The same collections firm that exposed Quest Diagnostics’ patients has impacted fellow medical testing giant, LabCorp. A day following Quest’s announcement, LabCorp announced that 7.7 million consumers‘ names, addresses, dates of birth, and balance information were compromised.

On June 3rd, 2019, Quest Diagnostics disclosed a data breach impacting approximately 11.9 million people in a filing with the U.S. Securities and Exchange Commission. The leak exposed patients’ sensitive data, including financial accounts, Social Security numbers, and health insurance account information. The clinical laboratory is one of the largest in the industry, serving about half of all physicians and doctors in the U.S.

According to a Quest Diagnostics press release, the breach originated through one of Quest’s billing collections vendors, AMCA, who had its web payment system hacked from August 2018 to March 2019. The data in this system can be leveraged to commit identity theft and fraud.

AMCA has taken its web payment page offline and an investigation is ongoing, and it is not believed any lab tests results were included in the data exposed.
