Quest Diagnostics is launching a coronavirus antibody test for the general public to help people learn if they’ve been exposed to COVID-19 and developed antibodies against it, the company announced on Tuesday.

People — without even visiting a doctor — can buy this $119 test online. A doctor then reviews each test request.

If the test is approved, the person will get their blood drawn at one of Quest’s 2,200 patient service centers in the U.S.

Local Quest patient centers are in Boston, Brookline, Quincy, Arlington, Melrose, Waltham, Danvers, Braintree, Weymouth, Norwood, Lowell, Andover and Chelmsford.

Test results will be available in one to two days.

“With the introduction of this test and service, Quest is making it easy for people to access quality testing for antibodies to the virus which causes COVID-19, with access to physician interpretation and steering into needed care,” Jay Wohlgemuth, senior VP and chief medical officer for Quest, said in a statement.

“While the science on COVID-19 is evolving, testing for antibodies may identify people who have likely been exposed to COVID-19 and might have mounted an immune response to the virus,” he said. “Our goal is to empower individuals and their physicians to make informed decisions about their risk of infection and of spreading the virus.”

The new service broadens access to coronavirus antibody testing in the U.S. Last week, Quest announced the launch of its COVID-19 antibody test service for healthcare providers to order on behalf of patients.

Now with this QuestDirect service, a person can request the test and purchase it online. People can speak with a licensed physician about their results, which will be available on MyQuest, the company’s secure patient online portal.

Questions remain about coronavirus antibodies. It’s still unknown whether the development of antibodies provides protection from re-infection, or how long such protection lasts.

Before getting an antibody test, people should be symptom-free of COVID-19 for at least 10 days. They should wear a face mask at the Quest patient service center, and will need to pass a contact-less temperature check.

Antibody testing is not intended for people with an active COVID-19 infection. Patients who believe they may have COVID-19 should contact their healthcare provider.
