As cases skyrocket, new free COVID-19 test site at Highline College expands testing capacity


A new free COVID-19 test site will open at Highline College on Friday, November 20. This new site complements free test sites already in operation in Renton, Auburn, Tukwila and Federal Way, increasing access to testing across south King County as cases skyrocket.


Expansion of testing in hard-hit south King County

Starting this week, south King County will have a new option for convenient, free COVID-19 testing. A new site at Highline College in Des Moines will expand efforts to control the spread of COVID-19 in a disproportionately affected region of King County. These sites are free and open to anyone, regardless of insurance or immigration status.

If you have COVID-like symptoms or have had close contact with someone with COVID-19, Public Health – Seattle & King County urges you to avoid contact with others and get tested immediately. Stay home and away from others while you are waiting for test results.

The new test site is located at Highline Community College, 2402 S. 240th St, Des Moines, in the South Parking Lot. Testing is provided at a walk-up tent. Free parking is available, as well as access to the 156 bus line.

The test site will be open Monday through Saturday, 9:30 am - 5:30 pm, beginning Friday, November 20. People are encouraged, but not required, to register for a testing appointment. Visit for scheduling and registration. Visit to see information on all free testing sites, including Highline College.

The testing site will be operated by CHI Franciscan and hosted by Highline College, with support from King County.

Increasing resources where cases are highest

South King County has the highest rate of positive tests in the county. Addressing those disparities is one of Public Health - Seattle & King County’s highest priorities during the COVID-19 pandemic.

Neighborhoods in south King County continue to experience the highest positivity rates in the region, and we must do everything possible to reverse the current trend of record-breaking case counts before our essential workers – including doctors and nurses – can no longer perform their duties," says King County Executive Dow Constantine.

"Along with masks and social distancing, getting tested is a big part of our response, and I want to thank Highline College and all our partners for helping to set up this new testing site. Thanksgiving will be different, but if everyone does their part, we can make sure all our loved ones stay safe and can celebrate together when the danger has passed."

Support for isolation and quarantine

Anyone who tests positive should isolate immediately. For those without a safe place to do so, King County isolation and quarantine sites are available to help people through a difficult situation and reduce risk of transmission. This is especially important for those living with a family member who is elderly or medically fragile, or people experiencing homelessness. Call the King County COVID-19 Call Center (206) 477-3977 to see if isolation and quarantine services are right for you.

If you need help with registration, call the King County COVID-19 Call Center (open seven days a week, 8 a.m. - 7 p.m.), at (206) 477-3977.
