DNA testing is an most widely known for its
use in DNA Paternity testing, which is most commonly used for
the identification of a biological relationship between an
alleged father and child.
However, DNA testing has also been adapted
more recently to be used in cases where infidelity is alleged,
as a means of determining whether male or female genetic
material is present on a particular item, and to confirm the
likely owner of that genetic material. Provided DNA samples are
available from the alleged 'cheater' and his or her regular
partner, it should be easy to determine where additional
suspicious genetic material is present which can then be used as
the basis for further examination in determining where
unfaithful behaviour has been occurring.
DNA Testing - Common samples for
Infidelity testing
DNA samples for infidelity testing are
normally obtained from items of clothing particularly underwear
as well as items such as bed sheets, Kleenex tissues and birth
control contraceptives (e.g. condoms). However, testing can be
applied to any material which is suspected to have biological
material on it. The quality of the sample is important, since
the more biological material is present and the less
contaminated it is, the easier it is to obtain a DNA profile.
Having said that, nowadays DNA testing laboratories have
improved their ability to obtain a DNA profile from limited
samples and therefore they should often be able to obtain a full
or partial profile from a wide range of samples and in various
conditions.
DNA Testing - Confirm or dispel suspicions
If you believe a partner may be engaged in
unfaithful behaviour, DNA testing may be one way to resolve your
suspicions. By submitting relevant samples of suspicious items,
DNA testing procedures can identify first of all if the DNA
present is male or female, thereby giving a preliminary
indication of the likely 'donor' of the sample. The next step is
to produce a DNA profile of the donor of the sample and compare
it to the DNA profile obtained either from the most likely donor
(if known and available), or else against the profile of the
person's regular partner to include or exclude that person.
It is important to bear in mind that whilst
the results of this kind of DNA testing do provide additional
information, they aren't necessarily conclusive of the facts.
DNA testing is no guarantee of an unfaithful occurrence and it
should not be the sole grounds for any drastic action - it
merely points to the fact that foreign genetic material is
present, from which the test subjects must draw their own
conclusions. In other words, DNA results should be treated as a
clue rather than evidence. However, armed with this information,
it may be easier to confront the situation or else dispel any
doubts a person may have.
