This test measures antibodies to SARS-CoV-2 nucleocapsid (N) protein in order to help identify individuals with an adaptive immune response to SARS-CoV-2, indicating recent or prior infection. Does not detect antibodies from currently available SARS-CoV-2 vaccines. Also measures SARS-CoV-2 Semi-Quant Total Antibody, Spike used to determine an adaptive immune response to SARS-CoV-2/COVID-19 indicating recent or prior infection.
Please note this test measures the same items as SARS-CoV-2 Antibodies, Nucleocapsid and SARS-CoV-2 Semi-Quantitative Total Antibody, Spike.
For limitations and further information, please see the LabCorp page for this test.
Note from LabCorp: These tests have not been FDA cleared or approved. These tests have been authorized by FDA under an Emergency Use Authorization (EUA).
Expected turnaround is within 1-3 days, although this may vary depending on other tests ordered for the same blood draw, and expected variation with LabCorp testing.
