Reducing false-positive results in pathogen metagenomics. (a) Four main causes of false-positive results (n = 17). (b) Patterns of background microbes clustered dependent on methods of library preparation and nucleic acid extraction. (c) Summary of the prevalence of background microbes (n = 17). (d) Improved assay specificity after applying filters to remove false-positive results.
