Every family's situation is different. You don't need to know exactly which test to order before contacting us.

We'll help you understand the appropriate testing option and collection process.
Book online or contact us and tell us what you need the results for. We'll help determine the appropriate testing option for your situation.
Come to our Houston location for your scheduled appointment. Collection may involve a cheek swab, blood draw, or another approved method depending on the test.
Your samples are processed by the appropriate laboratory and results are delivered according to the testing service selected.
Sometimes you simply need to know. What's My DNA offers professional DNA paternity testing for individuals and families seeking clear answers about biological relationships.
For individuals seeking answers for personal knowledge. This option is intended for private use and may differ from testing required for official legal purposes.
For situations requiring documented collection and chain-of-custody procedures — including court matters, child support, custody, and birth certificate cases.

You don't necessarily have to wait until after birth to begin getting answers. Non-invasive prenatal paternity testing options may be available during pregnancy, typically involving a blood sample from the mother and a DNA sample from the alleged father.
Because eligibility, timing, collection requirements, and laboratory procedures can vary, we encourage you to contact us directly so we can help determine the appropriate option for your situation.
When a parent cannot participate in testing — or when you need to establish another biological relationship — additional DNA testing options may be available.
Establish a biological relationship between a grandparent and grandchild when a parent is unavailable for testing.
Determine whether two individuals share one or both biological parents through sibling DNA analysis.
Avuncular testing can help establish biological relationships between a child and an aunt or uncle.
Not sure which relationship test you need? Contact us and we'll help identify the right testing approach for your family's situation.
