SARS‑CoV‑2 Total Antibody, Spike, Semi‑Quantitative
Also known as: SARS, Coronavirus Total Antibody, Novel Coronavirus, COVID19, nCOV
Use
This test is intended as an aid in identifying individuals with an adaptive immune response to SARS‑CoV‑2, indicating recent or prior infection. Individuals vaccinated with a SARS‑CoV‑2 spike or receptor‑binding domain vaccine may test positive; the clinical significance of positivity in that context is unknown. The results of the semi‑quantitative test should not be interpreted as a measure of immunity or protection from reinfection, and the assay should not be used to diagnose acute SARS‑CoV‑2 infection.

Special Instructions
Not provided.
Limitations
Results should not be interpreted as indicating degree of immunity or protection from reinfection; positive results may occur post‑vaccination and their clinical significance is not established; not for diagnosis of acute infection.
