Comparison DNA Profile (Known, reference sample)

A Comparison DNA Profile is used to compare to the DNA from a unknown stain (semen) with a known DNA sample that you choose and collect using our DNASwabTM DNA Collection Kit.

DNA Profiling of Known Sample
DNA sample that you choose and collect using our BIOSWABTM DNA Collection Kit. Once the profile has been generated, our final approach to our DNASLEUTHTM Infidelity Detection Service is the Comparison DNA Profile, in which we will compare the two profiles to establish the donor of the semen or not.

Non-standard samples can also be used as a known sample for profiling at an additional cost ranging from $200 and up. See example of non-standard samples here!

Semen Detection and DNA Profiling of Stain Sample

This is a presumptive test, which determines the presence of acid phosphatase, a major constituent of seminal fluid. The presence of this enzyme generally indicates that male sexual activity has occurred, however, a false positive may be obtained. Therefore, when a stain tests positive, we will conduct DNA profiling of stain sample.

A DNA Profile is performed to determine if there is DNA in the stain. We determine if a male, female, or mixture has contributed to the DNA in the stain, and if there is more than one person's DNA in the stain. In most cases, one unique DNA profile will be generated from the sample.

"I just want to thank the continued professional and courteous service your Customer Service team provided me during the stressful waiting period for the DNA results. I contacted both your phone support and instant chat support teams at least twice and received concerned support each time. Never did I feel like they thought I might be calling too much and needed to be more patient. I truly appreciate their consideration and patience during this time."
