Medical laboratory operator Quest Diagnostics Inc. says a hack of an internet application on its network has exposed the personal health information of about 34,000 people, reports the Associated Press.

The Madison, New Jersey-based company says "an unauthorized third party" on Nov. 26 gained access to customer information including names, dates of birth, lab results and in some instances, telephone numbers.

The stolen data didn't include Social Security numbers, credit card accounts, insurance details or any other financial information.

Quest said Monday it's working with a cyber security firm and law enforcement to investigate the breach while taking steps to prevent similar incidents from recurring.

The company said it's notified affected clients by mail.
