Advanced DNA Analysis for Infidelity and Relationship Answers

DNA Extraction and Comparison Testing is an advanced infidelity DNA testing option designed to determine whether DNA recovered from a personal item matches a known individual. This testing goes beyond detection by extracting usable DNA and comparing it to a reference sample.

It is commonly used when semen or biological material is suspected or has already been detected and deeper answers are needed.

What Is DNA Extraction and Comparison Testing?

DNA extraction and comparison testing involves recovering DNA from biological material found on personal items and comparing it to a known reference sample, such as a cheek swab from a specific individual.

This type of testing is often used in infidelity-related situations where the goal is to determine whether the DNA belongs to a particular person, not just whether biological material is present.

All testing is performed discreetly by accredited laboratory partners using advanced forensic DNA analysis methods.

When DNA Extraction and Comparison Testing May Be Used

This testing option may be appropriate when:

  • Semen or biological material has already been detected

  • You want to know whether the DNA matches a specific individual

  • Standard cheek swab testing is not possible

  • Discretion and confidentiality are essential

  • You need more detailed answers than detection alone can provide

Our DNA experts can help you determine whether this testing option fits your situation.

What Can Be Tested?

DNA extraction and comparison testing can be performed on a wide range of non-standard samples, including:

  • Clothing or undergarments

  • Bedding or fabric materials

  • Towels or personal items

  • Razors, toothbrushes, or other personal effects

DNA recovery depends on the condition of the sample, how it was handled, and exposure to washing, heat, or time. Not all samples will yield usable DNA.

What This Test Can and Cannot Tell You

This test can help determine:

  • Whether usable DNA can be extracted from the submitted item

  • Whether the recovered DNA matches a provided reference sample

  • Whether the DNA does not match the comparison sample

Important limitations:

  • DNA recovery is not guaranteed

  • Degraded or cleaned samples may not yield results

  • Results depend on sample quality and quantity

We prioritize transparency so you know what to expect before testing.

FAQ About Infidelity DNA Tests

  • Choose between a Full Sibling and Half Sibling Test.
    A half sibling test only test to see if one parent is in common between the participants. A full sibling test checks to see if the participants have both parents in common

  • Yes, a sibling DNA test can be used to confirm a possible relationship discovered through ancestry testing. The test analyzes specific DNA regions inherited from each sample provider’s parents, assessing genetic similarities and calculating an accurate probability of relationship.

  • A sibling DNA test is just as accurate as a paternity test, but the conclusiveness of the results can have more variation.
    For example, the probability of a relationship between a father and child is almost always 99.9% or higher—or 0% if he’s not the father—but for a sibling DNA test, the probability of a relationship might be 91%, which is still considered a conclusive result.

  • Yes, a sibling DNA test can be used for legal reasons as long as a chain-of-custody procedure has been set up and followed. Results from a legal sibling DNA test are court-admissible and can be used for legal reasons such as Social Security, inheritance rights, immigration, custody, and more. Results for an at-home sibling DNA test kit cannot be used in court.

  • The cost of DNA testing services may vary depending on whether you need results simply for personal knowledge (at-home test) or for court (legal test). It also depends on the number of tested parties, whether the mother is testing, etc.

  • The probability of relationship (PRI) is given as a percentage in your sibling DNA test results report. You can interpret your results based on the following:

    • Above 90.9%: the sibling relationship is supported by DNA testing

    • 9.09% – 90.9%: inconclusive result, and additional parties need to be tested

    • Below 9.09%: the sibling relationship is not supported by DNA testing

    If a probability of relationship (PRI) of 93% is given for a sibling test, the result could be understood as: “There is a 93% probability that the persons tested share a full sibling relationship.”

  • Yes. When two potential siblings and a mother are DNA tested together, then the probability of an inconclusive result is lower, hence raising the chance that the test will give a conclusive result.
