The new testing sites will use self-swab tests overseen by Rite Aid pharmacists. Testing is open to all adults 18 years of age or older, regardless if the person is showing symptoms, the chain said.
Registration is required and a time slot to be tested can be scheduled on Rite Aid's website.
Results are expected in three to five days, a company spokesperson said. Tests will be done weekdays from 10 a.m. to 8 p.m. and weekends from 10 a.m. to 5 p.m.

Rite Aid stated the expansion increases the number of its testing sites nationwide to 258.
The opening of the sites comes as California's surging virus caseload has left testing supplies short and lengthened the wait time for results.
The state revamped its guidelines for COVID-19 testing to focus on those in hospitals or considered at high risk of infection as the surging pandemic strains testing capacity.
In the next few weeks, Los Angeles County plans to aggressively expand coronavirus testing capacity by 65%. Their focus will be hot spots, including Montebello, South Gate, Panorama City, Downey, Norwalk and Compton. There will also be more testing in Bellflower, Pomona, El Monte and East L.A.
