CLINICAL MICROBIOLOGY

A powerful, non-invasive test to rule out infection

Rapid diagnostic tests capable of detecting any potential pathogen are needed to improve the efficacy of antimicrobial therapy and inform antimicrobial stewardship efforts. A new metagenomics-based test that detects microbial DNA in human blood can identify a diverse array of pathogens from any source in the body.
