Quest Diagnostics said it has learned of unauthorized access to its Quanum LSM system, which some clients use to place test orders, receive and look up results.

While the full scope of unauthorized access remains under investigation, at this time Quest believes an unauthorized party accessed certain patient records

The company disclosed in a Oct. 22 filing with the U.S. Securities and Exchange Commission that it learned of the incident on Oct. 21 and has notified federal law enforcement authorities and initiated cybersecurity incident response procedures. This incident has not materially disrupted the company’s business operations, Quest Diagnostics said.

The breach adds to a growing number of cyberattacks on the healthcare sector, including those on medical device makers Abbott, Stryker, Medtronic and Boston Scientific.
