Audit the context behind AMR discordance

Genotype-phenotype concordance check: place each resistance call beside the quantitative susceptibility result, drug, testing method, breakpoint version, and lineage. For discordant isolates, also report relevant assay conditions and whether the determinant is intact and expressed. Without that context, a marker error cannot be separated from a phenotype or interpretation effect.

Can breakpoint changes reverse genotype–phenotype concordance?

When an antimicrobial-resistance genotype is labeled concordant or discordant, is the underlying susceptibility result reinterpreted under each breakpoint version? Please place the resistance call beside the MIC or zone diameter, drug, testing method, breakpoint standard and version, and lineage. This would distinguish genuine genotype failure from category changes caused by revised thresholds.

Where do resistance-marker errors concentrate?

For each antimicrobial-resistance marker, can false-susceptible and false-resistant calls be reported separately by lineage? Pair the genotype with measured susceptibility, drug, testing method, and breakpoint version. Pooled concordance can hide a determinant that transfers poorly across genomic backgrounds.
