Fig. 2. Comparative evaluation of the NGS-MRD and ddPCR tests. The results of the linearity analyses using serially diluted reference material ranged from 5.00% to 0.06%. The best-fit regression equation for (A) the NRAS c.182A>G mutation was y=0.949x, and that for (B) the KRAS c.35G>A mutation was y=0.827x.
Abbreviations: NGS, next-generation sequencing; MRD, measurable residual disease; ddPCR, droplet digital PCR.
