ACCU Reference Medical Laboratory Under Investigation for Data Breach of Patient Records

Schubert Jonckheer & Kolbe LLP is investigating a data breach that led to unauthorized access to patient information held by ACCU Reference Medical Laboratory, a New Jersey-based full-service medical laboratory.

Ransomware group Qilin reportedly posted unredacted patient health information on its Dark Web site on July 10, 2025. This cyberattack does not appear to be a re-listing of data from the December 2023 cyberattack on ACCU Reference. It appears that ACCU Reference failed to notify patients in 2023 and 2025 that their private information was stolen.

If your personal information was impacted by this incident, you may be at risk of identity theft and other serious violations of your privacy. As a result, you may be entitled to money damages and an injunction requiring changes to ACCU Reference’s cybersecurity practices.
