What is a DNA infidelity test?

The autosomal infidelity test is a scientific genetic analysis that allows for the detection and comparison of autosomal DNA (male and/or female) found on everyday objects or surfaces.

Unlike tests that target only male DNA, this test analyses the entirety of non-sexual DNA, enabling the identification of genetic traces from both men and women.
 

It constitutes a discreet and reliable method for obtaining genetic information from a sample, strictly adhering to ethical guidelines and consent.
Although primarily used in a personal context, this type of analysis can also be applied to other contexts of genetic investigation.
 

⚠️ Please note: the results of an autosomal infidelity test are provided for informational purposes only and cannot be used for legal or administrative purposes.

Samples

The laboratory accepts several types of biological samples, classified according to their success rate:
 

✔ High success rate (≥ 90 %)

  • Saliva or blood on filter paper

  • Toothbrushes, clothing, or stained fabrics

  • Personal items (razors, jewellery, etc.)


◼ Medium success rate (60–90 %)

  • Bandages or old fabrics

  • Chewing gum, cigarette butts


⚠ Low success rate (≤ 60 %)

  • Hair without roots

  • Contaminated or difficult-to-handle items


Please note: old or poorly preserved samples may reduce the reliability of the results.

Procedure

The test allows to determine :
 

  • the presence of one or more DNA on the analyzed support,

  • the gender of the detected individuals (male and/or female),

  • and, if the sample is usable, the establishment of a detailed genetic profile.


Included option: DNA comparison

A comparison with a saliva sample can be performed to verify if the detected DNA corresponds to that of the tested person. This option is valid for both male and female DNA.

Infidelity Test

Y-STR Infidelity Test - 234€

The Y-STR infidelity test is a targeted genetic analysis designed to specifically detect the presence of male DNA on a sample by examining the Y chromosome.
When the sample is usable, a Y-STR genetic profile can be established.
 

The test includes a comparison with a male saliva sample to verify whether the detected DNA matches that of the tested individual.

Order

Combined Autosomal and Y-STR Infidelity Test - 319€

The combined autosomal and Y-STR infidelity test is a comprehensive genetic analysis designed to detect both autosomal DNA (male and/or female) and specific male DNA via the Y chromosome on a sample.

It identifies the number of DNA traces detected for each gender and, when the sample is usable, allows the establishment of autosomal and Y-STR genetic profiles.

The test includes a comparison with a saliva sample to verify whether the detected DNA matches that of the tested individual.

Order

Y-STR Profile Detection - 179€

Y-STR profile detection allows the identification of male DNA on a sample through Y-chromosome analysis.
 

This test confirms the presence of one or more traces of male DNA, without establishing a detailed genetic profile.
It provides a simple and fast solution to verify the presence of male DNA before proceeding with more in-depth analysis.

Order

Autosomal Profile Detection - 179€

Autosomal profiling detection enables the identification of the presence of male and/or female autosomal DNA on a substrate (object, clothing, fabric, etc.).

The test indicates whether there is one or more DNA traces as well as the gender of the detected individuals, without establishing a detailed genetic profile.
This represents a rapid and discreet solution to confirm the presence of DNA prior to more in-depth analysis.

Order

Saliva Detection - 129€

Saliva detection allows for confirming the presence or absence of human saliva on a substrate (object, fabric, clothing, etc.).

This test provides a simple and reliable answer, without DNA analysis or genetic profiling. It is a quick solution to check if a substrate has been in contact with saliva.

Order

Blood Detection - 129€

Blood detection allows confirmation of the presence or absence of human blood on a sample (object, fabric, clothing, etc.).
 

This test provides a simple and reliable answer, without DNA analysis or the establishment of a genetic profile. It is a quick solution to verify whether a surface contains traces of blood.

Order

Semen Detection - 129€

Sperm detection allows for the identification of the presence of sperm or seminal fluid on a substrate (clothing, fabric, object, etc.).

 

The test reliably confirms whether sperm is present or absent, without DNA analysis or genetic profiling.
It is a quick and discreet solution to obtain a clear answer.
