The U.S. Centers for Disease Control has started using antibody blood tests to confirm coronavirus infections, even among those who have not developed symptoms, Politico reported.
The test scans for antibodies in a blood sample to confirm whether a person has been exposed to the coronavirus, The New York reported. The tests, called serology tests, can help confirm whether there have been populations of U.S. residents carrying the virus across the country.
Determining how many people who come into contact with the coronavirus and do not get sick is key to understanding the spread of the pandemic, according to Politico.
The tests will focus on three groups. The first group tested will be those who were not diagnosed with the coronavirus in hot spots where the disease has multiplied across the country. This would include areas like New York City, now the epicenter of the virus in the United States.
