SALEM — Oregon officials are scrutinizing a coronavirus testing company for possible violations of a law protecting consumers against deceptive business practices.

The Oregon Department of Justice launched a civil investigation into the Center for Covid Control last week — after media reports in Texas and Florida accused the company of faking lab results and not disclosing data to public health agencies.

One of two Oregonians who has lodged a formal consumer complaint about the company said staff working out of a tent in a southeast Portland convenience store parking lot in September gave her nasal swab kits for self-administered rapid and PCR tests.

The woman said when she got back to her car, she noticed the rapid test had expired months earlier.

The woman also complained that staff kept completed PCR tests, which must be sent away for laboratory testing, stowed in a crate left outdoors on a hot day.

The other complainant said she didn’t receive the results of a PCR test within 72 hours, as was advertised.

The Center for Covid Control lists more than 300 testing sites on its website, including two each in Portland and Salem and one in Tigard. Several visitors drove away empty-handed Tuesday after visiting the company’s site off Northeast Sandy Boulevard, where a makeshift sign taped to the graffiti-coated storefront stated: “sorry we are out of tests.”

“Let me be very clear — we are absolutely not conducting fake tests,” a company spokesperson said in a statement to Willamette Week, which first reported the investigation. “Our employees and the employees of our independent operators are risking their lives everyday to provide testing for patients.”

The company did not respond to questions from The Oregonian. The Oregon Health Authority did not immediately respond when asked if the company’s results were used in the state’s daily COVID-19 case counts.

The state Department of Justice investigation is probing for potential violations of the Unfair Trade Practices Act.
