Accurate, Private DNA Testing From A Trusted USA Laboratory
Choosing a DNA test is an important decision—one that deserves accurate analysis, professional laboratory standards, and complete privacy.
Many low-cost DNA tests sold through large online marketplaces are offered by unknown or overseas providers and may analyze a limited number of genetic markers. In relationship DNA testing, analyzing too few markers can reduce result confidence—especially in more complex cases.
PaternityUSA is dedicated to providing high-quality relationship DNA testing with clear, reliable results at fair and transparent prices. We offer two testing options so you can choose the level of analysis that best fits your situation:
- 24 marker testing: This is the test option used when performing a paternity test which is considered a relationship of the first order.
- 24–34 marker testing: This option is appropriate for many relationship questions particularly when the mom is also available for testing well.
- 46-marker premium testing: This is the recommended option for complex or indirect relationships such as sibling, grandparent, or aunt or uncle, where additional genetic data improves statistical confidence.
Our relational DNA tests are also a practical way to confirm or clarify genealogy-based findings from services such as Ancestry, 23andMe, or MyHeritage. Unlike genealogy databases, relational DNA testing directly compares individuals to evaluate whether a specific biological relationship is supported by genetic evidence.
If you believe you may have found a biological sibling, grandparent, or aunt or uncle, we can help you confirm your relationship with a professional, privacy-first testing process.
For more than 25 years, families have chosen PaternityUSA for dependable DNA testing that analyzes more than twice the number of genetic markers used in many standard 16–22 marker tests—up to 46 markers. All DNA testing is performed in the United States.

Maternity and paternity DNA testing is the most reliable way to evaluate a biological relationship between a father or mother and a child. When an alleged parent is unavailable or unwilling to participate, other relationship tests—such as sibling, grandparent, or avuncular (aunt/uncle) testing—may provide useful statistical evidence depending on the participants and case complexity.
