Can I Go To Work If I Received A Positive Covid-19 Antibody Test Result

Does an antibody test diagnose an active COVID-19?

Antibodies can take several days or weeks to develop after you have an infection and may stay in your blood for several weeks after recovery. Because of this, antibody tests should not be used to diagnose an active coronavirus infection.

How long after getting infected will COVID-19 antibodies show up in the test?

An antibody test may not show if you have a current infection because it can take 1–3 weeks after the infection for your body to make antibodies.

What should be done if the COVID-19 antigen test result is positive?

In a community setting, when testing a person who has symptoms compatible with COVID-19, the healthcare provider generally can interpret a positive antigen test to indicate that the person is infected with SARS-CoV-2; this person should follow CDC's guidance for isolation. However, if the person who has received a positive antigen test result is fully vaccinated, the healthcare provider should inform the public health authorities. Ideally, a separate specimen would be collected and sent to a lab

Will I be able to return to work without having an antibody test for COVID-19 done?

The requirements for returning to work may be determined by your employer or your state and local governments. Ask your employer about your workplace's criteria for returning to work and any actions your employer will be taking to prevent or reduce the spread of COVID-19 among employees and customers.
