The SCAN study is now available for Pierce County residents. Sign up here for a free, at-home COVID-19 test.


The Greater Seattle Coronavirus Assessment Network (SCAN) is a research study investigating the coronavirus (COVID-19) outbreak in our region. SCAN supports public health leaders, including Public Health – Seattle & King County and Tacoma-Pierce County Health Department, with anonymized data to help public health leaders respond to the coronavirus (COVID-19) outbreak.

SCAN is working to support efforts to control coronavirus by providing public health leaders in the Greater Seattle region and researchers worldwide with information about how the virus is spreading in our community. SCAN connects experts in medicine, science, and public health from across Seattle and beyond to help protect our community.

Your participation in SCAN’s research will help us detect the spread of coronavirus. Regardless of whether you take part in SCAN, please help reduce the spread of coronavirus by following the latest guidelines from your state and local public health agencies. That includes washing your hands, working from home if you’re able, staying home if you feel sick, and contacting your doctor right away if you are severely ill.

Step 1 Healthy and sick people in the community take their own nasal swabs at home and return them them to SCAN’s research labs

Step 2 SCAN tests the samples for presence of a current coronavirus infection.

Step 3 People who have coronavirus detected in their swabs are contacted by a healthcare member of our research team. More detailed results will be available for participants via our secure results portal.

Step 4 Results are used to understand where and how many people are sick with coronavirus in our area. This information will guide data-driven public health recommendations and guidelines for protecting our community.
