One day following the announcement of the Quest Diagnostics breach, LabCorp produced a filing with the U.S. Securities and Exchange Commission that it too had been impacted by the hack of AMCA. An additional 7.7 million patients’ names, addresses, dates of birth, and balance information have been exposed.

What Happened?

On Monday, June 3rd, 2019, Quest Diagnostics, one of the largest clinical testing networks in the U.S., disclosed a data breach that impacted the personal information of approximately 11.9 million patients. The breach exposed credit card and bank account numbers, Social Security numbers, and medical information of Quest Diagnostics labs patients. The statement came after one of Quest Diagnostics’ vendors, American Medical Collection Agency (AMCA), notified the laboratory that an unauthorized third-party had accessed its systems and took control of its payments page between August 1st, 2018 and March 30th, 2019.

The investigation remains open, but it is not believed lab test results were included in the breach. Quest Diagnostics serves nearly half of all physicians and hospitals across the U.S. in  2,200 locations.

Should You Be Worried?

It is not yet known exactly which patients had their personal, financial, and medical information exposed. However, if you have taken a drug test or if you’ve had blood work, Quest Diagnostics may have been your lab provider. Keep a close eye on your mail and email and watch for a potential breach notification.

3 Tips to Stay Protected

  1. Monitor your financial accounts. Read your bank and credit card statements carefully for any suspicious activity, especially if you receive notification from Quest Diagnostics that your personal information was part of the breach.
  2. Freeze your credit. By freezing your credit at each of the three credit bureaus you’ll restrict access to your credit report, adding an extra layer of defense against identity thieves.
  3. Keep an eye out for medical identity theft. Watch out for these red flags that may indicate you are a victim of medical ID theft.
