It was the largest qui tam (whistleblower) settlement paid by a medical laboratory for manufacturing and distributing a faulty product. In May 2011, Quest paid $241 million to the state of California to settle a False Claims Act case that alleged the company had overcharged Medi-Cal, the state's Medicaid program, and provided illegal kickbacks as incentives for healthcare providers to use Quest labs. In 2018, Quest Diagnostics was among a number of U.S.–based laboratories linked to inaccuracies of over 200 women's cervical smear tests for CervicalCheck, Ireland's national screening program. Audits of the testing performed by Quest (and another subcontractor, Clinical Pathology Laboratories, Inc. of Austin, Texas) showed a high rate of errors in analysis of samples which led to lawsuits and a government inquiry. Quest and the Irish government continue to settle the resulting lawsuits. On June 3, 2019, Quest announced that American Medical Collection Agency (AMCA), a billing collections service provider, had informed Quest Diagnostics that an unauthorized user had access to AMCA’s system containing personal information AMCA received from various entities, including from Quest. AMCA provides billing collections services to Optum360, which in turn is a Quest contractor. AMCA later went bankrupt after the breach. ==References== ==External links==
