Here are the answers to the most frequently asked questions about this test.

Yes, your results are 100% confidential. No one will be able to access your account or your results unless you give them your confidential account login. You can change the password to your account at any time. Please remember to safeguard your login information and not share it with anyone.
Testing begins immediately the day that your samples arrive at the laboratory. In some special situations, additional testing may be required, which could increase the turnaround time by a few extra days. You can check the status of your test online 24/7 using your secure account login. Your test report is released immediately once testing is complete.
Drinking or eating will not change the results in any way. The reason that you are not supposed to drink or have anything in the mouth for an extended period prior to collection is to ensure that we have enough buccal cells to complete the test. If there are not enough cells to complete the test, then the results will not be released and a recollection will be required.
No. You can send the kits back to the laboratory using any shipping method of your choosing. Please be advised that if you do not use the included prepaid return mailer to ship your samples, it is your responsibility to ensure that your samples arrive at the laboratory. We will not be able to provide assistance for shipments that do not use our prepaid return mailer.
