Testing of Samples Deposited on Various Substrates

DNA test results can be obtained from biological samples deposited on a wide range of substrates (e.g., many types of cloth/fabric found in clothing, bedding, car upholstery, etc. and carpet, glass, tile, wood, plastic, metal, vinyl, wallboard, and latex (gloves, condoms)). Substrates that may be problematic are leather, dirt, or any dirty substrate (e.g., carpet, shoes, car upholstery) and vegetable matter (e.g, leaves).
