As DNA profiling techniques have become more sensitive, it has become easier to detect DNA and to obtain DNA profiles.  However, the increased sensitivity also often leads to mixed profiles, which require expert interpretation.

It also means that DNA matching an individual can be detected on an item without the person having had contact with the item directly.  Consideration of transfer and persistence can, therefore, be critical in assessing the significance of the findings in the context of the case.  In addition to the DNA results themselves, the interpretation of the DNA findings will also need to take into account other considerations such as the body fluid testing that has taken place, the distribution of body fluid staining, the degree of contact between individuals and the continuity of the collection and preservation of the evidence.
