Who Benefits from Sibling DNA Testing?

Are you looking to confirm if your children share the same biological father but prefer not to conduct a paternity test? A Sibling DNA Test can provide the answers you need.

If you've taken an ancestry DNA test and want to confirm the results, a Sibling DNA Test is a reliable next step to determine if you are truly biological siblings.

In situations where you're reconnecting with potential family members after adoption, a Sibling DNA Test can help verify those biological connections, offering clarity and support in your journey.

If parent testing isn't possible, a Sibling DNA Test can confirm biological relationships, offering court-admissible results for legal needs or personal clarity. Schedule your in-office DNA testing
