COVID-19 Daily Antibody Tests (2021)

Data from the Texas Department of Health and Human Services shows the number of antibody tests performed daily in 2021 and how many of those tests were positive.

An antibody test determines whether someone has had COVID-19 through the presence of antibodies and indicates they may have some immunity.

Due to the winter storm that began in Texas on Feb. 14 reporting data for that week was inconsistent, leading to a sharp rise in numbers when reporting resumed Feb. 21.
