Quick answer: The only fax number Quest Diagnostics publishes for patients is 1-855-854-9151. It receives the Patient Access Form, Quest's written request for copies of your lab results and records. Billing paperwork goes to the fax number printed on your bill. There is no public fax line for lab orders: your provider sends the order to Quest, or you bring a copy to your appointment.
Searching for a Quest Diagnostics fax number usually ends on Quest's location pages, which list a phone number and hours for each Patient Service Center but no fax. The one fax line Quest prints on its website is for records requests, on its Patient Access Form.
No fax machine at home? Sign the form on your phone and send it with mFax: type the number, attach the form and fax it free for 7 days. Once Quest's machine confirms every page, you can download a PDF receipt. Ordering offices are steered elsewhere: Quest points them to its online portal and EHR connections, covered below.

Check the number on the form before you fax
Fax numbers change, so confirm 1-855-854-9151 in section F of the current form before you send anything with your health details on it. "Quest" fax numbers on directory sites and other clinics' contact sheets often belong to one lab, department or client account, not to the records team. Our guide to looking up a fax number shows how to check one.
How Do I Get My Medical Records From Quest Diagnostics?
Start with MyQuest. If your results are in your MyQuest account, you can read them there without asking anyone; Quest's own form points you to MyQuest first for "fast and easy electronic access". When the results aren't there, Quest asks for a written request on its Patient Access Form.
Quest's form says it will respond within 30 days of receiving the request. Asking is your right, not a favor. A 2014 federal rule gives patients the right to get test reports directly from labs covered by HIPAA, and to have copies sent to a person they choose (Federal Register, February 6, 2014).
The form lists three ways to send it:
- Fax: 1-855-854-9151
- Mail: Quest Diagnostics, 9601 Renner Blvd, Lenexa, Kansas 66219, ATTN: Clinical Client Services
- Email:
KCNOCRequesttoAccess@questdiagnostics.com, which Quest itself marks "not recommended if unencrypted"
Fax is quicker than mail, keeps your details out of an unencrypted inbox, and leaves you with proof that the form arrived. For records held by doctors and hospitals rather than a lab, see our guide to faxing medical records.
How to Fax the Quest Patient Access Form
The form is two pages. Fill it in, sign it, and fax both pages, plus any proof of authority, in one transmission.
Download the form
Get the Patient Access Form from Quest's website; a Spanish version is there too. You can fill it in on screen or on paper.
Fill in sections A to D
Every field with an asterisk is required. That covers who you are, what you want copies of, and where Quest should send them; the table below goes section by section. Type into the PDF in our free PDF editor, which works entirely in your browser, or print it and write by hand.
Start the fax in mFax
Open mFax, choose New Fax and enter +1 855 854 9151. Attach the form and any proof pages. A paper copy can go in through the camera scanner in the iPhone, iPad and Android apps.
Sign section E and send
Open the form's second page, choose Edit page, then Sign to draw your signature with a finger, mouse or trackpad, and date it with Text. Add a cover sheet with Confidential ticked, check the page count and press Send.
Keep the receipt
The fax shows Delivered once Quest's machine confirms every page. Choose Download receipt to keep a PDF record that it went through. Quest counts its 30 days from receipt of the form, so hold on to the receipt until the copies arrive.

What the Access Form Asks For
The form asks for some details as they were when the test was done, so write those exactly as they were then.
| Section | What to fill in | Tip |
|---|---|---|
| A. Patient's information | Name, name at the time of service or other spellings, date of birth, current address, address at the time of service (all required); phone, last four digits of your SSN, insurance ID (optional) | If your name or address has changed since the test, fill in both versions |
| B. Test order information | Ordering physician or office, address, phone, approximate dates of service; the records you want (required) | Tick Laboratory Test Results for copies of results |
| C. Identification | Whether you are the patient, a parent, a legal guardian or an authorized representative (required) | Guardians and representatives add proof, such as a court order, healthcare proxy or power of attorney |
| D. Delivery instructions | Your address, another address, a fax number, email, or other people who should get copies (required) | See the next section |
| E. Signature | Signature and date (required) | Sign after the rest is filled in |
| F. Where to send it | Mail, fax 1-855-854-9151, or email | Fax or mail keeps the form out of an unencrypted inbox |
How Quest Sends the Records Back
Section D decides how the copies reach you. You can choose your current address, another address, a fax number or email. You can also name other people who should get a copy, with their address, fax number or email.
For email, Quest's standard practice is encrypted email, which asks you to create a free account or log in to open the message. That account is separate from MyQuest. Unencrypted email is offered only if you accept the risk the form describes.
To get the copies by fax, write your own fax number. Every mFax plan includes a US or Canadian number for receiving, picked in Settings › Fax number. Incoming faxes are saved as PDFs in the app, stored encrypted on US servers, and announced with a push notification on iPhone, iPad and Android. Quest can take up to 30 days to answer, so give a number you will still have by then.
Can You Fax Lab Orders to Quest?
Not to any number Quest publishes. Quest's instructions for patients describe two routes for a lab order (Quest: prepare for your visit):
- Your provider or employer sends it directly to Quest. In Quest's words, "we already have it and you do not need to bring a copy".
- You bring a copy of the order to your visit, along with a photo ID and your insurance card.
Quest's location search lists each Patient Service Center's phone number and hours, but no fax line. To get an order to one location ahead of time, call that location and ask how it takes orders before anything with your health details goes out.
How Do I Send My Lab Order to Quest?
In most cases you don't send it at all. Pick the line that matches your order:
- Your provider ordered electronically: nothing to send. To confirm that a standing order is on file and ready, Quest asks you to call 1-866-MYQUEST (1-866-697-8378).
- You have a paper or PDF order: bring a copy to the appointment, along with your ID and insurance card.
- You booked an employer drug or alcohol test: follow your employer's instructions, or call Quest Diagnostics Employer Solutions at 1-800-877-7484.
If You Are the Ordering Office
Quest points healthcare professionals to Quanum Lab Services Manager, its online portal for ordering tests, viewing results, ordering supplies, tracking orders and scheduling specimen pickups. Quest's contact directory sends "request a copy of test results", "add or cancel tests from an existing order" and "track a specimen" to the same portal.
Fax lines printed on other hospitals' and clinics' Quest contact sheets belong to those organizations' accounts. Use the contacts that came with your own Quest account rather than borrowing one.
How Do I Send Quest Results to Another Doctor?
If the result is in MyQuest, send it from there. MyQuest's help pages describe print, email and fax options on each result, plus a Direct message for doctors you have connected; Quest warns that the email is unencrypted.
If the result isn't in MyQuest, use the Patient Access Form. In section D, tick Person(s) named below and write the doctor's name and fax number, then fax the form to 1-855-854-9151. That is the federal right to direct a copy to someone you choose, in Quest's own paperwork.
Holding a paper copy that Quest mailed you? Snap it with the camera scanner in the mFax app for iPhone, iPad or Android. Edge detection and auto-crop turn it into a fax-ready PDF that you can send straight to the doctor's office.
How Do I Fax Quest About a Bill?
Use the fax number printed on your bill. Quest doesn't list a billing fax on its website; its billing FAQ sends you to the bill instead (Quest: billing and insurance). Quest names two cases where you send paperwork:
- The bill asks for more information. Send it "to the address or fax number listed on your bill", or call the customer service number printed there. If the message says your insurer needs the information, Quest asks you to contact the insurer instead.
- Your insurer's Explanation of Benefits (EOB) doesn't match your Quest bill. Write your bill number on the EOB and mail or fax a copy, using the correspondence address and fax number on the bill. Quest then contacts your insurance company to sort out the difference (Quest: understanding the cost of your care).
A paper EOB is easy to send from your phone: scan it with the mFax camera scanner, add your bill number with the Text tool under Edit page, and fax it to the number on your bill.
Is There a Way to Contact Quest Diagnostics?
Yes, by phone and online, but Quest lists no general fax line. These are the contacts Quest gives on its customer service page and contact directory:
| Who | Contact | Use it for |
|---|---|---|
| Quest customer service | 1-866-MYQUEST (1-866-697-8378) | Patient questions, billing questions, standing orders |
| Quest billing | Online contact form, or the phone and fax numbers on your bill | Questions about a bill, EOB mismatches |
| Quest Experience Support | 908-900-4475 | Privacy, confidentiality or clinical concerns |
| Quest Diagnostics Employer Solutions | 1-800-877-7484 | Employer drug and alcohol testing |
| Ordering offices | Quanum Lab Services Manager | Results, test changes, supplies, specimen pickups |
Quest warns that its web forms are not a secure way to communicate and asks you not to put personal health information in them. For anything that carries your health details, use the access form by fax or mail.
Before You Fax Health Information to Quest
A records request carries your name, date of birth and details of your tests, so a few habits are worth the extra minute:
- Confirm the number in section F of the form you are sending, not from a directory site.
- Send everything in one fax. mFax combines several files into one fax, up to 60 pages, so the form and any proof of authority arrive together.
- Mark the cover sheet Confidential and keep test details off it, since the cover page is the first sheet anyone at the receiving machine sees. Our guide to a fax cover sheet for medical records shows what goes on it.
- Keep the receipt until the copies arrive. If you have to follow up, it shows the form went through.
For Practices: A Fax Line With a Signed BAA
Your Quest orders may run through Quanum, but records requests, referrals and results from other labs often still arrive by fax. mFax Business gives your practice its own fax number with HIPAA-compliant faxing and a signed BAA, on web, mobile and desktop. Plans start from about $9/mo, and you build your own plan from the seats and pages you need. Our guide to HIPAA-compliant fax explains what the BAA covers.
