DNA samples can come from almost anywhere

Foensic DNA Test samples

For DNA testing the most popular and reliable way to collect samples is the oral buccal swab method. Using buccal swabs as a collection method is quick and painless and is the recommended way to collect DNA samples.

In cases where a buccal swab sample cannot be obtained (the individual to be tested is missing, deceased, unwilling or unable to participate) a forensic sample can be submitted for testing. There is an additional fee for each foresic sample. However, the quality of the DNA in a forensic sample cannot be guaranteed. There is a chance that if the DNA in the sample submitted is degraded or insufficient, we may not be able to obtain useful information. The full charges will still apply even if the attempt is unsuccessful.

Examples of samples which are commonly submitted to our laboratory for testing include:

  • Dried blood stains (dried blood on bandages, on tissue, cotton, or paper)

  • Dried saliva stains (cigarette butts, stamps, stains on clothing or napkins)

  • Hair, you will need 6-8 strands per test. (Hair works best if it is taken directly from the head. Hair which has fallen out of the head naturally may work as well. Cut hair will not work, the strands of hair must have roots, that is where the DNA is located)

  • Dried underwear stains (pads, tampons, diapers)

  • Dried semen stains (tissue, underwear, bed sheets)

  • Fingernail clippings can work, but are at a much lower chance of success (6+ clippings to ensure a higher success rate)

  • Teeth (Molar, premolar, and canine work best. Higher costs involved, must contact us to order the test)

Any sample which contains biological material has a chance of working. If you have any questions in regards to your situation, please contact us directly.
