Paying your Quest Diagnostics bill through their website
Quest Diagnostics operates a bill payment system at questdiagnostics.com where you can pay lab charges online using a debit card, credit card, or bank account. The payment goes directly to Quest, not through a third party, and the site accepts most major cards plus ACH transfers from checking or savings accounts.
You will need your bill or account number to start. If you do not have it, you can look up your account using your date of birth and the phone number or email address associated with your Quest account. The payment processes immediately for card payments; ACH transfers typically post within one to three business days.
Quest does not charge a fee for paying online through their own website. If you use a third-party bill payment service or your bank's bill pay feature to send a check on your behalf, those services may charge their own fees, but Quest's direct payment portal is free.

What information you need before you start
Gather your Quest account number or the bill number from your statement before you go to the payment page. The account number appears on any bill or explanation of benefits (EOB) you received from Quest. If you threw away the paper bill, you can retrieve your account number by logging into your Quest patient portal or calling Quest customer service at 1-866-697-8378.
You will also need the payment method itself — the card number and expiration date if paying by card, or your bank's routing number and account number if paying by ACH transfer. Have your billing address handy as well, since the payment form will ask you to confirm it.
Step-by-step process for online payment
Go to questdiagnostics.com and look for the "Bill Pay" or "Pay My Bill" link, usually found in the top navigation or under an account section. Click it and you will be taken to a payment portal.
Enter your account or bill number in the first field. The system will pull up your account and show you the balance owed. Review the amount to make sure it matches your bill. If you have multiple bills or accounts, you may see a list; select the one you want to pay.
Choose your payment method: credit card, debit card, or bank account. If you choose a card, enter the card number, expiration date, and the three-digit security code on the back. If you choose ACH, enter your bank's routing number, your account number, and whether it is a checking or savings account.
Enter the amount you want to pay. You can pay the full balance or a partial payment. Confirm your billing address and review the summary. Click to submit the payment. You will receive a confirmation number on screen and usually via email within a few minutes.
What happens if you cannot pay the full amount
Quest allows partial payments through their online system. You can pay whatever amount you are able to afford, and the remaining balance will stay on your account. There is no penalty for paying in installments through the website.
If you owe a large amount and want to set up a formal payment plan, you can contact Quest's billing department at 1-866-697-8378 to discuss options. Some locations or situations may allow you to spread payments over several months, though this is handled separately from the online payment system and may require a phone call to arrange.
If your bill has already gone to collections
If your Quest bill was sent to a collection agency, paying through questdiagnostics.com may not stop collection activity. Collection agencies buy the debt and handle it separately from Quest's billing system. Paying Quest directly after a collection agency has the account may not satisfy the collector.
Before you pay, contact the collection agency listed on your bill or credit report and ask whether paying Quest will resolve the debt or whether you need to pay the collector instead. Some collection agencies will accept payment from the original creditor; others will not. Get this in writing if possible before you send money.
Payment security and what to watch for
Quest Diagnostics uses encryption to protect card and bank information during online payments. The payment page should show a padlock icon in your browser's address bar, indicating a secure connection. Never enter payment information on a page that does not show this lock.
Be cautious of emails or text messages claiming to be from Quest and asking you to click a link to pay your bill. Scammers often impersonate medical providers. If you receive an unexpected message, go directly to questdiagnostics.com by typing the address yourself rather than clicking a link in an email. Quest will not ask for your full card number or bank account number via email or text.
Other ways to pay if online does not work for you
If you cannot or do not want to pay online, Quest accepts payments by phone at 1-866-697-8378. A representative can take your card or bank information over the phone and process the payment immediately. This method is also free.
You can also mail a check to the address shown on your bill. Include your account number on the check and mail it to the address listed under "Make checks payable to" on your statement. Mailed checks typically take five to ten business days to post, depending on mail delivery and Quest's processing time.
Some health insurance companies allow you to pay patient responsibility amounts through their own bill pay portals if the charge is tied to your insurance claim. Check your insurance company's website to see if this option is available for your Quest charges.
Frequently Asked Questions
Can I pay a Quest bill without creating an account?
Yes. You can pay as a guest using your account or bill number without logging in or creating a patient portal account. The payment page will ask for your account number and billing information, but you do not need to set up credentials first.
What if I do not know my account number?
Call Quest customer service at 1-866-697-8378 with your date of birth and the phone number or email on file. They can look up your account number and tell you the balance owed. You can then use that number to pay online or over the phone.
Will paying my Quest bill online affect my credit score?
Paying your bill will not hurt your credit. However, if the bill was unpaid for a long time and was reported to credit bureaus or sent to a collection agency before you paid, that negative mark may already be on your report. Paying now stops future damage but does not erase past late payments.
How long does it take for my payment to show up?
Card payments show as processed immediately and appear in Quest's system within hours. ACH bank transfers take one to three business days to clear. You will receive a confirmation number right away either way, which you can use to track the payment if there are questions later.
Can I set up automatic recurring payments?
The standard Quest payment portal does not offer automatic recurring payments. You must log in and make each payment manually. If you want to set up automatic payments, call 1-866-697-8378 to ask whether your specific account or location offers this option.
