Quest Diagnostics fax number for lab records

ProntoFax is an independent fax service. We are not affiliated with, endorsed by, or connected to Quest Diagnostics.

Quest Diagnostics billing fax number

Quest has no single fax number for billing. Its billing questions page says the mailing address and fax number for billing correspondence are printed on your bill, so the right number depends on the bill. That is why we do not list one here. Use the fax number on your own Quest bill, and write your bill number on anything you send.

For other medical offices, insurers and government agencies, our fax number lookup lists numbers read off each one’s own website, with the date we last checked.

Getting your records back

The form asks how Quest should send what you requested: by mail, by email or to a fax number. ProntoFax sends faxes and does not receive them, so choose mail or email for your copy. Quest says it responds within 30 days of receiving the form.

For results you can see right away, Quest points patients to its MyQuest website and app.

If your doctor’s office is the one asking you for a form, fax it to the office instead. Our page on faxing a doctor’s office covers that.

How we verify fax numbers

Every number on this page was published by the agency itself. The two columns beside it say when that number was last confirmed, and what confirmed it.

The Verified by column says which of these it was:

Official website the agency publishes this number. The date is the day we read it from their page or their published file.

✓ProntoFax user a fax sent through ProntoFax reached this number and the receiving machine confirmed it. The date is the most recent delivery.

ProntoFax automation we called the number and heard a fax tone answer. Nothing is sent and the call ends as soon as the line answers.

!Needs verification recent attempts to this number did not go through. It stays listed because the agency still publishes it, but check it against your own letter before you send.

The date is colored by how long ago it was:

Within 90 days 91 to 270 days Over 270 days

We never add a number because someone faxed it. A number appears here only if the agency published it. A delivered fax can confirm a number, but it can never create one.

What goes to this number

Quest’s access form says to fax these here:

• The completed patient access form, to get copies of your own lab results or your test order form
• The same form, to have Quest send your records to another person
• Proof that you can act for the patient, such as a court order, healthcare proxy or power of attorney, if you are a guardian or an authorized representative

What to include

Fill in every field the form marks as required. Those are:

• The patient’s full name, and any other name used at the time of the test
• Date of birth
• Current address, and the address at the time of the test if it was different
• Which records you want: lab test results, the order form, or something else
• The Identification section: whether you are the patient, a parent, a guardian or an authorized representative
• How Quest should send the records, then your signature and the date

The form also asks for the doctor who ordered the test and the approximate dates. Fill those in if you know them, because they help Quest find the right records.

Send the form and any proof of representation together, in one fax. Send copies, not originals, and keep your delivery confirmation.
