New Serial Screening Path Makes It Possible For Prompt Testing Cases For Eua Tests.
To put it simply, the tests find the body's immune feedback to the infection caused by the virus instead of detecting the virus itself. In the early days of an infection when the body's immune reaction is still developing, antibodies might not be found. This restricts the examination's efficiency for identifying COVID-19, and also this is one reason serology examinations should not be made use of as the sole basis to diagnose COVID-19. Serology examinations might play a role in the battle versus COVID-19 by helping medical care specialists identify people that may have developed an immune feedback to SARS-CoV-2. Furthermore, these test results can assist in determining that may donate a component of their blood called convalescent plasma, which may work as a possible treatment for those who are seriously ill from COVID-19. Nevertheless, to use serology examinations appropriately, it is essential to comprehend their performance features and restrictions.
