Terms of Service

DirectDx Terms of Service (TOS)

We welcome you to DirectDx.net (“DDX” “we” “our” “us”). DDX provides its licensed member clinicians and the organization said clinician represents (“clinicians” “you” “your” “I”) with access to major and specialty laboratory services at lower costs.

DDX does not require a membership fee and there are no annual fees or minimum ordering requirements to participate. Accounts can be terminated at any time for any reason.

Signing Up

These Terms of Service and Privacy Agreement will govern our relationship and are a contract governed solely by Georgia law. Our service (Quest Diagnostics and Labcorp) is not available in NY, NJ, MA, or RI. Only clinicians who practice in and are licensed in MA may use DirectDx.net for Labcorp and Quest testing. Testing restrictions for other labs will be posted in the test’s descriptions.


You must maintain a valid credit card on file prior to ordering lab tests. You may incur a per patient phlebotomy charge at the draw site/facility, in addition to the costs of each test ordered (especially if they are drawing for a specialty lab test kit). The phlebotomy charge is added to your bill and not collected at the draw station (Labcorp and Quest Diagnostics) for tests they run (not kits from specialty labs). Your credit card will be charged when the test results and receipt are transmitted to you. Charges are itemized by the patient and will appear on your emailed receipt or fax cover sheet. Further, in the event that your credit card on file is declined, you agree and authorize DDX to attempt to charge your credit card until all unpaid transactions are satisfied. In the event your credit card is declined, DDX reserves the right to suspend your lab testing privileges or terminate your DDX account completely. In the case of bimonthly payments, you also agree to pay your bill in full on the 1st and 15th of each month or risk the balance being submitted to collections. Billing dates can change at any time and we will notify you of that change.

You must maintain current contact information, credit card information, and professional license information with DDX. You may send a Cancel Membership email to [email protected] to terminate your lab testing privileges with DDX, but in any event, the remainder of these Terms of Service will remain in effect until all outstanding invoices are paid.

DDX does not own or control any entity that interprets results or sells nutritional products or drugs. DDX does not offer interpretations of laboratory results. I understand that DDX does not accept insurance or file insurance claims and that I am ultimately responsible for all aspects of the care and well-being of my patients including the interpretation of their test results.

I agree to follow the Basic Ordering Instructions and complete all forms according to DDX guidelines for both paper and electronic requisitions, and if I do not, my membership may be suspended or terminated at the sole discretion of DDX. I assume all financial responsibility for the costs of testing ordered by me regardless of when testing occurs.
