If you’re unsure which test best suits your needs, our friendly team is here to provide a free consultation. Contact Genetic Insights today to take the first step.

DNA Relationship Testing Options

Our relationship testing solutions are ideal even when a direct parent is unavailable. We offer both legally admissible and non-legal options depending on your purpose. Our tests provide trusted and accurate results, whether for personal knowledge, medical history, or legal proceedings.

These are the options:

> Maternity DNA Test

This test confirms whether a woman is the biological mother of a child. It works similarly to a paternity test, comparing the child’s DNA to that of the mother. The process is fast, simple, and reliable. Ideal for personal assurance, legal situations, or immigration purposes. Trust Genetic Insights for accurate maternity verification.

> Grandparent DNA Test

A grandparent DNA test determines if a child is biologically related to one or both grandparents. This option is useful when the biological parents are unavailable, whether due to legal matters, adoption, or loss. The test supports legal cases, medical history documentation, or personal clarity. Genetic Insights ensures accuracy and confidentiality throughout the process. Reach out today for a free consultation with our knowledgeable team.

> Sibling DNA Test

This test helps determine whether individuals are full siblings, half-siblings, or unrelated. By comparing genetic markers, the test provides a high-confidence analysis of the biological relationship. It’s commonly used when one or both parents are unavailable or when inheritance and legal issues arise. Results are delivered with precision, offering clear percentages of relation probability. Contact Genetic Insights to verify your sibling relationship today.

Key Points About Sibling DNA Testing

1. How It Works

• Sample Collection: Uses non-invasive cheek swabs (buccal swabs) from both individuals.
• DNA Comparison: Genetic markers are analyzed to evaluate shared DNA.
• Results: Results include probability percentages for full, half, or non-sibling relationships.

2. Types of Sibling Relationships

• Full Siblings: Share both biological parents.
• Half-Siblings: Share one biological parent.

3. Accuracy of the Test

• Full Siblings: Typically 99.99% or higher accuracy.
• Half-Siblings: Around 50%-70% accuracy.
• Non-Siblings: Little to no genetic match.

4. When Is a Sibling DNA Test Used?

• To confirm biological relationships when parents are unavailable.
• Inheritance or estate claims.
• Immigration purposes.
• Legal or custody cases.

> Twin DNA Test

A twin DNA test determines whether two individuals are identical (monozygotic) or fraternal (dizygotic). This test is often used for medical awareness, personal curiosity, or legal documentation. Genetic Insights compares genetic markers for complete zygosity confirmation. We offer both legal and at-home testing options to meet your needs. 

Why Consider Twin DNA Testing?

• Curiosity: Understand shared traits and differences.
• Medical Needs: Identical twins share identical genes—key for health decisions.
• Lost Records: Determine twin status if documentation is unavailable.

Twin DNA Testing Options

Genetic Insights offers two distinct types of twin DNA testing to meet your specific needs:

• Legal Twin DNA Tests

Legal twin zygosity tests are designed to meet court requirements and follow strict chain-of-custody procedures. All DNA samples must be collected at an approved facility—such as a hospital, health clinic, or certified testing center—and the identities of all individuals tested must be confirmed using valid government-issued identification or official documentation. These safeguards ensure the results are fully admissible in legal settings.

• At-Home Twin DNA Tests

At-home twin DNA tests provide the same high level of lab accuracy as legal tests but are intended for informational use only. While the collection process is simple and convenient, identity verification is not required, and chain-of-custody protocols are not followed. As a result, these results cannot be used in legal proceedings but are ideal for individuals curious about their twin status or genetic relationship.

Trusted Twin DNA Testing

Genetic Insights delivers accurate twin DNA testing through a U.S.-based lab accredited by AABB, CAP, and CLIA. Results are available within two business days after sample receipt and are reviewed by our in-house PhD team. From start to finish, we provide clear communication and expert support.

Advanced Ancestry Testing

Our GPS Origins® Ancestry Test uses a unique algorithm to trace your DNA to specific regions—even towns or villages. It offers deeper, more precise insights, whether you’re exploring your ancestry for the first time or building on previous tests.

> DNA Reconstruction Test

When a direct parent or close relative is unavailable for testing, DNA family reconstruction can help provide the answers you’re looking for. This type of testing examines and compares an individual’s DNA with that of extended family members, such as grandparents, aunts, or uncles, to determine the likelihood of a biological relationship. It’s particularly useful in complex family situations, including adoption, loss, or uncertain parentage. DNA family reconstruction can uncover missing links and help bring clarity to family structures by piecing together information from multiple relatives. Test results are typically available within five business days of sample receipt, and our experienced specialists are here to assist you every step of the way with free consultations and expert guidance.

> Aunt/Uncle (Avuncular) DNA Testing

Avuncular DNA testing is used to determine whether a child is biologically related to their aunt or uncle—typically the sibling of the child’s mother or father. This test is especially helpful in cases where the biological parent is unavailable or unwilling to participate. Analyzing shared genetic markers helps confirm extended family connections, making it useful for both personal and legal matters. The term “avuncular” refers specifically to the relationship between a niece or nephew and their aunt or uncle. Genetic Insights offers accurate, confidential testing for these scenarios, backed by expert review and lab precision.

> Infidelity DNA Test

When trust is broken or doubts arise, having answers can bring clarity and peace of mind. DNA testing for infidelity provides a reliable, science-based way to determine whether someone has been unfaithful. By analyzing fabric items such as underwear, bedding, or clothing, our expert forensic team at Genetic Insights can detect even trace amounts of male or female DNA. Every test is handled with the utmost discretion, giving you accurate, confidential results to help you make informed decisions about your relationship. 

Please note that due to state regulations, this service is not available in Alaska, Arizona, Florida, Georgia, Massachusetts, Michigan, Nebraska, New Mexico, New York, South Carolina, South Dakota, and Vermont.

All Website descriptions are in straight guidelines with DNA  diagnostic center (DDC).

We offer two private testing options, and every consultation is free and confidential:

• Detection & Comparison Test

This test identifies the presence of DNA on the submitted fabric, determines the gender(s) of any detected DNA, and compares it to your own to see if there is a match. It is ideal for situations where you want to verify whether additional DNA is present and whether it could belong to you or someone else. Results are 100% confidential, and your personal data is never shared or sold.

• Full Detection & Comparison Test

This option includes everything in the basic test—detecting DNA on the item, identifying gender(s), and comparing it to your own. Additionally, it provides a conclusive analysis of the presence of semen. This test is ideal when you need a comprehensive review of potential infidelity. Like all our services, your results remain private, and your genetic information is securely protected.
