Preface

The Scientific Working Group on Microbial Genetics and Forensics (SWGMGF) has developed the following quality assurance guidelines to provide laboratories engaged in microbial forensic analysis with a framework to implement a quality assurance program. This document provides guidance to laboratories that carry out microbial forensic analysis to support the judicial system. Consideration may be given to alternate methods of achieving the intent of these quality assurance practices as outlined in these guidelines. A quality program is always evolving, and likewise, this document should be considered a living document. It is the intent of SWGMGF to modify this document as quality assurance practices in microbial forensics advance.

Introduction

The Quality Assurance Guidelines for Laboratories Performing Microbial Forensic Work provides a baseline from which laboratories may structure their quality assurance practices. Many of the recommendations outlined in this document will be familiar to laboratories already meeting ISO 17025 and CLIA '88 requirements. It is the intent of SWGMGF to provide the community with a source document for quality practices in the microbial forensics field.

1. Scope

These guidelines describe quality assurance activities that a laboratory should follow to ensure the competency of the laboratory and the quality and integrity of scientific data. A laboratory, in the context of these guidelines, is defined as a facility in which microbial forensic testing is performed. These guidelines do not preclude a laboratory, by itself or in collaboration with others, from participating in research and development, or from using procedures that have not yet been validated by standard means for purposes other than forensic testing.

2. Definitions

As used in these guidelines, the following terms have the meanings specified:

Administrative review is an evaluation of examination documentation for consistency with laboratory policies and for editorial correctness.

Analytical procedure is an orderly step-by-step procedure designed to ensure operational uniformity and to minimize analytical drift.

Attribution is the information obtained regarding the identification or source of a material to the degree that it can be ascertained. …
