  1. Sensitivity and specificity of CMg compared to qPCR and microbiology testing for four high priority pathogen species according to three reporting thresholds; ≥5 reads assigned to the target species, ≥ 50 reads assigned to the species and 0.1% of the total classified microbial reads assigned to the target species. % classified microbial reads = % of species reads over the total number of taxonomically classified microbial reads obtained
