While I consider the office/lab experience very pleasant, I can only tell you that I hope no one has a billing discrepancy with them. My husband had blood work last July 2024. After our dr office straightening it out in Oct 2024, and two different phone calls/-waiting on hold for over 25 minutes with Quest, I finally received our 651.71 refund on 06/29/2025!!!! Heaven help anyone with a billing question with Quest Diagnostics!!! They demanded our money almost a year ago which I paid. Only because they threatened to ding our good credit if we didn't pay within 30 days!!!! Then, it took them almost a year to send a refund!!!! Accessibility with them is a nightmare!!!! Good luck and hope your Doc uses the correct codes with Quest!!!! read more
