Check My Rights →CareNexa, LLC, dba Molecular Testing Labs (“MTL”) was the subject of a data breach notification filed with the CA Attorney General. The AG filing was recorded on December 10, 2025. The breach or discovery date reported in the filing is March 7, 2025.
CareNexa, LLC, operating under the name Molecular Testing Labs (MTL), functions as a specialized clinical diagnostic and biomarker testing laboratory that processes complex molecular, genetic, and diagnostic assays. Because of its core operations, MTL routinely collects, analyzes, and stores an extensive volume of highly sensitive health and personal identifying information. Healthcare providers and direct consumers rely on MTL for advanced diagnostic testing, which requires the transmission and retention of comprehensive medical histories, biological sample data, and precise health metrics. Consequently, the organization maintains vast digital repositories containing some of the most private information an individual can possess, making its data infrastructure a critical focal point for regulatory compliance and cybersecurity. In 2025, CareNexa, LLC, dba Molecular Testing Labs (“MTL”) formally reported a significant data security incident to the California Attorney General, alerting regulators and the public that unauthorized actors had compromised its network environment. While investigations into such healthcare and diagnostic laboratory breaches typically uncover sophisticated cyberattacks—such as unauthorized access to legacy databases, targeted malware deployments, or the infiltration of third-party vendor conduits—the core issue centers on a failure to maintain robust perimeter defenses. In the healthcare testing sector, threat actors aggressively target systems precisely because clinical laboratories hold centralized pools of valuable patient and provider data that can be weaponized or monetized on the dark web. The data compromised in the MTL security incident encompasses a dangerous mix of personal identifiers and protected health information, creating severe, multi-faceted risks for affected individuals. Exposed categories typically include full names, dates of birth, Social Security numbers, medical record numbers, specific diagnosis and treatment information, and health insurance identification details. When medical diagnostic data is paired with foundational identifiers like Social Security numbers, victims face a heightened and long-term risk of targeted medical identity theft, fraudulent insurance claims, unauthorized prescription acquisition, and financial fraud. Unlike a stolen credit card, compromised genetic and diagnostic profiles cannot be canceled or replaced, leaving victims vulnerable to exploitation for years to come. As a custodian of electronic protected health information, CareNexa, LLC, dba Molecular Testing Labs (“MTL”) was bound by strict legal mandates under the Health Insurance Portability and Accountability Act (HIPAA), the California Confidentiality of Medical Information Act (CMIA), and state consumer protection statutes. These laws require covered entities and business associates to implement rigorous administrative, physical, and technical safeguards, including comprehensive data encryption, multi-factor authentication, regular vulnerability assessments, and continuous network monitoring. The occurrence of a data breach of this magnitude strongly suggests that MTL failed to adhere to these foundational regulatory standards, allowing unauthorized intruders to bypass security controls that should have been impenetrable. Receiving a formal data breach notification letter from CareNexa, LLC, dba Molecular Testing Labs (“MTL”) serves as legal confirmation that your confidential records were exposed due to corporate negligence, establishing the necessary legal standing to participate in a class action lawsuit. Under modern privacy litigation standards, affected individuals do not need to prove that they have already suffered actual financial loss or identity theft to seek legal recourse; the mere compromise of private data resulting from inadequate security is actionable. Our law firm is actively investigating potential class action claims against MTL on a contingency fee basis, meaning there are never any out-of-pocket costs or attorney fees unless we successfully recover compensation on your behalf.
Based on the data types reported in this filing, affected individuals face the following specific risks:
Your SSN is the master key to your identity. Once exposed, criminals can open new lines of credit, take out loans, or file taxes in your name.
Combined with a name and other leaked data, date of birth helps criminals pass identity verification questions at banks and government agencies.
Under the California Consumer Privacy Act (CCPA), you may have a legal claim against CareNexa, LLC, dba Molecular Testing Labs (“MTL”) if any of the following apply:
Applicable law: This breach was reported under the California Consumer Privacy Act (CCPA), which establishes your right to seek damages from CareNexa, LLC, dba Molecular Testing Labs (“MTL”).
The hours spent responding to a data breach — canceling accounts, contacting credit bureaus, updating passwords, and investigating fraud — represent compensable economic harm in data breach litigation.
Once your SSN is exposed, protection becomes an ongoing expense. Plaintiffs in data breach settlements have recovered costs for credit freezes, identity protection subscriptions, and time spent dealing with fraudulent accounts — sometimes covering multiple years of exposure.
HIPAA violations carry civil penalties between $100 and $50,000 per violation. Where a healthcare organization's negligence led to the exposure of protected health information, class members may recover statutory damages in addition to actual losses.
Several state data breach laws provide for statutory minimum damages — fixed amounts recoverable per affected individual regardless of actual loss. These provisions exist specifically to make legal action viable for victims who have not yet experienced direct harm.
Note: an attorney general breach filing does not by itself establish a settlement fund, a payment amount, or a claim deadline. If an official settlement notice is later issued, rely on that notice for payment details and deadlines.
No. Under California Consumer Privacy Act (CCPA) and federal law, the unauthorized exposure of your personal data — regardless of whether it has been actively misused — can be sufficient grounds for a claim. The breach itself is the injury.
Nothing. The Law Office of David S. Harris handles data breach cases on contingency — you pay zero upfront and owe nothing unless compensation is recovered.
Immediately place a free credit freeze at all three bureaus (Equifax, Experian, TransUnion). A freeze blocks new accounts from being opened in your name. Then file a complaint with the FTC at IdentityTheft.gov and contact our office — SSN exposure is one of the most serious breach types.
If CareNexa, LLC, dba Molecular Testing Labs (“MTL”) is a covered healthcare entity or business associate under HIPAA, affected patients have additional rights — including the right to an HHS complaint. These HIPAA violations also strengthen civil damages claims. Consult an attorney to understand your full remedies.
Statutes of limitations for data breach claims vary by state but typically run 2–4 years. Depending on when you learned of the breach, you may still have time. Contact our office for a free eligibility review — there is no cost to find out.
Accepting free credit monitoring from CareNexa, LLC, dba Molecular Testing Labs (“MTL”) does not waive your right to pursue legal action unless you signed a specific release waiving claims. In most cases, victims who accepted monitoring can still file.
Not necessarily. Many data breach victims are never notified directly. If your personal information was held by CareNexa, LLC, dba Molecular Testing Labs (“MTL”) during the relevant period, you may still qualify even without receiving a letter. A free eligibility review can confirm your status.
