COVID-19 animation: Coronavirus and antibody testing explained
Показать описание
There are two kinds of tests for viruses like COVID-19. One tests for the presence of the virus in the sample, and the other for antibodies to the virus. Both are important for understanding who is infected and might transmit the virus to others, who have had the virus and might now be immune, and even who might potentially help others with treatment.
