Used to aid in identifying individuals with a recent or prior infection.
In unvaccinated individuals, this assay will have a positive result post-infection (99% at ≥ 14 days).
In individuals vaccinated with mRNA or viral vector vaccines (e.g., BioNTech, Moderna), a positive test also suggests natural infection; however, if vaccinated with inactivated native virus vaccines (e.g., Sinovac), the test may be positive from the vaccine.
Note: Laboratory results should not be used solely to diagnose or exclude recent infections from COVID-19. You must consult your doctor, who will evaluate your clinical history, symptoms, vaccination status, and test results and interpret the results.
