PONTIAC, Mich. (AP) — Drive-thru COVID-19 testing locations in Oakland County are being relocated as colder weather sets in, while Wayne County has added testing sites.

In Oakland County, tests will be available on Mondays at the Old Holly fire station, Tuesdays at the Rochester fire station, Wednesdays at the Southfield City Hall employee parking deck and Thursdays at the Pontiac fire station.

The new testing locations will be open by appointment only and from 9 a.m. to 5 p.m. Tests are available for anyone age 4 years and older. Youth 17 and younger must exhibit COVID-19 symptoms and be a resident of Oakland County or attend school in the county.

There is no charge for the tests and no prescription is needed.

Free testing now is available at HYPE Athletics centers in Wayne County’s Dearborn Heights and Wayne. Both locations will be open from 9 a.m. to 7 p.m. Monday through Friday and from 9 a.m. to 3 p.m. on Saturdays.

The new locations were opened due to rising levels of the virus in Wayne County, officials said.

“Until vaccine is available, testing is the primary means to keep numbers down and the community safe,” said Carol Austerberry, Wayne County's public health officer. “We strongly encourage all residents to get tested frequently and to continue following all prevention measures.”
