1.1. Trace evidence is physical evidence that can result from the transfer of small quantities of materials such as hairs, fibers, paint, tape, glass, and geological materials. The primary focus of this guide is to assist individuals in the detection, handling and preservation of trace evidence in the laboratory. Although the bulk of the procedures and steps included in this guide are applicable in the laboratory settings, certain aspects of trace evidence collection, handling, and preservation can be applicable in the field (i.e. crime scene).
1.2. Some specialized types of trace evidence such as soil (see Guide E3272-21), lubricants, lachrymators, fire debris, and explosives have special considerations for collection that are outside the scope of this document.
