Also, the lowest quantified amounts were 12.5 and 2.4 ng/mL respectively, a 5.2 fold improvement of the detection limit.
NettetThese findings place the LOC platform in a competitive position because of its lower limit of detection. Indeed, ELISA tests fail in detecting GLRaV-3 at dilution factors higher than 1:5, while the LOC platform is able to identify the pathogens down to 1:100 dilutions, showing a limit of detection 20 times better than ELISA.
