DNA Testing

Paternity DNA Testing: Confirms the biological relationship between a child and alleged father. When the mother is included, the test guarantees at least 99.99% accuracy using buccal (cheek swab) specimens.

Maternity DNA Testing: Verifies biological motherhood, often used for immigration cases, adoption reunification, or legal custody matters. Samples are collected from the child, mother, and—if available—the father.

Grandparentage DNA Testing: Determines the likelihood of a grandparental relationship through one of several combinations:

• Mother, child, and two grandparents
• Mother, child, and one grandparent
• Child and two grandparents
• Child and one grandparent

Avuncular DNA Testing: Establishes the probability of paternity by testing the child with the father’s sibling (aunt or uncle). The mother’s sample is optional but recommended for stronger results.

Siblingship DNA Testing: Compares DNA to assess full or half-sibling relationships. Additional relatives may be needed for conclusive results.

When suspicions arise, DATCS offers discreet and scientifically backed infidelity DNA testing to help bring clarity to emotionally difficult situations. Our tests can detect the presence of foreign DNA on personal items—such as clothing, linens, or undergarments—to determine if biological material from an unknown individual is present.

We maintain strict confidentiality throughout the process, and all tests are conducted in our fully accredited lab to ensure accurate, court-level results. Services include:

• Semen Screening of Evidence: Analysis of up to two visible stains to detect the presence of semen on submitted items.
• Gender Screen of Evidence: Determines the gender of the DNA contributor using Quantifier + Y Quantifier technology.
• DNA Profile of Evidence: Generates a unique DNA profile from the material found on the submitted item.
• DNA Profile of Reference Sample: Buccal swab sample used to compare with the evidence and either confirm or rule out identity.

DATCS provides advanced forensic DNA testing services to support legal investigations, criminal defense, cold cases, and more. Our forensic services are designed for attorneys, private investigators, and law enforcement professionals who require legally admissible, scientifically accurate evidence. We analyze DNA from a variety of biological materials—such as hair, blood, skin cells, or touch DNA—found on evidence or personal belongings. With a secure chain of custody and lab protocols aligned with legal standards, our results are defensible in court and supported by expert witness services when needed.

Whether identifying unknown individuals, verifying evidence, or analyzing samples from complex cases, our forensic team brings decades of experience and technical expertise to every case. At DATCS, we combine state-of-the-art laboratory technology with meticulous documentation, ensuring that our reports meet the highest standards of accuracy and reliability. When justice depends on genetic evidence, trust DATCS to deliver clarity and truth backed by science.

DNA testing is a process that analyzes your genetic material—typically collected through a simple cheek swab or saliva sample—to identify biological relationships, ancestry, or potential health risks. The DNA is extracted in a certified lab and compared against another sample or a database, depending on the purpose of the test. Whether you’re confirming paternity, verifying a family connection for immigration, or exploring your heritage, DNA testing offers scientifically backed answers. It is a fast, accurate, and non-invasive method trusted by legal professionals, healthcare providers, and individuals around the world for life-impacting decisions.

Paternity and relationship DNA testing follows strict procedures to ensure high-quality results. Legal-grade paternity tests offer results with 99.99% accuracy or greater when the mother, child, and alleged father are tested. This level of accuracy makes them legally admissible and widely trusted in courts. Other relationship tests—such as grandparent, siblingship, or avuncular testing—can also deliver high accuracy, though results may vary based on the tested individuals. Proper sample collection and laboratory standards play a major role in test reliability. Always choose an accredited provider like DATCS to ensure you receive the most dependable and valid results possible.

Absolutely! At DATCS and other reputable providers, client privacy is protected through strict security protocols. All DNA samples are handled with confidentiality, and test results are only shared with the authorized individuals involved in the case. Certified labs follow federal and industry regulations, including HIPAA compliance where applicable. Your DNA data is never sold or shared without your permission, and all records are securely stored or destroyed as required. We encourage every client to review the privacy policy before testing to ensure they understand how their information will be managed, stored, and used.

The turnaround time for DNA test results depends on the type of test and the provider. At DATCS, paternity and legal relationship tests typically take 2 to 5 business days once the lab receives your samples. Immigration tests and forensic tests may take slightly longer depending on case complexity.  We also offer expedited services for urgent cases involving legal or court deadlines. Our team keeps you informed every step of the way, ensuring fast, accurate, and transparent delivery.

Legal DNA tests must follow a documented chain of custody and be collected by an unbiased third party. This ensures the identity of the individuals tested is verified and that the results are legally defensible. Home DNA test kits, on the other hand, are collected by individuals at their convenience, making them useful for personal information but not legally accepted. While both tests can be scientifically accurate, only legal DNA tests can be used in court or submitted to government agencies. DATCS provides both options depending on whether your needs are personal or legal.

A court-admissible paternity test must be conducted by an accredited laboratory, involve a non-biased collector, follow a strict legal chain of custody, and include photo identification. Exceptions apply in cases where a photo ID or photograph can’t be obtained—such as with deceased individuals, prenatal samples, incarcerated persons, or law enforcement collections. In these situations, a signed affidavit confirming the identity, completed by a qualified witness (e.g., doctor, coroner, corrections officer), may be accepted. Some laboratories may also provide specific forms for these cases.

Some relationship tests—like siblingship, grandparentage, or avuncular testing—may not always provide a conclusive answer due to the nature of shared DNA. In some cases, adding another biological relative can help strengthen the results. If no additional family members are available, we’ll help you understand the results and explore your options.
