antibody testing

Two types of testing for the virus that causes COVID-19 are increasingly accessible in the Rochester area.

One is the test that looks for the virus, allowing doctors to diagnose whether a person is currently infected. The other searches for antibodies, which indicate whether a person was already exposed and fought the virus off.

Both hospital systems in the Rochester area say they now have more supply than demand for their coronavirus lab tests. Gov. Andrew Cuomo said supply was outpacing demand across New York state, and last week the state health department expanded its guidance for who should be tested.

Andy Ophardt, who manages a primary care clinic in Brighton, said he used to field frequent questions from patients asking about how to get tested for the virus. He had to call testing sites to confirm that people his office referred met an exacting set of criteria.

The New York state health department has been testing shoppers at the East Avenue Wegmans store as part of an effort to gauge the prevalence of the novel coronavirus in New York.

The Rochester Wegmans is one of “approximately 20” grocery stores across the state where the health department said it’s collecting blood samples from volunteers to see if they have been exposed to the virus that causes COVID-19.

The health department said it will collect samples from about 150 people at each testing site.
