Trace – glass, paint, pollen, fibres, hairs
Trace is a termed that applies to a broad range of scientific findings that traditionally fall under the broad heading of physical evidence. It relates to traces of any items that could have been present at a location of interest and includes material such as paint, glass, fibres, pollen, hair, soil and body fluids.
Drug traces generally fall under the category of Drugs even though traces of drugs should be treated in the same way at the point of collection as any other trace evidence, particularly when considering issues of accidental contamination.
Hair analysis for the presence of drugs, particularly in Drug Facilitated Sexual Assault cases, is undertaken by a small number of Experts worldwide – Contact Us for further details.
If trace findings are to be of any evidential or investigative value it is important not only to consider the analytical results but also the manner in which the traces were collected – contamination, dictated by case circumstances, is a significant issue that must be considered.
