Karius is your partner in diagnosing infections.

Genomic Insights for Infectious Diseases

The Karius^® Test is a blood test based on next-generation sequencing of microbial cell-free DNA. It can identify and quantify over 1,000 clinically relevant pathogens including bacteria, DNA viruses, fungi, and parasites. Applications include complicated pneumonia, infections in immunocompromised patients, and endocarditis.

Karius^® Test

We use genomics and AI to advance infectious disease diagnostics.

Microbial cell-free DNA

Karius provides unique genomic insights by detecting microbial cell-free DNA (mcfDNA) circulating in the bloodstream from pathogens causing an acute infection. Proprietary technology efficiently extracts mcfDNA directly from blood and depletes the strong human background signal and environmental contaminants.

Karius AI technology

Advanced machine learning algorithms allow analysis of complex genomic data in real-time. Proprietary reference genome databases are constantly refined as more data becomes available.
