ABSTRACT
With the exception of red blood cells, DNA is found in every human cell. Consequently, DNA is present in a variety of body fluids and tissues that have been demonstrated to be suitable for DNA typing. However, if the sample or evidence collection is performed improperly, the sample’s integrity may be compromised, leading to contamination or degradation. Improper handling procedures during storage and transport from the crime scene to the laboratory can result in samples unfit for analysis. The importance of sample integrity cannot be overemphasized since ambiguous data/information can compromise the investigation or the outcome of the case.
