CHICAGO – A nationwide coronavirus testing company under investigation by the Oregon Department of Justice and which has drawn criticism from customers in several states announced on Thursday a “one-week pause on all operations.”

The pause was expected to take effect Friday through Jan. 21 at all Center for COVID Control testing sites. The Illinois-based company’s website says it has more than 300 locations in the U.S. across several states. Two of those, Massachusetts and Washington, took action this week to shut down several of the company’s COVID testing centers in their communities.

In a company email addressed to “all location owners and managers” and obtained by USA TODAY, the Center for COVID Control cited “increased scrutiny by the media into the operations of our collection sites” over the past week.

“This, coupled with various customer complaints, resulted in various state health departments and even Department of Justice taking a keen interest in our company,” the notice said.

The company officially confirmed the week-long pause in a press release, saying “unusually high patient demand has stressed staffing resources.”

“Center for Covid Control is committed to serving our patients in the safest, most accurate and most compliant manner. Regrettably, due to our rapid growth and the unprecedented recent demand for testing, we haven’t been able to meet all our commitments,” Aleya Siyaj, the company’s founder and CEO, said in the release.

Company spokesperson Russ Keene did not immediately verify the authenticity of the internal memo that was sent to employees.

The news of the weeklong pause comes after the Oregon Department of Justice opened a civil investigation into the Center for COVID Control this week on suspicion of Unfair Trade Practices Act violations, spokeswoman Kristina Edmunson said.

At least two people filed complaints about the sites to the Oregon Justice Department late last year, Edmunson said. Since USA TODAY reported on the company last week, another ten people have filed complaints, Edmunson said. 

In Massachusetts, the Department of Public Health, in conjunction with the U.S. Centers for Medicare and Medicaid Services, issued cease and desist letters to three Center for COVID Control locations Wednesday, spokesperson Ann Scales said.

“Residents are urged not to visit the Center for COVID Control for a COVID-19 test,” Scales said.

The sites in Needham, North Dartmouth and Worcester were performing tests “without the required state approvals” and were ordered to “immediately cease providing all services that require clinical laboratory licensure,” Scales said.

Illinois has received seven complaints about the sites, the Illinois Attorney General’s Office said. Washington State has received two, according to the Washington State Attorney General’s Office.

On Wednesday, the city of Lakewood, Washington, shut down a Center for COVID Control testing site operating without a business license and notified local and state authorities, according to a press release.

“The City has no present knowledge of impropriety at this location beyond operation without a business license,” the release said. “The Washington State Department of Health and the Office of the Attorney General are both aware of national interest in the business.”

Meanwhile, a coalition of regional offices with the nonprofit Better Business Bureau is also looking into the company.

“Center for Covid Control has the lowest grade the BBB can give a business as well as the lowest customer review rating,” Thomas Johnson, spokesperson for the BBB of Chicago and Northern Illinois, told USA TODAY.

According to Johnson, people reporting to the BBB allege they did not receive test results, received incorrect test results or paid money for expedited results that were not delivered. They allege the company is “asking for a lot of personal information” and not responding to customers with questions about their test results, Johnson said.

Dozens of people nationwide, including test-takers and present and former employees, have reached out to USA TODAY expressing concerns about the company’s practices.

In the internal notice to employees, the Center for COVID Control said the complaints were “hyperbolized.”

“While many of the accusations against us may be hyperbolized, there are definitely areas that we need to improve on. We need to do better in ensuring our sites are compliant, our staff properly trained and above all, we need to ensure we are conducting and reporting each test accurately,” the memo said.

“This will not be time off for any of us. During the ‘pause’ period, we need to work together to complete all compliance trainings, get all our documentation up to date, procure site-specific CLIA waivers and more,” the memo said.

The company was expected to host a one-hour webinar Thursday afternoon.

“Enforcing this ‘pause’ is something that needs to be done to protect the interest of all of us — it is essential for our mutual survivorship,” the memo said.

A Twitter account tied to the company’s website was suspended Wednesday. Twitter representatives contacted Wednesday and Thursday did not immediately offer comment on why.

Christina Weber, 31, of Minneapolis, told USA TODAY she reported a Center for COVID Control testing site to local officials and was later contacted by an investigator for the Minnesota Attorney General’s Office, who informed her she was not the first to report a complaint with the site.

The office was unable to confirm or deny the existence of complaints or investigations under the Minnesota Government Data Practices Act, said John Stiles, deputy chief of staff for Minnesota Attorney General Keith Ellison.

In Florida, one family who filled out an online form for the Center for COVID Control received their test results while still waiting in line to take the test, WINK-TV reported. USA TODAY could not immediately verify the report.
