It may also mean that you have some immunity. Early results from antibody testing in Colorado suggest far more people have been infected with the novel coronavirus than recorded confirmed cases account for, thus drastically dropping the estimated fatality rate of COVID-19, analysis from Reason argued Wednesday. Science’s COVID-19 reporting is supported by the Pulitzer Center. The results are valuable for a number of reasons. As the United States and much of the world move toward relaxing shelter-in-place restrictions to let people move about more freely, public health experts hope to rely on antibody tests to determine who has been infected with the COVID-19 virus and may be immune — at least temporarily — and who is still susceptible. Antibody surveys suggesting vast undercount of coronavirus infections may be unreliable. If test results show that you have antibodies, it indicates that you were likely infected with COVID-19 at some time in the past.

Antibody testing will help health experts better assess how many people contracted the novel coronavirus. Antibody tests could be key to reopening the country. Here's how they work.

An antibody test is often described as the “have you had it?” test, as it reveals whether a person has had the coronavirus. Healthcare professionals can now order COVID-19 antibody serology testing using test code 39504.. The early results of USC/Los Angeles County antibody testing show a surprising number of residents have been infected with COVID-19. The SARS-CoV-2 (COVID19) antibodies, Immunoassay test is a qualitative (IgG) immunoglobulin test to detect antibodies to the SARS-CoV-2 virus in the blood. IgG antibody testing must be ordered by a physician.
