Family Relationship DNA Testing Services

We help families get clear answers through a full menu of biological relationship verification services. Our certified collectors use a simple buccal cheek swab for most tests, so your visit is quick and non-invasive while still providing highly reliable results.

You can choose Court-Admissible or non-legal options depending on whether you need results for personal knowledge or for use in legal proceedings. We explain each choice in plain language so you can select the right path for your situation.

• Paternity: Paternity testing compares DNA sequences from a potential father and child using a painless buccal swab sample collection.
• Maternity: Maternity testing confirms whether an individual is the biological mother of a child, helpful in adoption and hospital record questions.
• Sibling relationship testing: Sibling tests help determine whether two or more individuals share one or both biological parents.
• Grandparent and extended family testing: Grandparent, aunt, uncle, and other extended family tests assess biological connections when parents are unavailable or unwilling to test.
• Adoption Testing: Adoption Testing supports adoptees and birth families who want to understand biological background and confirm family links.
• Twin Zygosity: Twin Zygosity testing identifies whether twins are identical or fraternal for personal, medical, or donor-eligibility purposes.

In Maryland, paternity for unmarried parents may be established through an affidavit of parentage, marital presumption, or a court order. DNA testing can provide the biological evidence that supports the court-order pathway within Maryland family law paternity establishment.

Court-Admissible & Legal DNA Testing

When results need to stand up in court or before a government agency, collection and documentation matter just as much as the science. We offer Court-Admissible DNA testing that follows strict chain-of-custody procedures from check-in through lab analysis so your results are legally defensible.

Our certified collectors verify identification, document every handoff, and seal samples properly so results can be recognized by courts and agencies. This is essential for cases involving child support, custody, Social Security benefit claims, immigration petitions, or changes to a birth certificate.

• DNA Profiling: DNA Profiling establishes an individual genetic profile and is used by legal professionals for parentage verification, twin zygosity, siblinghood, and other proceedings.
• Genetic Reconstruction: Genetic Reconstruction helps prove a genetic relationship when one or more key family members are not available for direct testing.
• Forensic Services: Forensic Services testing is conducted with meticulous sample handling for use in legal matters and can involve a variety of DNA sources.

Court-admissible results require in-person collection at a certified facility with full chain-of-custody documentation, so at-home kits are not appropriate when you need court-admissible DNA evidence. We use partner facilities that are accredited by AABB to conduct legal, chain of custody testing.

• Forensic Services: Our Forensic Services can evaluate DNA from hair, skin, and other specimens for individual identification, evidence review, or comparison to existing profiles, using principles similar to forensic DNA analysis.

What To Expect From Our DNA Testing Process

We keep the testing experience simple and respectful. When you arrive, you check in, complete a short set of forms, and are brought back for collection, usually within minutes. Our team explains each step so you always know what is happening and why.

• Collection: For most tests, we use a minimally invasive buccal swab sample collection from the inside of the cheek. This method is quick, painless, and requires no needles for the majority of relationship tests.
• Handling and chain-of-custody: Certified collectors follow strict industry standards, including chain-of-custody procedures when required, to protect sample integrity and maintain accurate records.
• Confidentiality: We handle specimens and personal documentation securely, limiting access to authorized staff and protecting your privacy from start to finish.
• Special samples: When a case calls for it, we can coordinate testing of alternate DNA sources, including hair and skin, especially for Forensic Services needs.

Once your sample is collected, we use facilities that are accredited by AABB to conduct legal, chain of custody testing, and your results are processed as quickly as possible based on the specific test type.

DNA Testing FAQs

What Is The Difference Between Legal And Non-Legal DNA Testing?

We offer both Legal and Non-legal DNA tests. Legal tests follow full chain-of-custody procedures at our certified facility and include the documentation courts and agencies expect. Non-legal tests are designed for personal knowledge only and do not carry that level of documentation.

Do All Parties Need To Come In Together?

Not always. For many legal DNA testing situations, we can coordinate so each party visits a certified collection site separately. Our team works with you to plan a schedule that fits everyone’s availability while maintaining proper identification and documentation.

How Can I Use Legal DNA Test Results?

Court-admissible DNA results may be used to support child custody and child support decisions, birth certificate amendments, Social Security benefit claims, immigration cases, and other legal matters where biological relationship verification is required.

Is DNA Testing Painful?

No. The standard method for most DNA testing is a quick cheek swab, which is painless and does not involve a blood draw for the majority of relationship tests.

Can You Help With Immigration And Other Official Cases?

Yes. FastestLabs of Bethesda assists with Immigration testing, legal proceedings, and personal family matters. We guide you through the paperwork requirements, coordinate any multi-party collections, and help ensure your immigration DNA documentation or legal records are prepared correctly.
