Assay signal values for positive control pool over time. Plots display regression functions for the first point of the positive control with plate number as the time variable throughout the course of data collection for the study. Regression plots displayed individually for pLDH (A), PvLDH (B), and HRP2 (C) antigens with residual plots shown directly below. For each plot, the 41 points shown in gold represent the assay plates repeated due to gross errors in positive or negative controls. For residual plots, assay plates with the first point positive signal outside 2 × SD are labelled.
