LabCorp's online payment system lets you pay your lab bill directly through their website or mobile app without calling or mailing a check.
You can pay through LabCorp's patient portal if you have an account, or you can make a one-time payment without logging in. The portal is called LabCorp OnDemand, and it shows your test results, billing history, and payment options in one place. One-time payments go through a separate system that asks for your bill number or date of service to locate your account.
Payment methods accepted online include debit cards, credit cards, and bank transfers (ACH). LabCorp does not charge a fee for online payments, though your bank or card issuer may charge their own fees depending on your account type. Payments typically post within one to two business days.

How to set up a LabCorp OnDemand account
Creating an account on LabCorp OnDemand takes about five minutes and requires your date of birth, email address, and a password you choose. Go to labcorp.com, click "Sign In" in the top right, then select "Create Account." You will be asked to verify your identity by entering information from a recent LabCorp test or bill.
Once your account is active, you can log in anytime to view past test results, upcoming appointments, and any outstanding balances. The portal also stores your insurance information and lets you update it if your coverage changes. If you forget your password, use the "Forgot Password" link on the sign-in page to reset it by email.
Paying a one-time bill without an account
If you do not want to create an account, you can still pay online by going to LabCorp's one-time payment page. You will need one of the following: your bill number (found on your paper bill or email), your date of service, or your account number. Enter this information and your date of birth to locate your bill.
The system will show your balance due and let you choose your payment method. You do not need to create a password or provide any information beyond what is necessary to find your account. After payment, you will receive a confirmation number by email that you can save for your records.
Payment methods and processing time
LabCorp accepts Visa, Mastercard, American Express, and Discover for credit and debit card payments. You can also pay by bank transfer (ACH) if you have your routing number and account number available. Bank transfers typically cost nothing and may be faster than card payments for posting to your account.
Payments submitted before 11:59 p.m. Eastern Time on a business day usually post within one to two business days. If you pay on a weekend or holiday, the payment will process on the next business day. Your payment status will show as "pending" for a few hours after you submit it, then change to "posted" once it reaches LabCorp's system.
What to do if you cannot pay in full
If your bill is larger than you can pay right now, contact LabCorp's billing department before your account goes to collections. You can reach them by phone at the number on your bill, or through the "Contact Us" section of the LabCorp website. Explain your situation and ask whether a payment plan is available.
LabCorp may offer to split your balance into monthly payments with no interest, depending on the amount owed and your circumstances. Some bills may also be reduced if you meet income requirements for financial hardship programs, though this varies by location and test type. Getting in touch early gives you more options than waiting until a debt collector contacts you.
Troubleshooting common payment problems
If your payment is declined, check that your card number, expiration date, and CVV are entered correctly. Some cards block medical payments as a fraud precaution, so contact your bank to confirm the transaction is allowed. If you are paying by bank transfer, verify that your routing number and account number match what your bank shows.
If you cannot find your bill number or account number, check your paper bill, email receipt from your test, or insurance explanation of benefits. You can also call LabCorp's billing department with your name and date of birth, and they will look up your account. If you paid online but do not see the payment reflected in your account after three business days, contact billing with your confirmation number to confirm receipt.
Frequently Asked Questions
Does LabCorp charge a fee to pay online?
No, LabCorp does not charge a fee for online payments. Your bank or credit card company may charge their own fees depending on your account type, but LabCorp's system itself is free to use.
Can I set up automatic monthly payments for recurring bills?
LabCorp OnDemand does not currently offer automatic recurring payments through the portal. You can set up a one-time payment each month, or contact billing to discuss a payment plan if you have multiple bills.
What happens if I pay with a credit card instead of a debit card?
Both are accepted and processed the same way. Credit card payments may take slightly longer to post because the transaction goes through your card issuer first. Either method is safe and will show up in your account within one to two business days.
Can I get a receipt for my online payment?
Yes. You will receive a confirmation number and receipt by email immediately after payment. You can also log into LabCorp OnDemand anytime to view your payment history and print past receipts.
What if I paid online but my bill still shows as due?
Payments usually show as "pending" for a few hours after submission, then move to "posted." If more than three business days have passed and your account still shows the old balance, contact LabCorp billing with your confirmation number to verify the payment was received.
