– Important Update –

Our Bellingham Airport location will be closed in honor of Memorial Day, Monday, May 30th.

The Northwest Laboratory location will maintain normal business hours to assist those with a doctor’s order or urgent testing requested by WCHD.

Northwest Laboratory is a national clinical laboratory offering high-volume, rapid turnaround COVID-19 testing services. We have been at the forefront of COVID-19 testing since the inception of the pandemic and have performed over 2 million COVID-19 RT-PCR tests to date.

As an added convenience, we offer drive-thru COVID testing to the community at the Bellingham Airport Community COVID-19 Testing Site. Scheduling a test at the airport site does not require an existing doctor’s order. The site is run in partnership with the Whatcom County Health Department, which monitors all testing and notification of positives. The county’s Health Officer is designated as the ordering physician.
