How Does Sibling DNA Testing Work?

Choose the sibling DNA test that best suits your needs. Options include our standard DNA test kit, DIY, or multiple locations kits.

Use our pain-free, FDA-approved cheek swabs for simple DNA collection. Alternatively, for more discretion, you can send in alternative samples like a toothbrush, hair, or earwax.

Send your DNA samples and the completed result notification form back to our lab using the prepaid FedEx envelope (Note: shipping is not included with the DIY Test kit).

Your results will be emailed directly to you within 2-3 business days after arriving at our lab. Your dedicated DNA Specialist will ensure secure delivery via email or mail, complete with clear and detailed explanations, and is available to answer any questions you may have.

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
