Establishment of sample criteria. (A,B) Distributions of the ddEGFR iQC index (A) and DIN value (B) corresponding to sample storage time. The black line indicates the median value (*Genomic Equivalent; ***p < 0.0001). (C,D) Establishment of sample criteria using discordant samples. Discordant samples were analyzed by comparing the results of the Cobas EGFR and ddEGFR tests. Plots show distributions of the correlation between DIN value (C), iQC index (D) and sample storage time of discordant samples. The black line represents the median value. The DIN values and iQC index of discordant samples are distributed under the red dotted line.
