Houston Health Department’s COVID-19 antibody testing survey

The Houston Health Department announced a testing survey to understand how many people in the city were previously infected with the coronavirus.

HOUSTON — The Houston Health Department on Wednesday announced a COVID-19 antibody testing survey to better understand the spread of the virus in the city.

The survey, in collaboration with the CDC, Rice University and Baylor College of Medicine, will identify people previously infected with COVID-19 by the presence of antibodies, proteins the body’s immune system makes to fight infections. Antibody testing does not replace oral or nasal swab viral testing that looks for current COVID-19 infection.

Phase 1 is set to take place Sept. 8 to Sept.
