Karius Test Performance Data

Analytical Performance & Clinical Validation

1. Blauwkamp, et al. Nat Microbiol 4, 663–674 (2019).

*Discordant Karius results included clinically-relevant pathogens such as Helicobacter pylori, EBV, and CMV that were determined not to be the primary cause of sepsis via adjudication. For a summary of the analytical validation see: kariusdx.com/validation.

AMR Clinical Validation Performance Summary

PPA = Positive Percent Agreement

NPA = Negative Percent Agreement

Overall Yield: Calculated by sum of presence and absence calls for an AMR marker, divided by the sum of all microbes in that drug class category  that could have those markers Orthogonal confirmation methods included: blood culture, Vitek, Microscan Walkaway, Agar dilution, E test gradient strip, and other microbiology tools

*Samples chosen may not represent pathogen abundance distribution in targeted patient population

**False positives come from samples where orthogonal confirmation was limited
