Figure 4. Bland-Altman analysis of clinical samples using 96-well microplate ELISA, microchip ELISA coupled with a cell phone or a CCD.

Figure 4

The quantification of HE4 in clinical urine samples obtained by microchip ELISA-cell phone was compared with that obtained by conventional microplate ELISA (A–B). The quantification of HE4 in clinical urine samples obtained by microchip ELISA-CCD was compared with that obtained by conventional microplate ELISA (C–D). The mean differences in HE4 quantification are represented by solid lines, with 95% confidence interval indicated by dashed lines.
