Quest Diagnostics offers an online bill payment portal where you can pay from your computer or phone using a bank account or debit card
Quest Diagnostics bills for lab work and diagnostic tests can be paid through their patient portal at patient.questdiagnostics.com. You'll need to create an account or log in with existing credentials, then navigate to your bill and select the payment option. The portal accepts electronic bank transfers (ACH) and debit cards, though credit cards are not accepted for online payments.
Payment typically processes within one to two business days when you use a bank account, and immediately when you use a debit card. If you're paying an overdue balance, the portal will show your current amount due and any late fees that have been added. You can also set up a one-time payment or arrange a payment plan through the same portal if your bill is large.

Creating and accessing your Quest Diagnostics patient account
To pay online, you first need a patient account. Visit patient.questdiagnostics.com and select "Register" if you don't have one. You'll provide your name, date of birth, email address, and create a password. Quest will ask you to verify your identity by answering security questions or confirming information from your test order.
Once your account is active, log in and select "Billing" or "My Bills" from the menu. The portal displays all bills associated with your account, including tests from different dates and locations. If you've had multiple tests billed separately, each will appear as its own line item with its own balance due.
What payment methods are accepted and how long they take
Quest Diagnostics accepts two payment methods through their online portal: electronic bank transfers (ACH) and debit cards. Bank transfers are free and take one to two business days to clear. Debit card payments process immediately but may carry a small convenience fee depending on your bank.
Credit cards cannot be used for online payments through the patient portal. If you want to pay by credit card, you would need to call Quest Diagnostics billing directly at the number on your bill and arrange a phone payment, though this may also incur a fee. Checks and money orders can be mailed to the address shown on your statement, but these take longer to process and post to your account.
Understanding what appears on your Quest Diagnostics bill
Your Quest bill shows the test or panel name, the charge amount before insurance, any insurance payment or adjustment, and your out-of-pocket balance. If your insurance has already paid part of the bill, the amount due will reflect only your responsibility. If insurance hasn't processed yet, you may see a note saying "pending insurance" or "awaiting insurance information."
Some bills include multiple tests ordered at the same visit, and each may be billed separately if they go to different insurance plans or if one is covered and another is not. Late fees appear on the bill if payment is more than 30 days overdue. The portal shows the date the bill was generated and the date payment is due, though many providers will work with you if you contact them before that date.
Setting up a payment plan if you cannot pay the full amount
If your bill is too large to pay in one payment, Quest Diagnostics allows you to request a payment plan through the patient portal or by calling their billing department. Payment plans typically break the balance into monthly installments over three to twelve months, depending on the total amount owed. There is usually no interest charged on payment plans, though some arrangements may require a down payment.
To request a plan online, select your bill and look for a "Payment Plan" or "Arrange Payment" option. If that option is not available, call the number on your bill and speak with a billing representative. They will ask about your income and ability to pay, then propose a schedule. Once you agree, you can make payments through the portal each month or set up automatic payments from your bank account.
What to do if you cannot find your bill or account online
If you've created an account but don't see a bill, the test may not have been billed yet. Lab work typically appears in your account within five to ten business days of the test date. If more than two weeks have passed, contact Quest Diagnostics directly using the phone number on any paperwork you received at the test location.
If you never received a bill by mail and cannot locate it online, call Quest Diagnostics billing to request a copy. Have your date of birth, the test date, and the location where you were tested ready. The representative can email or mail a bill to you and may also help you set up online access if you're having trouble with the portal.
Paying a bill if you don't have online access or prefer another method
Not everyone has internet access or prefers to pay online. Quest Diagnostics accepts payments by phone, mail, and in person at some locations. To pay by phone, call the number on your bill and provide your account number and payment information. Phone payments are processed the same day if you call before the payment deadline.
To pay by mail, write a check or money order and send it to the address shown on your bill. Include your account number on the check. Mail payments take seven to ten business days to arrive and process, so send them early if your due date is approaching. Some Quest locations also accept in-person payments at the front desk, though this is less common than phone or mail options.
Frequently Asked Questions
Can I pay my Quest Diagnostics bill with a credit card online?
No, the online patient portal only accepts bank account transfers and debit cards. If you want to pay by credit card, you can call the billing number on your bill and arrange a phone payment, though a convenience fee may apply.
How long does it take for my online payment to show up on my account?
Debit card payments process immediately. Bank account transfers (ACH) take one to two business days. Once the payment clears, it will show as posted on your account and your balance will update.
What happens if I miss the due date on my Quest Diagnostics bill?
Late fees are added to your balance after 30 days. You can still pay online or by phone after the due date. If your bill goes unpaid for several months, Quest may refer it to a collection agency, which can affect your credit report.
Can I set up automatic monthly payments for a payment plan?
Yes. Once you arrange a payment plan, you can usually set up automatic payments from your bank account through the patient portal. This ensures you don't miss a payment and helps you stay on schedule.
Do I need to create a separate account for each family member's tests?
Yes, each person needs their own patient account. You can manage multiple accounts by logging out and logging back in with different credentials, but you cannot view another person's bills or medical information in a single account.
