Rochester General's Dr. Edward Walsh, an Infectious Disease Specialist explained the purpose of the testing.

"The main focus at this point is to identify how many people had relatively mild, or asymptomatic in the community," Dr. Walsh said. "We've been speculating that there are many more people who have been infected than we know about."

Walsh describes antibodies as a protein that's introduced into the body through a vaccine. This protein he says will produce many other antibodies in the bloodstream.

"These antibodies will bind to their target which is usually another protein. Usually, it's a protein from a pathogen that you don't want to be infected with," Walsh said.

The Doctor says right now the test is not 100% accurate, because it's brand new. A person who had their blood drawn can have either false positive, or negative for COVID-19. Results Walsh says can't be taken lightly.

"I wouldn't flagrantly run off knowing that I tested positive, and I have antibodies in my blood and hug everybody on the street because we don't know whether that would provide protection at this point," Walsh said.

He also went on to say it will take some time to find out.

The State's Department of Health said the testing survey will test 3,000 people from the State's total population of more than 19 million residents. This will help determine the percentage of the population that could be immune to the virus allowing more individuals to safely return to work.
