Test Code COVSQ Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), Spike Antibody, Semi-Quantitative, Serum
Ordering Guidance
This test will detect antibodies developed due to prior or current infection and will detect antibodies against the spike glycoprotein of SARS-CoV-2 generated following vaccination. This test will not differentiate between the two events. The absence of antibodies in this assay does not rule out recent infection.
For confirmation of prior infection in the presence of vaccination, order COVTA / Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-Cov-2), Nucleocapsid, Total Antibody, Serum.
Molecular testing is recommended for diagnosis of COVID-19 in symptomatic patients. For more information see HPCOV / Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Molecular Detection, Varies.
