How We Bill

Prepayment is preferred on all samples submitted. In the event that prepayment is not made, payment for each case is due upon receipt of the monthly invoice. A monthly statement and invoice will be sent to client at the beginning of the month with an account balance covering all charges accrued the prior month. The monthly statement reflects all payments received as of the invoice date.

Submitting clinics are our clients. The submitting clinic is responsible for all fees incurred, to include collections fees, and all entities must adhere to the billing policy. Without prior approval from the business office and respective lab, other parties will not be held responsible for outstanding balances.

Balances not paid within the 30 day grace period from the date of the invoice are subject to a 1.5% interest charge assessed monthly. Accounts with a credit balance will be refunded within 4-6 weeks after making a refund request to the business office. Test results are released only on accounts in good standing.

Accounts with balances older than 60 days will be placed on hold and samples received will not be processed until payment is received to bring the account current. If a sample is deemed unsuitable after being held for payment, the responsibility for charges incurred with collecting and submitting another sample are the responsibility of the submitting clinic. Accounts with balances older than 90 days will be referred to a professional collections agency.

Fees are subject to change without notice. Current fee schedules are available on our website. Checks and money order payments must be issued in U.S. Dollars. Visa, Master Card, Discover, and American Express credit cards are also accepted. Please note specific sample information on each payment.

To pay by credit card please go to, select Accounting & Billing, and click the “Pay Now Online” button.

Payments via bank wire transfer, or EFT, are also accepted. Please email to obtain bank transfer information. Please note that our bank accepts these payments for free. However, processing banks can deduct fees before the payment reaches our bank. Only the amount received by our bank will be applied to your account. Any deducted fees or short-payment remain the responsibility of the submitting clinic.

Returned check / Declined credit card policy
If an owner submits a form of payment that is returned by our bank or declined by Merchant Services, the balance is the responsibility of the submitting clinic. In addition, if a check payment is returned by our bank, the submitting clinic will be billed a returned check fee of $30.

Set Up an Account

Accounts are set up based on the information received through the submitting paperwork. If clients have other particular information they’d like to use to set up an account (special billing addresses, P.O. Box numbers, or special delivery methods), you can contact Accounts & Billing before or after the samples are received.
