1 · Plate acceptance
A plate passes when R² ≥ 0.98, ≥ 75% of standard levels recover within 80–120% with CV ≤ 20%, a quantifiable range exists, and ≥ 67% of controls with expected ranges fall inside them. Limits are in-well concentrations.

2 · Standard curves
Weighted (1/y^2) least-squares fits. 5PL is chosen over 4PL only when its AICc is lower by more than 2. Weighted residuals should scatter evenly around zero; a curved pattern means the model is wrong for the data. The plate map shows raw OD. Excluded wells are marked ✗.

4 · Dilution linearity
Samples run at more than one dilution should agree after correction (±20%). A concentration that rises with dilution points to matrix interference or the high-dose hook effect.
None.
5 · Inter-plate normalization
Bridge controls shared by every plate estimate a multiplicative plate factor, on the log scale with the average plate as reference. Corrected concentration = raw / factor.
| plate_id | analyte | factor | log_factor_se | n_bridges | bridge_ids |
|---|---|---|---|---|---|
| plate1 | IL-6 | 1 | – | 0 | |
| plate2 | IL-6 | 1 | – | 0 | |
| plate3 | IL-6 | 1 | – | 0 | |
| plate4 | IL-6 | 1 | – | 0 |
None.
6 · Group comparisons
Tests are run on log10-transformed concentrations. Shapiro-Wilk on every group decides between parametric tests (Welch t / Welch ANOVA) and rank tests (Mann-Whitney / Kruskal-Wallis). Omnibus p-values are Benjamini-Hochberg adjusted across analytes; pairwise p-values are Holm-adjusted within each analyte. Hollow points are censored values that were substituted.

| IL-6 | excluded: plate failed QC | 30 |
| IL-6 | substituted: below common LLOQ 46.8 → /1.41 | 77 |
