In contrary to what most people think human DNA cannot be extracted from any body fluid or tissue. There are specific samples that we accept (e.g. saliva, semen, blood, hair, nails etc.) These samples have the possibility of containing the DNA required to proceed with testing. DNA can also be extracted from any item that is contaminated with certain body fluids (chewing gum, cigarette butts, sanitary towels etc.) Please refer to our forensic DNA Samples section and review our non-standard sample price list to see what is acceptable for DNA testing. It is important to consider the success rate of each forensic sample, samples with the highest success rate (e.g. used Kleenex tissue) are have a much better chance of working. Submission of more than one sample might be required in order to obtain the required amount of DNA. Please note that there is an additional charge, displayed beside each sample, for this type of testing.
