A document with the patient assessment questions can be accessed here. Please print, complete, and attach this document to Cleveland HeartLab requisition forms when ordering COVID-19 testing.

Reference Range:
| Analyte | Interpretation |
|---|---|
| SARS-CoV-2 Ab (IgG), Nucleocapsid, Qualitative | Negative |
NOTE: This test has not been reviewed by the FDA. 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 be due to past or present infection with non-SARS-CoV-2 coronavirus strains, such as coronavirus HKU1, NL63, OC43, or 229E.
Clinical Significance: This test is intended as an aid in identifying individuals with antibodies to SARS-CoV-2. A positive result indicates an immune response to a recent or prior infection with SARS-CoV-2. This test would not be expected to detect an immune response to a spike vaccine. It is unknown for how long antibodies persist following infection or if the presence of antibodies confers protective immunity. This assay should not be used to diagnose acute SARS-CoV-2 infection.
