Karius is an infectious disease diagnostics company that applies clinical metagenomics and machine learning to microbial cell-free DNA (mcfDNA) circulating in the bloodstream, detecting pathogens that conventional culture-based testing misses. Its CLIA-certified and CAP-accredited laboratory runs the Karius Spectrum blood test, which screens a single blood draw for more than 1,000 bacteria, fungi, DNA viruses, and parasites, and the Karius Focus BAL test, which detects more than 500 pathogens in bronchoalveolar lavage fluid for lung infections. Results are returned to clinicians managing complex, immunocompromised, and difficult-to-diagnose patients.
