It is important to realize that the presence of more than one DNA profile on an evidentiary item must be considered in the context of other evidence and circumstances of the case. For example, if a suspect's DNA profile is obtained from the analysis of a swab from a rape kit, it may demonstrate that they were in contact with the victim/survivor but does not answer the question of consent or the specific timing of events. The crime laboratory will usually generate a report with an interpretation of the results of DNA analysis, which can sometimes assist in determining the significance of results. For more information on laboratory reporting, see Module 6, Understanding a Forensic DNA Lab Report.
