In vitro diagnostic medical devices — Multiplex molecular testing for nucleic acids — Part 4: Detection of pathogens

Scope

This document gives the general requirements for detection of pathogens by multiplex molecular tests which simultaneously identify two or more nucleic acid target sequences of interest. This document is applicable to all multiplex methods used for examination using IVD medical devices and laboratory developed tests (LDTs). It provides information for both of qualitative/quantitative detection of nucleic acid target sequences.
This document is intended as guidance for multiplex examinations that detect and/or quantify microbial pathogen nucleic acid target sequences from human clinical specimens.
This document is applicable to any molecular in vitro diagnostic examination performed by medical laboratories. It is also intended to be used by laboratory customers, in vitro diagnostic developers and manufacturers, biobanks institutions, and commercial organizations performing biomedical research and regulatory authorities. This document is not applicable to metagenomics.
