In the US, they began testing for antibodies to coronavirus. About this writes ScienceAlert with reference to representatives of the US government.
The new antibody detection tests are based on serological studies that differ from nasal swabs currently used to determine the presence of the virus. Using these tests, you can find out if certain antibodies are present in the patient’s blood, which the immune system produces in the fight against coronavirus.
Mass antibody testing will allow you to find out the exact number of coronavirus infected in the country who have had COVID-19 without symptoms. In addition, the analysis will gradually remove quarantine in the country, attracting people with immunity to coronavirus infection to work.
At the same time, people with negative tests for coronavirus are being tested in experimental mode.
Today, the United States is the center of the spread of coronavirus infection in the world. The country has already recorded 370 thousand patients with COVID-19, of which 11 thousand died and 20 thousand recovered.
