DNA testing services provide a valuable service to people who are involved in civil disputes as to parentage or inheritance, as well as playing a vital and ever-growing role within the criminal justice system. Although the techniques of DNA testing are relatively young compared to the vast majority of established science, they have been used successfully in many criminal cases in the last twenty years. They have even been used to overturn wrong convictions on cases which went to court before DNA was ever discovered. It is important to realize, though, that this technology still has its limitations.
There have been many celebrated cases where testing procedures have not been properly followed, often leading to the results being meaningless even before the samples went to the laboratory. The testing equipment was either not manufactured to a high enough standard, or else it was contaminated by the DNA of someone irrelevant to the case. There are also cases where it is uncertain as to how the exhibits have been stored, and cases where the samples are so small they can only be tested by modern controversial techniques.
DNA testing services are used by modern crime detection and prevention departments for all kinds of purposes. The DNA on any given exhibit may be able to match with someone whose DNA is stored in a data bank somewhere. The most unlikely matches have often suddenly thrust a previously unsuspected individual into the limelight, and then when further investigations are carried out, a pattern emerges. The storing of DNA on data banks is only likely to increase in the future, giving more possibilities of this type of event occurring.
The use of these services in paternity and other civil cases is also increasing, with more people being prepared to pay money for definite evidence that they are the parent of a child. This can not only help you gain a favorable outcome in a court case, it can even help you avoid the need for court in the first place. Very few people will pay money to fight a case when they know that there is clear DNA evidence against them.
To use DNA testing services, you only need to provide samples which can be analyzed genetically. These samples are usually taken using buccal swabs, which are painless to use, and easy to forward through the post should you have ordered a home testing kit. It is perfectly possible to use other samples should this not be possible, and there is always the possibility of attending a center in person. If you are going to be relying on your evidence in court, it will be a good idea to have your test recorded and authenticated by one of the established DNA testing services.
