CDC Issues Guidelines for COVID-19 Antibody Testing
June 2, 2020
Serologic testing for SARS-CoV-2 (the virus that causes COVID-19) has received Emergency Use Authorization from the U.S. Food and Drug Administration, but many questions still remain about the efficacy of antibody testing. It can help determine whether an individual was ever infected with the coronavirus, which can aid scientists in understanding the spread of the virus and identifying patients whose donated blood plasma may help treat current COVID-19 patients. But limitations of the tests themselves and a lack of data regarding these patients’ potential immunity mean that a strategic approach to serologic testing is critically important.
The U.S. Centers for Disease Control and Prevention (CDC) has issued interim guidelines for COVID-19 antibody testing that address the use of serologic tests to determine immunity and infectiousness among patients recently infected with the coronavirus. These guidelines discuss the current status of antibody testing in the United States, offer information about how to optimize testing outcomes, and provide overall recommendations for the use of serologic tests.
Healthcare professionals and facilities who use these tests should consult these guidelines and check back often for updated recommendations.
