  1. Does prior antimicrobial therapy influence Karius Test results?

    The Karius Test can detect cell-free DNA (cfDNA) from dead and dying pathogens released into the bloodstream. Therefore, the cfDNA signal of a pathogen may still be detected even when a patient has been pre-treated with antibiotics

 

  1. What is the Karius Test process?

    The Karius Test is a simple and efficient process. One 5 mL blood sample should be collected in a plasma preparation tube (PPT), centrifuged at your hospital, and then shipped overnight to Karius. Karius Test kits, which include collection tubes and shipping supplies, are supplied by Karius. Results are typically reported one day after sample receipt.
