How DNA Testing Works

A Simple, Accurate & Confidential Process

DNA testing is a powerful tool for confirming biological relationships and uncovering genetic information. Whether you're seeking clarity for personal reasons, legal matters, or medical insights, our streamlined process ensures accurate, confidential, and hassle-free testing.

What Is DNA Testing

DNA testing analyzes genetic markers to determine biological relationships or uncover ancestry and medical information. It is widely used for:

Paternity & Maternity Testing – Confirming biological parentage.
Relationship Testing – Including sibling, grandparent, and avuncular tests.
Legal DNA Testing – Court-admissible results for custody, inheritance, and immigration cases.
Infidelity & Forensic DNA Testing – Discreet testing for investigative purposes.


🚨AABB Accreditated Lab Partner

This is actually really important for you. An AABB lab is the GOLD STANDARD for DNA testing. There are only 28 AABB Accredited labs in the US and we have partnered with one so that we can deliver the most accurate, expert analysis possible. If you need a legal paternity test for custody battles, child support mediation, immigration or probate/estate settlements you are required to get one from a clinic partnered with an AABB accredited lab … like NoDoubt DNA.

 

It’s Admissible in court

Legal paternity testing is performed following strict protocols and procedures to ensure that the test results are admissible in court.

The testing process, sample collection, and documentation comply with legal requirements and regulations to maintain the integrity and credibility of the results.


It’s requires a Paper trail

In this case, paperwork is a good thing. Any legal paternity test involves what’s called a chain-of-custody. This is simply the documentation that tracks the DNA samples throughout the testing process to ensure their integrity and authenticity form mouth-to-court.

This documentation is crucial for establishing the admissibility of test results in legal proceedings.


There’s no DIY

As convenient as drug store & mail order paternity tests are, they cannot be used for legal cases. With legal paternity testing, sample collection must be performed by a neutral third party … like us.

This helps to ensure an unbiased collection, adherence to legal requirements, and the proper documentation of the sample collection process.
