Bioanalytical trials: the analytical spine of drug development.
Bioanalytical trials are the analytical spine of every PK, BE, biomarker, and immunogenicity study. It is the operational domain iFeed has the deepest substrate in — production-floor embodied DNA across CRO trenches. The complete package: platforms, regulatory regimes, matrix types, method lifecycle.
What a bioanalytical method is, end-to-end.
Chromatogram · Calibration · BMVA bioanalytical method is three artefacts in tandem. The chromatogram is the raw analytical signal — analyte resolved from internal standard and matrix. The calibration curve is the response-vs-concentration model that turns peak area into concentration, bounded by LLOQ and ULOQ. The BMV pillar set is the discipline of validating that the method holds — the nine criteria ICH M10 names. Read together, they are how a bioanalytical lab gets and keeps regulator confidence.
Selected acceptance values shown in the diagram (e.g., R² ≥ 0.99, Rs ≥ 1.5) reflect widely-adopted industry practice; ICH M10 itself does not specify an R² acceptance threshold and anchors acceptance on accuracy criteria (±15%, ±20% at LLOQ). Resolution Rs ≥ 1.5 is a chromatographic norm (e.g., USP <621>), not codified in ICH M10.

Current state: 2026.
ICH M10 is the central harmonised text. FDA, EMA, WHO/PQT, ANVISA, and PMDA/MHLW source positions need to be read with their own implementation context. iFeed separates official anchors from observed inspection themes.
