Biological evidence is often at the heart of a case, but it can be hard to understand exactly what the scientist is trying to say. In part, this is because of conventions and standards around the way particular types of evidence, especially DNA, are reported. 

In these short guides, we try to give you an understanding of the principles behind some of the terms used and how biological evidence is produced and reported. Please note - these are guides for the non-specialist and, although we make them as correct and accurate as we can, there are some topics that we cannot cover in the level of details that a forensic scientist might expect.

Please contact n-gate ltd. for more information or assistance or to suggest a topic we should address in a future guide.
