Example Infidelity DNA Test Results

One of the most common questions people ask before ordering an infidelity DNA test is:

"What will my results actually look like?"

This guide provides examples of common infidelity DNA test findings and explains how to interpret the information contained within the report.

Depending on the testing performed, your report may include:

Semen Detection results
DNA Detection results
DNA Comparison results
Contributor analysis
Mixed DNA profile findings

Understanding what these results mean can help you better interpret the information provided by the laboratory.

Quick Answer: What Do Infidelity DNA Test Results Show?

Infidelity DNA testing can answer several different questions depending on the test ordered.

Examples include:

Was semen detected?
Was saliva detected?
Was blood detected?
Was DNA present?
Was the DNA male, female, or mixed?
Does the DNA match a reference sample?
Were multiple contributors detected?

The specific information provided depends on the type of test performed.

Example Semen Detection Test Results

Positive Semen Detection Result

A positive result indicates that semen was detected on the submitted item.

The RSID Semen Detection test used by Validity Genetics identifies the human-specific protein semenogelin.

Example finding:

"Item #### produced a POSITIVE result for the presence of semen."

This means semen was detected on the submitted sample.

Negative Semen Detection Result

A negative result indicates that semen was not detected.

Example finding:

"Item #### produced a NEGATIVE result for the presence of semen."

This means no semen was identified on the tested item.

Understanding RSID Semen Detection

Validity Genetics uses a confirmatory RSID Semen Detection Test that detects the human-specific protein semenogelin.

Unlike presumptive semen tests such as:

Acid Phosphatase (AP)
Prostate Specific Antigen (PSA)

RSID Semen testing is a confirmatory method and does not rely on preliminary screening reactions.

Because it targets a semen-specific protein, it provides highly specific results for semen detection.

DNA Detected

A report may indicate:

"DNA from a Male/Female contributor was detected on item ####."

This means DNA was successfully recovered from the submitted sample.

No DNA Detected

A report may indicate:

"DNA was not detected on item ####."

This means insufficient DNA was recovered to generate a DNA profile.

Example Reference Sample Comparison

One of the most common reasons individuals order an infidelity DNA test is to compare a DNA profile found on an item to a known reference sample.

Reference Sample Included

A report may state:

"The DNA profile obtained from the Reference Swab is consistent with the DNA profile(s) obtained from the tested item and cannot be excluded as a contributor."

This means the DNA profile found on the evidence is consistent with the DNA profile from the submitted reference sample.

Reference Sample Excluded

A report may state:

"The DNA profile obtained from the Reference Swab is inconsistent with the DNA profile(s) obtained from the tested item and can be excluded as a contributor."

This means the DNA profile found on the evidence does not match the submitted reference sample.

Example Mixed DNA Profile Results

Sometimes multiple individuals contribute DNA to the same item.

In these cases, the report may indicate:

"Item produced a mixed DNA profile from multiple contributors."

This means more than one person's DNA was detected.

Male and Female Contributors

A report may state:

"At least one contributor is Male and one contributor is Female."

This means DNA from both male and female contributors was detected.

Indeterminate Contributors

In some cases, the laboratory may determine that multiple DNA contributors are present but may not be able to separate every profile individually.

This may occur when:

DNA profiles overlap
contributor quantities vary significantly
DNA is limited or degraded

What If Semen Is Detected But No Male DNA Is Found?

This is one of the most common questions regarding semen detection testing.

A positive semen detection result does not always guarantee a recoverable male DNA profile.

Possible explanations include:

extremely low DNA quantity
DNA degradation
vasectomy
oligospermia
aspermia

Because RSID Semen testing targets semenogelin rather than DNA, semen may be detected even when a DNA profile cannot be developed.

Understanding Your Infidelity DNA Results

Infidelity DNA reports are designed to answer specific questions about biological evidence found on submitted items. Depending on the testing ordered, the report may identify biological fluids, DNA contributors, DNA matches, or mixed profiles.

Understanding what these findings mean can help you interpret the results and determine whether additional testing may be appropriate.
