DNA tests are for informational purposes and are self-collected unless otherwise noted. Legal and immigration DNA tests require an in-person, ID-verified collection at an approved network location; instructions are included with your order confirmation. No physician review is required for these tests.
This test compares DNA between two or more people to answer relationship questions other than direct paternity — including siblingship, grandparentage, avuncular (aunt/uncle) testing, twin zygosity (whether twins are identical or fraternal), and missing-parent cases where a parent is not available to test directly.
Each participant collects their own cheek swab with an easy mail-in kit. This is an informational test, for personal knowledge — it is not collected under witnessed, ID-verified conditions, so it is not intended for court or immigration use. Let us know which specific relationship you are testing for so we can confirm the right combination of kits before you order.
