Why Wrong DNA Results Happen and How to Avoid Them


One of the most common and understandable concerns people have when searching for DNA testing is this simple question:


What if my results are wrong?


This is not just a casual worry. DNA testing can affect families, legal rights, finances, and emotional well being. When results are incorrect, the consequences can be serious. The good news is that wrong results usually do not happen because the science is flawed. They happen when the process surrounding the test is flawed.

Understanding why errors occur and how to avoid them empowers you to choose the right provider and protect your peace of mind.

What Causes Wrong DNA Results


DNA analysis itself is extremely accurate when performed correctly. However, mistakes can happen before the sample ever reaches the lab. The most common causes of inaccurate results include poor sample handling, untrained collectors, broken chain of custody, and working with laboratories that are not properly accredited.


For example, if a sample is mislabeled, contaminated, or collected incorrectly, the results may reflect the wrong person or be legally invalid. Even when the laboratory performs perfectly, a failure in collection or documentation can make results unreliable or unusable in court.


Another major risk factor is using a company that does not clearly distinguish between legal and non legal testing. Many people unknowingly choose a non legal test when they actually need court admissible results. This leads to costly retesting and unnecessary stress.

Why Process Matters as Much as Science


Accuracy in DNA testing is not just about advanced technology. It is about strict procedures and accountability at every step.

At Paternity Testing Solutions, we focus on the entire process, not just the final report. We partner exclusively with AABB accredited laboratories, which are held to the highest industry standards for DNA relationship testing. This accreditation is critical because it ensures the lab follows rigorous quality control and legal compliance protocols.


We also use certified collectors who are trained in proper identification, sample handling, and documentation. Every test follows a strict chain of custody, which means your sample is tracked and protected from the moment it is collected until the results are released. This is what makes results defensible in court and trusted in real life.


How to Avoid Inaccurate DNA Results

If you are considering DNA testing, there are several key steps you can take to protect yourself.


  1. First, always confirm that your test is processed through an AABB accredited laboratory if you need legal or court admissible results. This is one of the strongest indicators of reliability.
  2. Second, make sure the company clearly explains whether your test is legal or non legal and what that means for your situation. Transparency is a sign of professionalism.
  3. Third, ask about chain of custody procedures. If a provider cannot clearly explain how your sample is handled and tracked, that is a red flag.
  4. Finally, choose a company that prioritizes communication and professionalism. You should feel supported, informed, and respected throughout the process, not rushed or dismissed.

Hello friends, December is a season of joy, family gatherings, and the occasional awkward moment at the dinner table when Aunt Sue asks one too many personal questions. While this time of year often brings people closer, it can also highlight relationship uncertainties. At Paternity Testing Solutions, we understand how complex relationships can be, especially when trust is questioned. Today, we’re diving into the benefits, drawbacks, and real-life implications of Infidelity DNA Testing. First and foremost, let me say this: we’re not therapists, psychologists, or licensed counselors. We encourage you to speak with a professional counselor or therapist if you’re navigating complex emotions or struggling with trust issues. That said, as a friend with years of experience in listening and offering support, I’m here to clarify what our service offers and how it can help you find the answers you need. What Is Infidelity DNA Testing? Infidelity DNA Testing is a process that determines if DNA from an article of evidence—like clothing or bedding—matches a known reference sample, such as a swab provided by our client. It’s a discreet and confidential way to uncover the truth while ensuring the highest standards of accuracy.  The Benefits of Infidelity DNA Testing 1. Peace of Mind: When suspicion weighs heavily on your heart, getting definitive answers can help you move forward—rebuilding trust or reevaluating your relationship. 2. Confidentiality: Our process is designed with discretion in mind. From sample collection to result delivery, your privacy is our priority. 3. Clear Evidence: DNA doesn’t lie. If you’re seeking clarity for personal reasons or considering confronting your partner, having scientifically-backed evidence can provide the closure you need. 4. Quick Results: The holiday season is busy enough without drawn-out waiting periods. We’ll ensure you get results promptly so you can enter the new year with clarity. The Drawbacks to Consider 1. Emotional Impact: Getting answers can be challenging. Whether the results confirm or debunk your suspicions, they can stir emotions. 2. Not Legally Binding: Infidelity DNA testing is designed for personal clarity, not legal disputes. If legal action is involved, additional chain-of-custody documentation may be required. 3. Cost: At $450 plus shipping, this test is an investment. However, its peace of mind and clarity are priceless for many clients. Real-Life Scenarios: Holiday Edition Scenario 1: Finding Peace Before the Holidays Amanda suspected her partner had been unfaithful. With holiday plans including both families, she couldn’t face the season without clarity. She chose Infidelity DNA Testing, received her results confidentially, and had the opportunity to address her concerns before Christmas, allowing her to enjoy the holidays on her terms. Scenario 2: A Fresh Start for the New Year John spent months doubting his partner’s faithfulness but hesitated to take action. As the year ended, he decided it was time to enter the new year without lingering doubts. After receiving precise results, he felt empowered to make the best decision for his future.

Welcome back to the Paternity Testing Solutions blog! Today, we're diving deeper into a sensitive and specialized topic: Deceased (Post-Mortem) DNA Testing. This kind of DNA testing is not limited to just paternity—it applies to anyone who has passed away, including for maternity or other familial relationships. Whether you're trying to confirm a biological relationship for legal reasons or peace of mind, this test can provide answers in an otherwise difficult time. What is Deceased (Post-Mortem) DNA Testing? Deceased DNA testing is used to establish a biological relationship with someone who has already passed away. It can help confirm a child's paternity or maternity, resolve family disputes, or clarify inheritance claims. Unlike standard DNA tests involving living participants, post-mortem testing requires extracting DNA from remains, making the process more delicate and sometimes complex. At Paternity Testing Solutions, we handle these cases with the utmost care and respect, working with AABB-accredited labs to ensure you receive the most accurate results possible. However, it's essential to understand that not all samples are guaranteed to yield usable DNA.
