Forensic Samples

A forensic sample is simply an alternative sampling method to the ordinary mouth swab. An ordinary saliva sample is a standard sample whilst a forensic sample is sometimes referred to as a non-standard sample.  Commonly used forensic samples might include blood or hair; however, collecting forensic samples is not always simple and straightforward as there may be strict collecting procedures involved. Moreover, using forensic samples may be subject to certain laws depending on the country you live. Different forensic samples offer different success rates. Some offer a higher probability than other for extracting DNA; for example a used Kleenex has a high success rate whilst an envelope a low success rate. If the DNA is successfully extracted, then the testing procedure can proceed as normal and the results will be as accurate as for any other DNA test.
