Karius plasma microbial cell-free DNA sequencing (mcfDNA-Seq)
Plasma microbial cell-free DNA metagenomic sequencing run in a CLIA-accredited and CAP-accredited laboratory (Karius, Redwood City, CA) against a proprietary reference-genome database, reporting molecules per microlitre for each organism.
Results are recorded on linked configurations and versions of this service. Their settings and evaluations are kept separate below.
Results on linked records
This service has no results of its own in this release. 2 linked records have results. They are not assigned to the underlying service: each record keeps its own settings and evaluations, and its scores are on its own page.

Evidence
Source checking verifies the cited claim or transcription. It does not establish independent reproduction.
Evidence table
Inspect claims, sources and review details
Trace each statement to its source and review. A context-only reference supports the record generally; it does not verify an individual field. Source checking does not reproduce an experiment.
One row per statement and cited source. Multiple citations are not independent evaluations. Shared locators are labelled explicitly.
