A sophisticated molecular assay employs high-throughput gene sequencing (NGS) technology to identify and analyze microbial cell-free DNA (mcfDNA) fragments present in blood plasma. These fragments are released into the bloodstream by pathogens (bacteria, fungi, parasites, viruses) during active infection. NGS technology allows for the "reading" of these genetic sequences and their matching against comprehensive databases to identify the organism, providing a complete and unbiased overview of systemic infection without the need for in vitro microbial culture.
