Laboratory accreditation programs provide an important means of ensuring quality control and assurance in the DNA analysis process, by setting minimum standards and procedures, and providing external oversight of adherence to them. The National Association of Testing Authorities, Australia (NATA) operates a national system of laboratory accreditation for forensic science. However, the analysis of poor quality DNA samples may lead to uncertain results requiring substantial interpretation by the forensic scientist, and the potential for human error or varying opinions in the interpretation of the results. polymerase chain reaction (PCR) based testing is relatively insensitive to degradation. The accuracy of DNA analysis depends on the quality control and quality assurance procedures in the forensic laboratory. As in this case, those difficulties will include the poverty of the sample, its mixture with the bodily fluids of others, the age of the sample, the effect of the re-amplification process or the reliability of results and whether—because of or in spite of the encountering of these difficulties—any statistical probability can be pronounced as to the likelihood of other members of the community producing the same ‘match’. Its value can be compromised by contamination from extraneous DNA anywhere along the chain from the crime scene to the laboratory where the sample is sequenced. The DNA samples collected from each crime scene, including the assault, had been analysed in the same forensic laboratory. The guide debunks some of the most dangerous myths about DNA evidence. The DNA samples collected from each crime scene, including the assault, had been analysed in the same forensic laboratory. Existing legal framework or new legislation? in Business Administration from Pepperdine University. Is DNA evidence the most foolproof way to determine if someone has committed a crime?

Police were satisfied the assault victim had not been at either of the homicide scenes at any time, and was not the offender. Also, DNA evidence is extremely reliable in most cases.
