Center for COVID Control under investigation after USA TODAY reporter starts asking questions

A nationwide chain of coronavirus testing sites known as the Center for COVID Control is facing increasing scrutiny as details emerge about the company and its primary laboratory, now under investigation by state and federal officials.

The company and its partner lab, Doctors Clinical Lab, provide "inaccurate and deceptive" test result information and have fraudulently reported negative test results, according to lawsuits from the attorneys general of Minnesota, Washington State and Oregon.

The Illinois-based Center for COVID Control launched in 2020 and, at its peak, was operating more than 300 testing sites across at least 26 states, processing about 80,000 tests a day, according to the company.

The sites have the lowest rating the Better Business Bureau can give a business, and dozens of people across 20 states have reported concerns about the sites to USA TODAY.

The company and lab are also under investigation by officials in Illinois and California and the Centers for Medicare and Medicaid Services, part of the U.S. Department of Health and Human Services. The FBI raided the headquarters of the company and lab in January.
