Table 1.
Results of repeatability assessment of ten sera, with mean, standard deviation (SD), and coefficient of variation (CV; CV = SD/mean) for each sample from 30 independent runs carried out on different days.

POS1–POS6 are positive samples with a corrected optical density that ranges between 0.4 and 0.75; NEG1–NEG4 are negative samples with a corrected optical density <0.2. BUFFER (PBS (Phosphate-Buffered Saline) alone) sample was used as control.
