How to Order Tests

Clinical Diagnostic Samples?

All tests for clinical diagnostic purposes need to be ordered by a licensed healthcare provider or a genetic counselor. Specimen requirement and shipping instructions are provided in the Test Requisition Form.

Our tests are available in the U.S. and in some international locations. Please contact us for more information on test availability in your area.

Currently, we bill a referring provider’s institution directly for all clinical testing. We do not provide direct-to-payer or direct-to-patient billing services. Please click here to find out more. Please call (414)-316-3097 or email us if you have any questions.

New Customer?

If this is the first time you are sending a sample for testing at RPRD, we appreciate your trust and we are committed to doing our best to make sure all your inquiries are answered prior to the reporting test results.

To speed up the ordering process, please fill out our Customer Onboarding Form. The form will inform us about your point of contact, invoicing instructions, and payment process so that we can complete your order according to your preference. After you have filled your form, please email the form to us. An RPRD representative will contact you to set up a HIPPA-compliant results transfer process to transmit patient test results and the clinical reports.
