On-Site COVID-19 Testing

The Lab is offering free voluntary COVID-19 testing weekly to asymptomatic employees and affiliates working at Lab locations.


Getting a COVID-19 test is a great way to protect you, your family, and your co-workers by identifying COVID-19 infections early. This allows infected workers to seek health care early, self isolate to protect others, and help identify others who may be infected through contact tracing.


Testing is available at either the Lab’s cafeteria on Mondays and Tuesdays from 11 a.m. to 1 p.m. or at the Potter Street patio on Wednesdays between 11 a.m. and 1 p.m. Once your appointment is made, show up for your appointment location, check in with the health care professional, get a quick nasal swab, and receive your results within 48 hours.


The Lab hired a local company, BasisDX to provide COVID-19 testing services. All testing is conducted under strict CLIA standards.


So far, the COVID-19 testing has uncovered three cases of COVID-19, all asymptomatic. Those people were sent home and counseled to talk with their personal health care professional. As of Feb. 22, there have been 946 COVID-19 tests of Lab personnel, with 483 unique employees tested since the on-site testing program began.


Teleworkers who need to be tested should use a community testing site or consult with their personal health care provider.

On-site workers who are ill or have been in close contact with someone who is symptomatic for COVID-19 should not come on site and should contact their personal health care provider for testing and follow-up care.
