The laboratory must have documented its policies and
procedures for the technical and administrative reviews of case records.
This must include:
13.1 Technical Review
Conclusions reported must fall within the range of acceptable opinions of knowledgeable individuals in the field of forensic science or be supported by sufficient data. The laboratory
must therefore, review a sample of case records to ensure that the conclusions of its examiners are reasonable and within the constraints of scientific knowledge. Technical
review, often performed by a peer, may be carried out on a sample of completed case records (for example, 20 per cent or six cases, whichever is fewer per examiner per month). The sampling rate could vary depending upon the situation (for example, a new examiner may have 100 per cent of cases reviewed while a very experienced examiner my have only a few cases reviewed each month). Technical review, while important to the laboratory's quality assurance programme, must not be carried out to the extent that it shifts the perceived responsibility for the scientific findings from the examiner to the reviewer keeping in mind that it is the examiner/reporting officer who presents a sworn testimony to the findings.
13.2 Administrative Review
Administrative reviews must be conducted on all or most of the case records to ensure the completeness and correctness of the reports issued.
This must include:
- the criteria to be used for each type of review;
- the number/percentage of case reports to be reviewed;
and
