These guidelines for the collection and preservation of deoxyribonucleic acid (DNA) analysis address the manner of transfer of substances that are biological in nature, namely, blood and bloodstains, semen and seminal stains, tissues and cells, bones and organs, and hairs with follicles, and also consider evidence collection and preservation at a crime scene and at the forensic laboratory and laboratory initial processing procedures.
Abstract
DNA analysis of body fluids is an extremely powerful tool for the identification of an offender, but if physical evidence is not properly recognized, documented, collected, and preserved, it is of no value in a criminal investigation. When collecting any type of body fluid or tissue, it is necessary to take the Universal Precautions for Body Fluids. Gloves must be worn when handling these specimens, and additional protective equipment should be used when appropriate.
