- A negative result: in this case, the presence of semen or sperm has been excluded
DNA testing following a semen detection test
If the semen detection results are positive, you may wish to carry out an infidelity DNA test. What we will do in this case is actually to attempt to extract the DNA from the sample used in the semen detection test and compare this to another DNA sample (usually a mouth swab sample). If the DNA profiles from the two samples are an exact match we can confirm that these two samples belong to the same individual. For more information about our infidelity testing service, click here. Note that the turnaround time for this additional test is 13 working days. It is important to keep in mind that we will first need to carry out a DNA verification test – not all semen samples contain DNA or enough/viable DNA for a comparison test.
Please note this is not a DIY instant home test that can detect the presence of semen instantly by rubbing a solution on an affected area and observing a colour change. Home semen detection kits are known as presumptive tests and only provide an indication as to whether semen is present or not. Presumptive tests also have a chance of false positives and are thus only reliable when it comes to excluding the presence of semen.
