Having undergone Quest bloodwork in October 2022, I started receiving suspicious texts in late December 2022, after an initial legitimate text from Quest in November 2022, informing me of a charge to my account. Given their ability to automatically collect funds, these messages seem to be a scam, particularly as my dad received a similar message, and I have found similar complaints online, so I advise against making any payments.
Quest Diagnostics text scam: what to watch out for!
Summary — +18662543859
Expert Opinion
Never click links in unsolicited billing texts! Scammers are using the 866‑254‑3859 number to pose as Quest Diagnostics and claim you owe a bill through a fake Zotec Partners portal. Treat any unexpected message demanding payment as suspicious, especially if it asks for personal or financial details. Verify the claim by logging into your official Quest account or calling the verified customer service number on the company’s website—not the number in the text. Delete the message, block the sender, and report the incident to the FTC or your phone carrier. Staying cautious protects your personal info, blocks phishing, and keeps your finances safe.

Hello, i recieved a call from this number, but didnt get a chance to talk

My experiance was similar, just blocked the number, scammers are everywhere...
A message allegedly from Quest Diagnostics was sent, stating a debt and providing a link or an alternate number, 1-866-254-3859, to contact them.
It seems there was a misunderstanding regarding the receipt of a test, which was likely meant to be a text, and it's worth reviewing the other posts for clarity and insight.
I received a suspicious text from this number claiming I had an outstanding bill from Quest Diagnostics, complete with a link to pay, which I believe is a scam since legitimate bills are typically sent via mail.
This text is a scam, I gave them a false name and birthday out of curiosty, and they transfered me to another department, but when I gave the same info again, they hung up on me, a legit buisness wouldnt do that
