Human molecular genetics and laboratory microbiology have been revolutionised by the availability of deoxyribonucleic acid (DNA) and ribodeoxynucleic acid (RNA) sequences from humans and microorganisms, and by the development of methods for their detection and characterisation. It is now possible to identify nucleic acid sequences, pathogens and gene mutations rapidly and with a high degree of sensitivity and specificity, through a variety of nucleic acid detection techniques. As a result, these techniques are replacing many conventional laboratory methods such as cell and pathogen culture, immunoassays and protein biochemistry.
The aim of this publication is to provide consensus standards and guidelines for using nucleic acid analysis. It is directed at:
- laboratories that are either using nucleic acid detection techniques in medical diagnosis, or intending to establish a testing program using these techniques
- accreditation authorities such as the National Association of Testing Authorities, Australia, so that laboratories using nucleic acid detection techniques may be assessed for compliance.
