COVID-19: New research looks for antibodies in blood donors

When someone has their antibodies virus, means that at some point he was infected with it. At the moment, the tests may not be at their best, but many people want to do them, especially those who think they have COVID-19, but couldn't control it when they got sick.

When someone donates their blood to the Red Cross, they agree to use a sample of it in the investigations of COVID-19.

People who want to donate blood should be absolutely healthy, while there may be a gap from the time they are no longer sick until they are involved in the research, because COVID-19 is still present in the body.
