Testing for COVID-19 Antibodies

LabCorp announced on April 22, 2020, that COVID-19 serological antibody testing was being made more broadly available to hospitals, healthcare organizations, and through its patient service centers, including LabCorp at Walgreens locations.

Serology testing, also known as coronavirus antibody tests, can check for different types of antibodies developed after exposure to the SARS-CoV-2 virus that causes COVID-19. This type of COVID-19 test is for individuals who think they may have previously had COVID-19 and do not currently have symptoms. Note: antibody testing should not be used as the sole basis to diagnose or exclude infection. 

There are also several telehealth providers that offer access to COVID-19 antibody testing without having to go into a doctor’s office or visiting another healthcare provider. LabCorp has provided more information about telemedicine providers that can order tests from LabCorp.
