Quest Diagnostics, the New Jersey-based blood testing providers in the country, filed a report with securities regulators, specifying that nearly 12 million of its customers may have had medical, financial, and personal information (inlcuding Social Security numbers) breached.
Quest, one of the largest laboratories in the US, said it was notified that between Aug. 1, 2018 and March 30, 2019, someone had unauthorized access to the systems of AMCA, a billing collections vendor. AMCA had 11.9 million of Quest’s patients records stored on the affected AMCA system. Quest said it has not received “detailed or complete” information from AMCA about the breach yet.
“Quest Diagnostics takes this matter very seriously and is committed to the privacy and security of patients’ personal, medical and financial information,” the company added in the filing. “We are committed to keeping our patients, health care providers, and all relevant parties informed as we learn more.”
