LabCorp is very quick to put a bad permanent (7 years) mark on your credit report if you can't pay a medical bill. They use a collections company called RADIUS GLOBAL SOLUTION. Watch out!
Tip for consumers: Beware if you don't have insurance. They will not give you opportunity to pay.
This company is exceedingly hard to get erroneous listing changed on. It took me many months to have personal data removed, and I was told by *******@reply-corp.com that it was Google's fault.
Tip for consumers: Be very careful about any information you provide. Once it's place there, there is zilch in customer service support.
