ILLUSTRATIVE VALUES ONLY. The allelic frequency component (81258-6) is the field of primary clinical interest for a dPCR ctDNA result: it carries the mutant-allele fraction quantified directly by the assay (droplet/bead-positive fraction, Poisson-corrected), which is what a clinician uses to gauge ctDNA burden and track it serially — analogous to how VAF is used from NGS, but here derived from a targeted few-plex assay rather than sequencing depth.

ILLUSTRATIVE: represents that the digital PCR assay interrogated only the EGFR exon 20 T790M hotspot position (and, in a multiplexed panel, a small number of other named hotspots such as exon 19 deletions / L858R) — not the full coding sequence of EGFR. Unlike NGS, a negative dPCR result only rules out variants at the specific positions named here; it should not be read as 'EGFR negative' more broadly. Coordinate/region detail (start/end, genome build) is omitted from this illustrative example and should be populated from the assay's validated target list in a real implementation.
