Karius

Karius is a diagnostics company that uses microbial cell‑free DNA and next‑generation sequencing to detect infectious pathogens from a noninvasive blood test. Their assay screens broadly for bacteria, viruses, fungi, and parasites to enable earlier, more comprehensive, and more precise infection detection and monitoring. Karius works with clinicians and health systems to support decision making in complex cases such as immunocompromised patients, transplant recipients, and suspected sepsis. Providers choose Karius for its broad pathogen coverage, rapid turnaround, and ability to identify hard‑to‑culture organisms.
