    J Forensic Sci 52:110-3. 2007
    ..DNA was only detected in the first 21% of the void from one male subject. The results of this study have implications for the collection of urine samples...

    J Forensic Sci 50:802-8. 2005
    ..A modified QIAamp procedure was used to extract thirty samples, which were subjected to one of five environmental conditions. DNA was recovered from all of these samples, and typing results were obtained on 93% of the samples...
