Collecting and analyzing DNA evidence tops the list of the lab's forensic toolkit, and its ubiquity in shows like CSI and Cold Case has increased public awareness to the point that many jurors in real-world courtrooms expect to see DNA evidence presented -- whether a case calls for it or not.ince then, DNA evidence has played a bigger and bigger role in many nations' criminal justice systems.

Inconclusive results can occur for many reasons: for example, the quality or quantity of DNA may be insufficient to produce inter-pretable results, or the evidentiary sample may contain a mixture of DNA from several individuals (e.g., a sample taken from a victim of a gang rape). As with all DNA testing results, additional testing may be needed and findings should be interpreted in the context of other evidence in the case.
