What Infidelity Testing Can Show

Infidelity-related DNA testing is designed to compare DNA found on an item to known individuals. For example, if you bring in fabric that appears to contain bodily fluids, the test can help determine whether that DNA matches or excludes certain people whose samples are provided for comparison.

What Infidelity Tests Can't Show

It is helpful to understand what these tests cannot do. DNA testing cannot describe what happened between two people or when an encounter occurred. It also cannot prove romantic or emotional involvement. Instead, it focuses on whether the DNA on a sample is consistent with one or more individuals and whether any unknown profiles appear.

Why People Seek Infidelity Testing

Many clients choose testing when they find unexplained items, such as clothing or personal products, or when they notice bodily fluid stains that raise questions. Others are anxious about possible links between infidelity and future paternity questions and want more information for their own peace of mind. In any of these situations, our team can walk you through what a test can reasonably show for your specific sample.

Most infidelity tests are used for personal knowledge. They typically are not intended for court and should not be relied on as the only factor in legal decisions. Our staff can explain the general uses and limitations of these tests so you understand how to interpret your results alongside other information about your relationship.

How Infidelity DNA Testing Works

Knowing what to expect from the testing process can make your visit less stressful. In general, infidelity testing involves collecting one or more questioned samples and comparing them to DNA from known individuals. Our collectors will guide you through each step when you arrive at our McAllen lab.

Primary vs Secondary Sample Sources

The most common questioned samples are items that appear to contain bodily fluids, often found on fabric, such as clothing, bedding, or similar materials. These types of samples tend to provide clearer DNA profiles than some alternatives. When bodily fluids on fabric are not available, people sometimes bring in secondary sources like hair, used tissues, or nail clippings. These sources can sometimes be used, although they may not always provide results that are as strong as direct bodily fluid samples.

Exclusion Sample (Typically to Exclude Yourself)

For comparison, we typically request at least one known DNA sample that can be used to exclude or match profiles. Many clients provide their own cheek swab as an exclusion sample. In some situations, additional individuals who might reasonably have contact with the item will also provide cheek swabs so that their DNA can be recognized and set aside during analysis.

Our team can review the report format with you so you know what to expect when you receive your results.

How to Prepare for Your Appointment

To help you prepare for your visit, consider these simple steps:

• Bring any items or samples in a clean, dry container, such as a paper envelope or unused plastic bag, and avoid touching the area that may contain DNA.
• Have a valid form of identification available if requested for documentation purposes.
• Think about which individuals might need to provide cheek swab samples and, when possible, arrange for them to be available.
• Write down any questions you want to ask our staff so you do not forget them during your visit.
