This test detects IgG antibodies to SARS-CoV-2, indicating a prior infection or immune response to vaccination. It measures antibodies to the spike protein, which are produced by both infection and most vaccines. While the presence of antibodies suggests some level of immunity, the exact level of protection they confer is still being studied.
Detects IgG antibodies to SARS-CoV-2. Distinguishes past infection from vaccine-only immunity using N-protein (infection-only) vs S-protein (both) antibodies. Useful for assessing prior exposure or vaccine response in immunocompromised patients.
Anyone curious about past asymptomatic COVID infection, immunocompromised patients evaluating vaccine response, post-COVID convalescent plasma donors, anyone investigating Long COVID symptoms.
