DAYTON, Ohio - Do you wonder if you've had COVID-19? With many people asymptomatic, no one knows for sure without an antibody blood test. Beginning Monday, Nov. 9 Community Blood Center is now testing all blood donations for COVID-19 antibodies.

CBC is showing appreciation to blood donors by providing COVID-19 antibody testing at no cost through the end of the year. The new effort is to better help understand the spread of the virus among the population.

It is not a test to determine if someone has an active case of COVID-19. The test is an indicator of someone's exposure to coronavirus but is not to be considered as proof of immunity.

COVID-19 antibody testing will be used to identify those who are eligible to donate COVID-19 Convalescent Plasma (CCP) for critically ill COVID-19 patients. CCP is helping patients survive COVID-19, and demand is high with cases increasing this fall and concerns about more infections this winter.

"Identifying donors with the antibodies will help us build our supply of convalescent plasma and give area hospitals the ability to treat COVID-19 patients for many months to come," said CBC Medical Director Dr. James Alexander.

Samples of antibody tests of the population can help public health officials fight COVID-19 by calculating the percentage of the population that has already been infected.

CBC is testing all blood, platelet and plasma donations for COVID-19 antibodies. CBC is providing an initial test, followed up by a supplemental test for those who qualify, to help identify donors who could help COVID-19 patients by becoming future convalescent plasma donors.
