Your kit number (sample number) is a unique multi-digit number that is associated with your DNA sample and test results. You do not need to create or register a kit number, it is automatically assigned when you order a test. It includes the contact information you entered when first ordering your test. Many aspects of your results and our datrabase are identified by your kit number, and it is crucial for the processing and reporting your results. For this reason it cannot be changed once assigned. Only one kit number will be assigned to you. Please keep this number in a safe place because you will need it to access your results.
