SIBLING DNA TESTING
Sibling Paternity Testing
Do you need to determine paternity but the alleged father is unavailable for testing? A sibling DNA test is a reliable option to find the answers you need. S-DNA offers professional service with easy appointment setup for informed decisions based on your circumstances.
What is a Sibling DNA Test?
A sibling DNA test analyzes Deoxyribonucleic Acid (DNA) Standard Tandem Repeat (STR) markers to determine the probability that two people share both biological parents or a common parent.
Testing Options:
- Home Sibling DNA Test Kit: This non-legal test is for informational purposes only.
- Legal DNA Sibling Test: This option provides results that can be used as evidence in legal cases to prove biological relationships.
All samples are tested by our accredited partner laboratory, AABB (formerly the American Association of Blood Banks). This ensures a proper chain of custody and unbiased sample collection. Your results will be recognized by family courts and state institutions nationwide. To learn more about the types of testing below.
Types of Sibling Tests:
We offer two types of sibling tests:
- Full Sibling DNA Test: Determines if two or more possible siblings share both biological parents.
- Half Sibling DNA Test: Determines if two alleged siblings share one common parent. This test is useful when the alleged father cannot participate in a paternity test.
Common Uses:
Here are some common reasons for conducting a sibling DNA test:
- Adding an alleged father’s name to a birth certificate
- Immigration cases for visa acquisition
- Social Security benefits for a deceased biological father
- Peace of mind
- Inheritance matters

Frequently Asked Questions About Sibling Tests
Is Sibling DNA Testing Accurate?
Our sibling DNA testing involves submitting samples to our partner laboratory for comprehensive analysis of 18 to 24 genetic markers. The lab provides strong statistical evidence for determining sibling relationships.
Results are expressed as likelihood ratios rather than absolute certainties. Including additional participants, particularly the mother, enhances the accuracy of the conclusions.
Should the Mother Be Included in a Sibling Paternity Test?
Yes, including the mother’s DNA sample is strongly recommended when available. For full siblings, her participation helps confirm shared maternal inheritance. For half-siblings, her DNA allows for better differentiation between shared and unique DNA, leading to more accurate analysis.
Are Home DNA Sibling Test Results Private?
All genetic samples and results remain confidential. We do not sell information to third parties. Specimens are retained for three months before destruction. Results are released only to participants involved in the test. An unrelated third party receives results only with a court order presented to the lab, which will notify clients before releasing results.
