The same test, reimagined… As of March 17, 2025 the Karius Test® has been rebranded to Karius SpectrumTM. Click here to learn more.

From a single blood sample, the Karius Test can non-invasively and rapidly detect over 1000 pathogens causing both deep-seated and bloodstream infections.

This webinar explores the application of metagenomic sequencing of plasma microbial cell-free DNA for the detection of pathogens associated with febrile neutropenia. The Karius Test, a liquid biopsy for infectious diseases, utilizes a single blood sample to identify over 1000 pathogens for various diagnostic purposes, including fever of unknown origin, invasive fungal infections, pneumonia, endocarditis, and febrile neutropenia. Our featured speaker, Dr. Negar Ashouri, reviews some of the published data and shares insights on the optimal use of the Karius Test for febrile neutropenia. Dr. Ashouri also shares some of her own patient cases describing the clinical impact of the Karius Test in febrile neutropenia.

ASM 2024 Evening Event Panel - Unraveling the Mysteries of Infectious Diseases: The Role of Metagenomic Sequencing in Your Laboratory

This webinar will explore the application of metagenomic next-generation sequencing of plasma for the detection of invasive fungal infections. The Karius Test, a liquid biopsy for infectious diseases, utilizes a single blood sample to identify over 1000 pathogens for various diagnostic purposes, including invasive fungal infections, pneumonia, endocarditis, and febrile neutropenia. Our featured speaker, Dr. Martin Hoenigl, an infectious disease specialist and expert in the field of clinical mycology, will review some of the published data supporting use of the Karius Test for detection of pathogens associated with invasive fungal infections, including his own research on its diagnostic performance for COVID-19 associated pulmonary aspergillosis. He will also share insights on the optimal utilization of the Karius Test for invasive fungal infections.
