Just as states, schools and other governing bodies are making decisions about rules regarding COVID-19 testing, the U.S. Centers for Disease Control and Prevention has posted on its website that antibody tests are not accurate enough yet to use in making policy decisions.
Depending on the setting and rates of infection in certain areas of the country, these tests could deliver both a false-negative and false-positive result, the CDC says. Plus, “some tests may exhibit cross-reactivity with other coronaviruses, such as those that cause the common cold,” which could then result in a false-positive test.
