We found a good linear correlation between the microfluidic CLIA and the conventional electrochemiluminescence immunoassay (R=0.98).The microfluidic CLIA has significant advantages over the conventional ELISA in detection sensitivity, dynamic range, instrument size and turnaround time, and can provide more consistent and reliable results than the lateral flow immunoassays. Sensitivity and specificity against clinician-expert-derived case/non-case status in the final validation cohort were high, i.e., 96% (95% confidence interval [95% CI] 92-98%) and 95% (95% CI 92-97%), respectively.
