response.

To reduce the likelihood of a false-positive result, the CDC Interim Guidelines for COVID-19 Antibody Testing suggest using an orthogonal testing algorithm so that individuals positive by one antibody test are retested with a second antibody test (refer to COVID-19 IgG by ELISA 3002723).
