Infidelity DNA Testing | easyDNA South Africa | EasyDNA South Africa

Samples we can analyse

Infidelity testing is based upon the analysis of DNA samples; often clients find suspicious stains or a range of items they believe to have been left behind following an act of cheating. At easyDNA, we are able to test a vast range of DNA samples which we call “discreet samples”.

We have a whole section which gives ample information about many of the most common samples tested including hairs and fingernail clippings. A breeze through our forensic DNA testing section will help you understand more.

An important factor is the way in which a sample has been stored, whether the item has been contaminated (has the item been washed?) and how old the sample is. Different samples offer higher chances of success and we will of course be able to give you solid guidelines; We cannot nevertheless, give you a 100% guarantee. Keep in mind that the sample might not even contain any DNA.

The type of samples submitted for DNA infidelity testing vary; however, the most common samples include hair, underwear, bed sheets, tissues and condoms. Once the DNA samples are at our laboratory, you will receive your comprehensive DNA analysis report in 10 working days.

What does an infidelity DNA test show?

  • Is it human genetic material? Whilst you might think the stain you found to contain human DNA, this may be scientifically incorrect. With a DNA test we can confirm whether the genetic material is human or not and whether the sample you sent in actually contains any DNA at all.
  • Is it male or female DNA? This aspect of the analysis will help you discover whether the sample you sent in contains DNA belonging to a man or to a woman. It is not unusual for us to find mixed DNA profiles during this stage of the test. Establishing the sex of the DNA in the stain is easily done by confirming or excluding the presence of YX chromosomes and XX chromosomes.
  • Identification of donor: Once we have confirmed the presence of DNA, you can opt for further testing. In this case, we can compare the DNA in the sample with another sample you send in. By comparing these two samples, we can determine whether they came from the same person or different people. A match in DNA profiles would clearly indicate the same person is the donor of the two samples tested.

Semen Detection Test

A semen detection test is quick and simple test that will enable you to confirm the presence of semen. If you do not require a full DNA test but just want to know if a strain contains semen or not, check out our semen detection test.
