Houston Health Department leading antibody testing survey to better understand the spread of COVID-19 in Houston

The Houston Health Department is collaborating with the Centers for Disease Control and Prevention, Rice University, and Baylor College of Medicine to conduct an antibody testing survey in two phases, with phase underway and phase two starting

The survey will identify people infected in the past 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 infection.

HHD staff and Houston Fire Department paramedics will visit randomly selected homes across Houston and ask household members to answer survey questions and provide a blood sample.

HHD Antibody Survey“If we knock on your door, I strongly encourage you and your loved ones to participate in this important survey,” Mayor Sylvester Turner said.

“The data you provide by participating will help inform strategies to mitigate the effects of COVID-19.” Only homes approached by the teams are eligible to participate, and participation is voluntary. For more information about the antibody survey, visit
