Paternity Test Lab

Legal/court admissible Paternity DNA test

When legal matters require proof of biological parentage, a legal paternity DNA test provides the court-admissible documentation you need. Whether it's for child support, custody disputes, immigration cases, Social Security claims, or amending a birth certificate, our testing process meets strict legal standards and is fully recognised by courts and government agencies.

At Optimal Lab Test Houston, all legal paternity testing follows the AABB-accredited chain-of-custody protocol to ensure every step, from sample collection to results, is handled with the highest level of accuracy, identification, and documentation.

When Is a Legal Paternity Test Needed?

• Child support or custody hearings
• Immigration documentation
• Social Security or inheritance claims
• Updating or adding a name on a birth certificate

What to Expect:

• Certified Collection Process: Our trained professionals follow legal chain-of-custody procedures including ID verification, documentation, and witness signatures.
• Valid Identification Required: Adults must present a government-issued photo ID (e.g., driver’s license, passport, military ID).
• For Minors: A certified copy of the child's birth certificate may be requested.
• Accredited Lab Testing: All samples are processed in AABB-certified laboratories.

If you're facing a legal situation that requires undeniable proof of biological relationship, we provide fast, accurate, and fully admissible paternity test in Houston that courts and legal entities trust.

Non-Legal Maternal DNA test

The non-legal DNA maternity test is a highly accurate way to confirm whether a woman is the biological mother of a child. This test is intended for personal knowledge and is not admissible in court, making it ideal for families seeking clarity or peace of mind.

For your convenience, we offer a private, at-home testing option. A simple cheek swab (buccal swab) collection kit is shipped directly to your home, allowing you to collect the sample quickly and easily, no clinic visit required.

Key Features:

• 100% pain-free cheek swab collection
• At-home kit for privacy and convenience
• Accurate results processed in certified labs
• Fast turnaround time

The DNA collected from both the mother and the child is carefully analysed and compared to identify a biological match. This test offers reassurance in adoption reunions, hospital mix-ups, or any scenario where maternal relationships are in question.

Although commonly associated with fathers, paternity testing in Houston, TX also includes maternity options like this, providing comprehensive family relationship testing through a trusted and confidential process.

Legal Maternal DNA test

Legal Maternity DNA Testing helps to determine a relationship between a biological mother and child. All children inherit half their parent’s DNA—23 chromosomes from the father and 23 chromosomes from the mother. A DNA test analyzes a mother’s contribution to her child even if the biological father is unavailable.

Legal Maternity DNA Testing follows a strict chain of custody collection process, similar to the Legal Paternity DNA Test.

Key Highlights:

• Confirms biological relationship between mother and child
• Effective even if the biological father is not available
• Strict chain-of-custody procedure followed for legal validity
• Accurate and reliable results processed in certified labs
• Part of our affordable DNA paternity testing services

Pre-Natal Non-invasive Paternity DNA test

When waiting isn’t an option, a non-invasive prenatal paternity test offers answers with zero risk to the fetus. This test determines the biological father with over 99% accuracy as early as 7 weeks into pregnancy, without the risk of miscarriage.

How It Works:

• A blood sample is taken from the mother (just like a routine blood draw).
• A mouth swab sample is collected from the alleged father.
• DNA scientists isolate the fetal DNA from the mother’s blood.
• The fetal DNA is compared to the alleged father’s to check for a biological match.
• Genetic markers are analysed to determine the likelihood of paternity.

This advanced method ensures safety for both mother and child while providing reliable, court-ready results.

As part of our commitment to affordable DNA paternity testing, we offer this cutting-edge service with expert care and total confidentiality.

Grandparent DNA test (Legal & Non-Legal)

A grandparentage DNA test helps determine a biological relationship between a potential grandparent and a grandchild. This test is especially useful when the alleged father is unavailable for testing, as his genetic profile can be reconstructed using DNA from his biological parents.

How the Test Works:

• DNA samples are collected from the child, one or both alleged grandparents, and—if possible, the child's mother.
• The more participants included, the more accurate the results.
• Genetic markers are analysed to assess the probability of a biological relationship.

Interpreting Results:

• A grandparentage index value greater than 1.0 indicates a likely biological relationship.
• A value less than 1.0 suggests no biological relationship exists between the tested individuals.
• This test provides a reliable solution in cases where paternity must be established through indirect family DNA analysis.

Immigration DNA test

Immigration DNA testing is used to establish biological relationships such as paternity, maternity, or kinship when requested by the U.S. Embassy, Department of Homeland Security, or United States Citizenship and Immigration Services (USCIS). It plays a critical role in verifying family connections for visa sponsorship, passport issuance, or citizenship approvals.

When Is Immigration DNA Testing Required?

• Requested by USCIS or U.S. embassies
• Needed to verify biological relationships for visa sponsorship
• Required for citizenship applications or passport verification

In these situations, both the accuracy and timeliness of DNA results are essential for successful immigration processing.

Our lab ensures fully accredited, court-admissible results that meet all federal and international requirements. We are proud to be a trusted source for paternity testing in Houston, TX, and are committed to offering affordable DNA paternity testing options for individuals and families navigating immigration procedures.

Siblingship test (Legal and Non-Legal)

A DNA sibling test is used to determine whether two or more individuals are biologically related as siblings. It’s especially helpful when one or both biological parents are unavailable or deceased, making traditional parentage testing impossible.

There are two types of sibling DNA tests:

• Full Siblingship Test: Performed when individuals are believed to share both biological parents.
• Half Siblingship Test:Used when individuals are thought to share only one biological parent.

Common Uses:

• Immigration cases (USCIS, U.S. Embassy)
• Adoption-related questions
• Family reunification efforts
• Parentage verification when a parent is unavailable

Each sibling’s DNA is analysed to assess genetic similarities and determine the likelihood of a full or half-sibling relationship. These tests are reliable and accepted as supporting evidence in various legal and immigration processes.
