Diagnosis of sepsis has always been based on microbial culture, future analysis will be by Metagenomics NGS with host depletion

The qSOFA score is a bedside prompt that may identify individuals who may have a more poor outcome. Usually for diagnosis of sepsis, the qSOFA score is ≥ 2.

How does PaRTI-Seq work? It utilizes ZwitterIonic Self-Assembly Coating (ZISC) membrane technology. ZISC Membrane Treatment is the sample is then subjected to treatment with ZISC membranes. These membranes are designed to selectively capture and remove host nucleated cells, while allowing the non-host nucleic acids to pass through.

Compare PaRTI-Seq with microbial detection sensitivity with unbiased human host DNA and RNA depletion by CRISPR

• PaRTI-Seq is faster, less difficult, and more suitable for NGS than CRISPR deletion
