Central Nervous System Infection Pathogen Targeted Next-generation Sequencing (tNGS) is an accurate detection method that combines the advantages of ultra-high multiplex target amplification and high-throughput sequencing technology. By extracting and enriching nucleic acids from cerebrospinal fluid, using the sequencing platform to sequence the pathogen's genes, and comparing and analyzing sequence information against a database, this kit can identify 115 types of central nervous system infection pathogens, as well as 34 drug-resistant genes/mutation sites, improving pathogen diagnosis efficiency significantly.
