RESUMEN
Clinical metagenomic next-generation sequencing (mNGS) entails unbiased shotgun sequencing of all microbial and host nucleic acids present in a clinical sample. By analyzing the microbiota diversity, taxonomic, and phylogenetic relationships of clinical specimens, metagenomics related analysis provides an opportunity to investigate substantial biological significance of different microbes. According to the published paper, most studies on mNGS mainly focused on the clinical impact evaluation. However, the studies focused on the analytical performance validation of mNGS before clinical application were rare. Here, a scheme, included intended use, method establishment, assay validation and standard operating protocol, for the laboratory validation of clinical metagenomics sequencing assay was provided by summarizing experiences of clinical laboratory department of Peking Union Medical College Hospital protocol and relevant research. In this scheme, we discussed important topics of mNGS laboratory validation as below: specimen type and pathogen list, bioinformatics pipeline setup, dry lab standard preparation and performance validation, mNGS workflow setup, background nucleotide acid evaluation, wet lab standard preparation and performance validation.
RESUMEN
By reviewing the practice of lab administrating system of reform in the School of Chinese Pharmaceutical Science in Guangzhou University of Chinese Medicine in recent years,we think that the setup of administrating system,the running mechanism and the reasonable allocation will be beneficial to and effective for further speeding up the experiment teaching reform in pharmacy specialty and improving the level of experiment teaching.
