BEFORE YOU GET IN TOUCH

A little preparation helps

Keep your Quest Diagnostics purchase or service record close by while choosing one of the contact options below. No confirmed general telephone is supplied in this record; continue through the documented company website or help page. The business decides which requests it can handle through each channel.

Identify the product or service connected to your enquiry.
Use a clinician or emergency service for medical care, not this contact directory.
Exclude treatment records and other sensitive details from public reviews.
