Detection of Pulmonary Infectious Pathogens From Lung Biopsy Tissues by Metagenomic Next-Generation Sequencing. INTRODUCTION Metagenomics is the study of metagenomes, genetic material recovered directly from environmental samples. In shotgun metagenomics, whole DNA is extracted from a sample then exposed to random fragmentation prior to NGS. However, mNGS required merely three days to identify 67.23% of cases of MTB infections, whereas 49.58% of MTB infection cases detected using conventional methods required over 90days [13]. A study reported that no significant difference in sensitivity was observed between mNGS and culture in non-antibiotic-exposed patients (43.3% vs. 36.7%; P=0.10) [8]. Highlander SK, Feehery GR, Yigit E, et al. Before LDTs are implemented clinically, proof-of-concept validation with established performance metrics should be performed, which is time-consuming and extremely expensive [24].
